Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order; also, the embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict.

Fig. 1 is a schematic flowchart of a method for identifying different files when copying files according to an embodiment of the present disclosure, where the identifying method is applied to a process of copying files between a hard disk and a usb disk, and a user opens a certain folder of the hard disk and then inserts the usb disk into a computer. As shown in fig. 1, the identification method includes the following steps S101 to S103.

S101, comparing the size of each file in the current hard disk folder with that of each file in the U disk respectively to obtain a first comparison result.

The sizes of the files for comparison are all larger than a preset value, and the preset value is at least larger than 1MB. For example, the file may be a video file.

In this embodiment, only the files with sizes exceeding the preset value in the current folder of the hard disk and the files with sizes not exceeding the preset value in the U disk are compared, and no comparison is performed. Specifically, all files in the current folder of the hard disk exceeding the preset value size and all files in the U disk exceeding the preset value size may be screened in advance, and then comparison may be performed based on the screening result.

The reason for such screening is that the "file size" cannot be used as the only basis for determining whether the files are the same, but when the file size exceeds a certain value, the file size can be used to determine whether the files are the same, for example, a video file is usually large and at least several Megabytes (MB), the number of bytes of different files at this level is difficult to be completely consistent, and on the premise, if the sizes of two files are the same, the two files can be basically determined to be the same, so that the "file size" is suitable to be used as an evaluation standard; in contrast, a text file generally has only ten or several tens of k bytes, and the probability that the number of bytes of different files is the same is very high, so that the "file size" is not suitable as an evaluation criterion. In addition, for a video file, there may be a certain association relationship between the current folder of the hard disk and the U disk, for example, both store the same tv play, and if the file sizes are completely consistent, it may be basically determined that the files are the same; moreover, the number of video files is not large, and the probability that the files are the same in size and different in content can be further reduced on the premise that the file size is the same, so that the accuracy of using the file size as an evaluation standard is further ensured.

The first comparison result includes files of the same size and/or files of different sizes. If the first comparison result includes files with different sizes (may or may not include files with the same size), the following step S102 is executed; if the first comparison result only includes files with the same size but does not include files with different sizes, the current process is skipped and the user can be prompted to: and the current folder of the hard disk is completely the same as the files with the size exceeding the preset value in the U disk.

And S102, recording a set of files with different sizes in the first comparison result as P.

S103, all files recorded by the set P are selected and highlighted.

In the embodiment, when files are copied between the hard disk and the U disk, the files with different sizes are obtained by comparing the files with the sizes exceeding the preset value between the current folder of the hard disk and the U disk and are recorded as the set P, and then all the files recorded in the set P are selected and highlighted, so that the quick identification of different files during file copying is realized.

In addition, under some special conditions, the files with the same file name in the hard disk and the U disk are not necessarily the same file, but in the embodiment, the files with the file name exceeding the preset value size between the current folder of the hard disk and the U disk are compared to identify different files between the current folder of the hard disk and the U disk, so that the problem is solved to a certain extent; of course, the user may select all files and copy and paste the selected files, but still needs to determine whether the files with the same file name are the same one by one, and the above problem cannot be solved.

As an alternative embodiment, the first comparison result only includes a file comparison result of the current folder of the hard disk with respect to the usb disk.

Wherein the file comparison result of the current hard disk folder relative to the USB flash disk refers to: and displaying a comparison result from the angle of the current folder of the hard disk, wherein the files in the current folder of the hard disk are different from the files in the U disk, and the files in the current folder of the hard disk are the same as the files in the U disk.

In this embodiment, the comparison result is only displayed from the perspective of the current folder of the hard disk, so that the user can copy the identified different files from the hard disk to the usb disk.

As another optional embodiment, the first comparison result only includes a file comparison result of the U-disk with respect to the current folder of the hard disk.

Wherein the file comparison result of the U disk relative to the current folder of the hard disk refers to: and displaying a comparison result from the angle of the U disk, wherein the files in the U disk are the same as the files in the current folder of the hard disk, and the files in the U disk are different from the files in the current folder of the hard disk.

In this embodiment, the comparison result is only displayed from the perspective of the usb disk, so that the user can copy the identified different files from the usb disk to the hard disk.

It should be noted that the first comparison result is specifically which comparison result can be selected by the user according to actual needs, in other words, if the user wants to copy the identified different files from the hard disk to the usb disk, the first comparison result is the previous comparison result; and if the user wants to copy the identified different files from the U disk to the hard disk, the first comparison result is the latter comparison result.

In a specific embodiment, before step S101, the following steps S104 to S106 are further included.

S104, acquiring the width of a narrow window on the right side of the current folder window of the hard disk, which displays a file list in the U disk, and the actual length of a file name of each file in the U disk;

s105, comparing the actual length of the file name of each file in the USB flash disk with the width of the narrow window respectively to obtain a second comparison result;

and S106, recording a set of files with file names with actual lengths smaller than the width of the narrow window in the second comparison result as Q.

Correspondingly, step S101 is specifically: and comparing the size of each file in the current hard disk folder with each file recorded in the set Q respectively to obtain a first comparison result.

It should be noted that, when a user opens a certain folder under the hard disk on the computer, after the U disk is inserted into the computer, the narrow window containing the U disk file list is not necessarily popped up on the right side of the current folder window of the hard disk, and whether the narrow window is popped up or not is influenced by factors such as a third-party application, computer configuration, and an operating system. Therefore, the step S104 is executed only when the narrow window containing the U-disc file list pops up on the right side of the current folder window of the hard disc, otherwise, the step S101 is directly executed.

In practical applications, a table may be newly built in the system to store the relevant data, as shown in table 1 below.

TABLE 1

Moreover, each time the current window is switched, the current window information is queried and the relevant data in table 1 above is updated. If the content of the first field is 'not displayed', jumping out of the current process, and directly executing the step S101; if the content of the first field is "display", steps S104 to S106 are performed to compare each LU _i And WR size, recording all LUs smaller than WR _i Corresponding files to form a set Q.

In this embodiment, the files recorded in the set Q are all file name actual length LU in the usb disk _i Files smaller than the length WR of the narrow window are not completely displayed in the narrow window due to the length of the file name, and under the condition that the first half sections of the file names of different files between the current folder of the hard disk and the U disk are the same or similar, it is difficult to visually see which files are unique in the hard disk and which files are unique in the U disk from the current window, which brings trouble to a user in copying the filesFor example, the files with file names having actual lengths smaller than the length of the narrow window in the U disk are screened out and recorded as a set Q, and then the sizes of the files in the current folder of the hard disk are respectively compared with the sizes of the files recorded in the set Q, so as to identify different files between the files. As for the files with file names of which the actual lengths are not less than the lengths of the narrow windows in the U disk, different files between the files can be identified by observing whether the file names are the same or not.

In a specific embodiment, before step S104, the following steps S107 and S108 are further included.

S107, calling current window information stored by the system through a system function;

and S108, obtaining narrow window information for displaying the file list in the U disk based on the current window information.

Correspondingly, the step S104 of obtaining the narrow window width on the right side of the current folder window of the hard disk for displaying the file list in the U disk specifically includes: deriving the narrow window width based on the narrow window information.

In this embodiment, the system of the computer can store the current window information and can directly call the current window information through the system function to obtain the related data; and, every time the current window is switched, the current window information is inquired once, so that the latest current window information is obtained. Specifically, narrow window information for displaying a file list in the U disk is extracted from current window information, the width of the narrow window is obtained based on the narrow window information, and then the file name width can be compared with the actual length of the file name of each file in the U disk to obtain a file with the actual length of the file name smaller than the width of the narrow window.

According to the method for identifying different files during file copying, when files are copied between a hard disk and a U disk, the actual length of the file name of each file in the U disk is compared with the width of a narrow window on the right side of a current folder window of the hard disk, which displays a file list in the U disk, the file with the actual length of the file name smaller than the width of the narrow window is obtained and recorded as a set Q, the files with the sizes larger than a preset value between the current folder of the hard disk and the set Q are compared, the files with the sizes different from each other are obtained and recorded as a set P, all files recorded in the set P are selected and highlighted, and the files which are not on the U disk and a computer hard disk can be conveniently displayed, so that the quick identification of the different files during file copying is realized, the selection speed of the different files between the two is increased, the quick copying of the files between the two is facilitated, the user operation is reduced, and the user experience is improved.
