Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1, the method for merging files in this embodiment includes:

step S1: acquiring a cat command input by a user, wherein the cat command is used for merging files with different formats;

step S2: acquiring a plurality of first files with different formats to be combined from a designated position according to the cat command; the first file comprises protocol information corresponding to a file format, wherein the protocol information comprises a protocol header positioned at a byte starting position in the file, and the protocol header comprises a byte starting position, a byte ending position and information of byte length from the byte starting position to the byte ending position;

Step S3: splicing the plurality of first files according to the mode that the byte starting position of the next first file is spliced to the byte ending position of the previous first file until all the first files are spliced to obtain a combined file;

step S4: and storing the combined file to the designated position in any one of different formats of a plurality of first files as a storage format.

As described in the above steps S1 and S2, the merging of files of different formats may be implemented by a cat command (cat is a abbreviation of conccate, which means that a plurality of text files are displayed or connected together) which is a command for merging files under a Linux system (a computer operating system), specifically, the command may be directly input by a user, and then the system acquires the command. After the cat command is acquired, the cat command is executed, first a first file to be combined is acquired from a designated position, the first file to be combined is a file prepared in advance, and the first file to be combined is stored in the designated position, for example, a preset database of a storage system, and the first file to be combined is directly acquired from the preset database when needed. The first file is used for merging and spreading, and can be files with different formats, such as video format, PDF format, TXT format and word format. It will be appreciated that merging files of different formats, i.e. merging bytes in the content of multiple files, each file itself carries protocol information including protocol rules, byte lengths, format types, etc. Specifically, the protocol information, such as letters, numbers or a combination of both, may be described by a character agreed by the format, where the protocol information in the file format is specification information of the format, including attribute information such as Length and Identifier, the Identifier is the type of the format, the attribute information may be represented by characters agreed by the format, such as Identifier attribute in the protocol information in the FIF format, the header of the file occupies 5 bytes, the corresponding character is "JFIF" + "0", and the protocol information in the video format includes attributes such as box size, box type, etc., where the box type attribute represents type, occupies 4 bytes, and the corresponding character is a format character (such as "ftyp", "moov") of the video. For convenience of description in this embodiment, the byte with the protocol information in front of the file is defined as a protocol header, and the protocol header includes information of byte start position, byte end position, and byte length from the byte start position to the byte end position.

As described in the above steps S3 and S4, the files with different formats are merged according to the cat command in a byte end-to-end splicing manner, that is, splicing is performed in a manner of splicing the byte start position of the next first file to the byte end position of the previous first file until all the first files are spliced, so that the merged file is obtained, and thus, contents among various formats in the merged file are not interfered with each other. After forming the merged file, the merged file is stored in any one of the different formats of the first file as a storage format in the specified location.

For example, the files 1 and 2 are combined, the files 1 and 2 to be combined are stored to a designated position, then a cat command, such as cat+File 1 (file name) +File 2 (file name) →combined file (name) input by a user, is used, so that the cat command is obtained, the files 1 and 2 are obtained after finding according to the cat command and searching according to the names of the files 1 and 2 at the designated position, then the combination is performed, the beginning position of the 2 bytes of the files is spliced to the ending position of the bytes of the files 1 during the combination, and the combined file name is the combined file (name) input by the operation. When reading by using the reading software, the reading software finds the corresponding protocol header of the first file, analyzes the byte length content of the section and displays the byte length content, and the reading software can be various software for watching file content, such as a PDF reader, a video player, a word reader and the like.

In one embodiment, the step S4 includes:

step S41: acquiring format information input by a user and used for storing the merged file;

step S42: and storing the combined file to the designated position in the storage format according to the format information.

In this embodiment, since the merge file may use any one of different formats of the first file as a storage format, before storing, one of the formats may be selected by the user as a storage format, and then stored, where the format information includes a format suffix name of the merge file, when the format suffix name input by the user is obtained, the merge file may be stored in the format of the format suffix name, and note that the format suffix name input by the user is a suffix name of any one of the different formats of the first file, so that the user may directly store the merge file in a format desired by the user to a designated location after merging according to actual needs, thereby avoiding the trouble of changing the format during subsequent use, for example, a merge file formed by merging a video format file and a PDF format file by the above-mentioned merge method. In another example, if the user wants to promote the merged file after merging the video format and the PDF format of the promotional file to the client, but it is actually more attractive for the client to initially receive the video, then the user may input the format information of the video when storing according to the actual need, so that the storage format of the merged file is the video format, and then promoted to the client.

In one embodiment, the first file includes a JPG format file and a non-JPG format file, and the step S3 includes:

step S31: the non-JPG format files are packed and compressed after being combined through the cat command, so that non-JPG format compressed files are obtained;

step S32: and splicing the non-JPG format compressed file and the JPG format file according to the mode that the byte starting position of the next file is spliced to the byte ending position of the previous file to obtain the combined file.

In this embodiment, the files in different formats may further include JPG format files and non-JPG format files, where the non-JPG format files (such as mp4 format, PDF format, TXT format, word format, etc.) are first combined by the above-mentioned combining method and then compressed, that is, combined according to the cat command and then packed and compressed, so as to obtain a non-JPG format compressed file, then the non-JPG format compressed file is combined with the JPG format files, when the user wants to view the content of the JPG format files in the combined file, the user only needs to open the JPG format files by using a picture reader, if the user wants to view other files that are combined together, then decompress the compressed files by using a decompression tool, at this time, the compressed files are decompressed and then a secondary combined file except the JPG format file is obtained, and then the secondary combined file is viewed by using reading software in a corresponding format.

In summary, by the above-mentioned merging method, a plurality of files with different formats are merged into a merged file, so when the merged file needs to be promoted to a client, the transmission of the plurality of files can be completed only by one transmission channel, and as the files with different formats in the merged file are not interfered with each other, the content corresponding to the format of the reading software in the merged file can be identified by the reading software, and when the content is opened, the content can be extracted for display, i.e. one file can be opened and the corresponding content can be displayed by software with different formats, and the user can open the file for viewing very conveniently.

Referring to fig. 2, the present invention further provides a method for opening the merged file, where the opening method includes:

step S5: acquiring first opening information of a user opening the combined file through reading software,

step S6: judging whether the reading format of the reading software is the storage format according to the first opening information;

step S7: if so, displaying the content of the first file corresponding to the storage format in the combined file according to the first opening information.

In this embodiment, after the above-mentioned combined file is synthesized, the combined file may be propagated and promoted to the user client, where the above-mentioned combined file may be a media propagated propaganda file, and the above-mentioned first file may be files with various formats, such as files with formats of video, PDF, TXT, word, etc. After receiving the combined file, the client may open and view the combined file, and when the user opens the combined file through the reading software, the client obtains the first opening information for opening the combined file as described in step S5.

As described in the above step S6 and step S7, it can be understood that what kind of reading software is generally used can only open the file with the corresponding reading format, for example, the PDF reader can only open the file with PDF, the video player can only open the video file, the word reader can only open the word document file, etc., and if the file with the corresponding reading format is not available, there may be a case that the file cannot be opened and the content of the corresponding file cannot be displayed. And because the reading software adopted by the user is unknown, before the content is displayed, the reading format of the reading software can be obtained through the first opening information, then whether the reading format of the reading software is the storage format of the corresponding combined file is judged, for example, when the combined file is formed by combining an MP4 file and a PDF file, the storage format can be any one of the MP4 file and the PDF file, if the storage format is MP4, the reading format is judged to be MP4, namely, the user is informed that the MP4 player is adopted to open the combined file, and then the content of the MP4 file in the combined file can be displayed according to the first opening information.

In one embodiment, the storage format of the combined file may also be adapted to the reading format of the corresponding reading software by modifying it. The plurality of first files with different formats to be combined include a first file with a first format and a first file with a second format, wherein the storage format is the first format, and after the step S7, the method includes:

Step S71: acquiring modification information for modifying the storage format by a user, wherein the modification information comprises a format suffix name corresponding to the second format;

step S72: modifying the storage format of the combined file from the first format to the second format according to the modification information;

step S73: acquiring second opening information of a user for opening the combined file through reading software corresponding to the second format;

step S74: and displaying the content of the first file corresponding to the second format in the combined file according to the second opening information.

In this embodiment, the first format and the second format may be any one of the formats of video, PDF, TXT, word, etc., and the first format and the second format are different, and the combined file may be modified according to the user's needs (the modified format is the format included in the combined file). Specifically, the first format may be modified to the second format by modifying the format suffix of the merge file, where the modification information input by the user is information for modifying the format suffix of the merge file, and includes the modified format suffix, in this embodiment, the first format needs to be modified to the second format, and then the modification information includes the format suffix corresponding to the second format, for example, a banking company, merges a loan introduction material word document and a promotion small video into one merge file, and sends the merge file to a client, where the merge file is stored in an MP4 format, and then the video file of the merge file may be directly played by an MP4 player, and when its suffix name is changed to the word document suffix (for example, doc), the word file in the merge file may be opened by a word reader.

For example, the propaganda video (MP 4 format file) of company A and detailed text introduction (PDF format) of the product are combined into a combined file, the combined file is promoted to the client of the user in MP4 format, at this time, the user can directly watch the propaganda video by adopting a video player, if interested, the format suffix name of the combined file can also be directly modified, and then the product introduction in PDF format is further checked by a PDF reader, so that the user does not need to interact with company A for a second time, thereby being convenient and saving trouble.

In one embodiment, the step S7 includes:

step S701: finding a protocol header of a first file with a file format being the storage format in the combined file according to the first opening information;

step S702: acquiring a corresponding first byte starting position and a first byte length from the first protocol header, and extracting file content corresponding to the first byte length by taking the first byte starting position as a starting point;

step S703: and analyzing and displaying the file content.

In this embodiment, the first files in each format in the merged file do not interfere with each other, occupy part of the memory in the merged file, and have corresponding protocol headers in the merged file for the reading software to identify. When the combined file is opened by using the reading software, searching a first protocol header of a first file corresponding to the storage format in the combined file according to first opening information obtained during opening, obtaining a first byte starting position and a first byte length from the first protocol header, extracting file contents in the first byte length by taking the first byte starting position as a starting point and the ending position as an ending point, wherein the file contents are file contents corresponding to the storage format, namely the file contents of the first file corresponding to the storage format, and displaying the file contents.

In another embodiment, the user may edit the format of the combined file to obtain a storage format for the combined file for storage. For example, the user directly clicks the merged file to display a plurality of alternative formats, and then selects the formats, for example, mp4, PDF and TXT are included in the formats, at this time, the user can click and select one of the formats, the client can obtain format information input by the user, and the format selected by the user is used as a storage format of the merged file according to the format information and then stored in a designated position of the client. Of course, if the user wants to change to another format, the user can also select to change to another format. Therefore, the step of modifying the format by a user can be saved, and the file with the corresponding format can be opened directly by selecting the format, which is more convenient.

In an embodiment, the format information of the storage format includes a suffix name of the format, and after the step S6, the method further includes:

step S61: if the reading format is not the storage format, judging whether the reading format is any one of the plurality of different formats except the storage format;

step S62: if the reading format is any one of the storage formats except for the plurality of different formats, judging whether the reading software is the reading software capable of ignoring the format suffix name of the file;

Step S63: if the reading software is the reading software capable of ignoring the format suffix name of the file, opening the combined file through the reading software, and displaying the content of the first file corresponding to the reading format; otherwise, stopping opening the combined file.

In this embodiment, when it is determined that the reading format is not the storage format, it indicates that the combined file cannot be directly opened by using the reading software, but the reading format may be any of multiple formats of the first file except for the storage format, and since the same reading format has various different reading software, and the codes of the different reading software for implementing the functions thereof are not the same, some reading software codes may ignore the format suffix name of the file and directly open the file having the reading format, while some may not, for example, a first video player and a second video player may only open the file with the suffix name WMV, and a second video player may ignore the suffix name of the file, so long as the file includes the video file and may be opened, and if the combined file is opened, the displayed content is the first file content corresponding to the reading format, but not the first file content of the storage format. Therefore, the step needs to continuously judge whether the reading format is any one of the storage formats except for a plurality of different formats, if not, namely, the reading format of the reading software is not any one of the formats in the first file, the matched first file cannot be found, and therefore the opening of the combined file is stopped. However, if the reading format is any one of a plurality of different formats except the storage format, it is determined that the reading software is not the reading software capable of ignoring the format suffix name of the file, and because the reading software capable of ignoring the format suffix name can directly identify the corresponding protocol header, when the reading software identifies the protocol header, it can be determined that the reading software is the reading software capable of ignoring the format suffix name of the file, and at the same time, the first file corresponding to the reading format is opened and displayed.

For example, the combined file is formed by combining an MP4 format first file, a PDF format first file and a TXT format first file, and when a user opens the combined file by using reading software, firstly judging whether the reading format of the reading software is the MP4 format, if so, opening the combined file by the reading software is a video file, namely the MP4 format first file; if not, judging whether the reading format is the other two formats except the MP4 format, namely judging whether the reading format is the PDF format or the TXT format, and if the reading format is not the PDF format or the TXT format, opening the combined file at the moment can not be started, namely stopping opening. If the reading format is PDF format, judging whether the reading software is the software capable of ignoring the format suffix name, if yes, opening the first file in PDF format, if the reading format is TXT format, judging whether the reading software is the software capable of ignoring the format suffix name, if yes, opening the first file in TXT format, and if the reading software is not the software capable of ignoring the format suffix name, opening the combined file.

In one embodiment, after the step S62, the method includes:

step S64: if the reading software is not the reading software capable of ignoring the format suffix name of the file, acquiring the reading format of the reading software;

step S65: and changing the format suffix name of the combined file into the format suffix name corresponding to the reading format according to the reading format, opening the combined file through the reading software, and displaying the content of the first file corresponding to the reading format.

In this embodiment, when it is determined that the reading software is not reading software capable of ignoring the format suffix name, that is, the reading software cannot open the merged file at this time, the reading format of the reading software may be obtained and the format of which the reading format is identified, then the format suffix name of the merged file is changed to the format suffix name corresponding to the reading format.

The invention provides a file merging device, which comprises:

The system comprises an acquisition command unit, a command processing unit and a command processing unit, wherein the acquisition command unit is used for acquiring a cat command input by a user, and the cat command is used for merging files with different formats;

As described above in the command unit and the file unit, the merging of files of different formats may be implemented by a cat command (cat is a abbreviation of conccate, which means that a plurality of text files are displayed or connected) which is a command for merging files under a Linux system (a computer operating system), specifically, the command may be directly input by a user, and then the system acquires the command. After the cat command is acquired, the cat command is executed, first a first file to be combined is acquired from a designated position, the first file to be combined is a file prepared in advance, and the first file to be combined is stored in the designated position, for example, a preset database of a storage system, and the first file to be combined is directly acquired from the preset database when needed. These first files are used for merging and spreading, and may be files in different formats, such as video format, PDF format, TXT format, and word format. It will be appreciated that merging files of different formats, i.e. merging bytes in the content of multiple files, each file itself carries protocol information including protocol rules, byte lengths, format types, etc. Specifically, the protocol information, such as letters, numbers or a combination of both, may be described by a character agreed by the format, where the protocol information in the file format is specification information of the format, including attribute information such as Length and Identifier, the Identifier is the type of the format, the attribute information may be represented by characters agreed by the format, such as Identifier attribute in the protocol information in the FIF format, the header of the file occupies 5 bytes, the corresponding character is "JFIF" + "0", and the corresponding character is "JFIF" + "as in the video format, the protocol information includes attributes such as box size, box type, etc., where the box type attribute represents type, occupies 4 bytes, and the corresponding character is a format character (such as" ftyp "," moov ") of the video. For convenience of description in this embodiment, the first several bytes of the file with protocol information are defined as a protocol header, and the protocol header includes information of byte start position, byte end position, and byte length from the byte start position to the byte end position.

The judging and neglecting unit is used for judging whether the reading software is the reading software capable of neglecting the format suffix name of the file or not if the reading format is any one of the storage formats except for the plurality of different formats;

the reading software is used for reading the file with the format suffix name of the file, and displaying the content of the first file corresponding to the reading format; otherwise, stopping opening the combined file.

In this embodiment, when it is determined that the reading format is not the storage format, it indicates that the combined file cannot be directly opened by using the reading software, but the reading format may be any of multiple formats of the first file except for the storage format, and since the same reading format has various different reading software, and the codes of the different reading software for implementing the functions thereof are not the same, some reading software codes may ignore the format suffix name of the file and directly open the file having the reading format, while some may not, for example, a first video player and a second video player may only open the file with the suffix name WMV, and a second video player may ignore the suffix name of the file, so long as the file includes the video file and may be opened, and if the combined file is opened, the displayed content is the first file content corresponding to the reading format, but not the first file content of the storage format. Therefore, whether the reading format is any one of the storage formats is determined continuously, if not, that is, the reading format of the reading software is not any one of the formats in the first file, the matched first file cannot be found, and therefore the opening of the combined file is stopped. However, if the reading format is any one of a plurality of different formats except the storage format, it is determined that the reading software is not the reading software capable of ignoring the format suffix name of the file, and because the reading software capable of ignoring the format suffix name can directly identify the corresponding protocol header, when the reading software identifies the protocol header, it can be determined that the reading software is the reading software capable of ignoring the format suffix name of the file, and at the same time, the first file corresponding to the reading format is opened and displayed.

In one embodiment, the opening device of the combined file includes:

the reading unit is used for acquiring the reading format of the reading software if the reading software is not the reading software capable of ignoring the format suffix name of the file;

and the modification prefix name unit is used for modifying the format suffix name of the combined file into the format suffix name corresponding to the reading format according to the reading format, opening the combined file through the reading software and displaying the content of the first file corresponding to the reading format.
