A data processing method according to an embodiment of the present invention is applied to an electronic device, in which a compressed file 7 is processed in the electronic device, the compressed file 7 can decompress a target file contained in the compressed file 7 to a predetermined file path (storage path) during a decompression operation, so as to enable a user to use the target file, and lengths (lengths of storage paths) of file paths formed during a decompression process of different compressed files 7 are different, which are related to information such as a decompression environment and an environment for creating a compressed packet, but an operating system of some electronic devices limits the lengths of the file paths, so as to possibly cause a decompression failure (for example, the length of the file path exceeds a predetermined length), and the method can overcome this problem, and achieve that the compressed file 7 having an excessively long file path can be correctly and quickly decompressed, as shown in fig. 1, and with reference to fig. 4, the data processing method comprises the following steps:
s1, the length of the file path that the compressed file 7 pre-generates if decompressed is obtained. The length of the file path may also be regarded as the storage depth of the target file generated after the compressed file 7 is decompressed, and when the length of the file path is obtained, the compressed file 7 does not really perform the decompression operation, and in one embodiment, the length of the file path of the compressed file 7 may be obtained in advance by analyzing the related data of the compressed file; in another embodiment, the length of its file path may be obtained by way of a simulated decompression of the compressed file 7 using a virtual environment.
And S2, when judging that the length of the file path exceeds the specified length, when the compressed file 7 is subjected to decompression operation, storing the first content which does not exceed the specified length in the file path in the first directory space of the electronic device to form a first directory, and storing the second content which exceeds the specified length in the file path in the second directory space of the preset electronic device to form a second directory. In the operating environment where the compressed file 7 is decompressed, there is a rule for the length of the file path formed after decompression, and if the length of the file path exceeds the rule length, the decompression will fail. Specifically, a part of the file path which does not exceed the specified length is regarded as first content, the first content is stored in a first directory space of the electronic device, the storage mode can exist in the form of a first directory, so that a user can obtain relevant information of the first content from the first directory, and the storage space of the electronic device occupied by the first directory formed according to the first content can be regarded as the first directory space which is essentially a storage space. Similarly, the part of the file path exceeding the specified length is regarded as the second content, the second content is stored in a second directory space of the electronic device, the storage mode can exist in the form of a second directory, so that a user can obtain the relevant information of the second content from the second directory, and the storage space of the electronic device occupied by the second directory formed according to the second content can be regarded as the second directory space, which is also a storage space in nature. Both the first directory space and the second directory space may be provided in a memory of the electronic device, such as a hard disk of a computer. In one embodiment, the first directory space may be in a display state, and the second directory space may be in a hidden state, so that from the perspective of a user, one compressed file 7 corresponds to only one directory space, and does not interfere with the user. It is important to be able to utilize the coordination between the first directory space and the second directory space to store the super-long file path during the decompression of the compressed file 7, so that the compressed file 7 can be normally decompressed.
For example, a file path exceeding a specified length is … …/a/b/c/d/e, where … …/a/b is a first content (a portion not exceeding the specified length), and c/d/e is a second content (a portion exceeding the specified length), … …/a/b is stored in the first directory space in various ways, such as creating a folder with the first content as a directory in the first directory space; the c/d/e is stored in the second directory space, and the storage mode may be various, for example, a directory of the c/d/e is established in the second directory space.
And S3, storing the target file formed by decompressing the compressed file 7 in the second directory. Further, as described in the above example, the second directory may be a directory established according to the second content in the second directory space, such as c/d/e in the second directory space, that is, the target file is stored in the c/d/e of the second directory space, so that the compressed file 7 having the ultra-long file path can be correctly decompressed, and the target file can be guaranteed to be stored in a memory of the electronic device (in the second directory space), such as a hard disk of a computer.
In an embodiment of the present invention, as shown in fig. 2, after the step of determining that the length of the file path exceeds the specified length, the method may further include the following steps:
and S21, acquiring the excess content initial directory with the excess length in the file path. That is, the critical point is named as the excess content start directory from which convenience is obtained, and the specific example is further described with reference to the above, after the compressed file 7 is decompressed, a file path with excess of the specified length is formed, which is … …/a/b/c/d/e, where … …/a/b is the first content (the portion without excess of the specified length) and c/d/e is the second content (the portion with excess of the specified length), and c can be used as the critical point, that is, the excess content start directory.
S22, generating the first content and the second content according to the position beyond the content start directory. The first content and the second content can be conveniently obtained from the file path according to the position of the exceeding content starting directory in the file path, for example, if c is taken as the exceeding content starting directory, … …/a/b can be regarded as the first content, and c/d/e can be regarded as the second content.
In an embodiment of the present invention, as shown in fig. 3, the step of storing the second content exceeding the specified length in the file path in the second directory space of the preset electronic device includes the following steps:
s23, an index node (inode) of the parent directory in the file path beyond the content start directory is obtained. An inode, which may also be called an inode, stores meta-information data of a file system object in the file system, but does not include data content or file name, and a directory may be regarded as a table combining the name of a file and its inode number, for example, b in file path … …/a/b/c/d/e is an inode, the starting directory beyond the content is c, and the inode of the parent directory in the file path of c is b.
S24, a head directory is created in the second directory space according to the index section of the parent directory. Specifically, since b is easily available in the file path … …/a/b/c/d/e, for example, the index b of its parent directory may be obtained from the content starting directory as c, and the header directory b may be created in the second directory space by taking b as a name after obtaining b.
And S25, associating the second content under the head directory to form a second directory. In one embodiment, the second content may be attached to the head directory, and in connection with the above example, c/d/e may be arranged after directory b to form a directory of b/c/d/e in the second directory space, and the target file may be stored under the directory of b/c/d/e. Thus, the last index section in the first directory … …/a/b in the first directory space is b, the head directory of the second directory c/d/e in the second directory space is also b, and the first directory and the second directory can be linked through the index section b, and certainly can also be linked through other data.
In an embodiment of the present invention, in conjunction with fig. 5, the data processing method further includes the steps of: and when the length of the access file path exceeds the target file with the specified length, acquiring second content from the second directory space, combining the first content stored in the first directory space to form complete directory information, and accessing the target file according to the directory information. The second directory space may be hidden from the user, wherein the stored second content is also invisible, and the first directory space is visible to the user, wherein the stored first content, or the first directory formed by the first content is also visible, the first content and the second content may form directory information of a complete target file, and when the user accesses the target file, the user may first access the first directory formed by the first content in the first directory space, and then may redirect the access address of the user to the second directory in the second directory space (the second directory may be formed according to the second content) according to the complete directory information (or an implicit association relationship in the complete directory information). With reference to the above specific example, the file path is … …/a/b/c/d/e, where … …/a/b is the first content (not exceeding the specified length), and c/d/e is the second content (exceeding the specified length), and the first content and the second content may form complete directory information, i.e. … …/a/b/c/d/e (except that the complete directory information is stored in two different directory spaces respectively), and the target file stored in the b/c/d/e directory in the second directory space can be accessed smoothly according to the complete directory information.
In an embodiment of the present invention, in conjunction with fig. 6, the data processing method further includes the following steps: and when the target file with the file path length exceeding the specified length is deleted, judging whether second content is stored in the second directory space, and if so, acquiring and deleting the target file according to the first content and the second content. Specifically, if the second content is stored in the second directory space, it indicates that the compressed file 7 may decompress the target file into the second directory formed by the second content, and in order to delete the target file, the complete directory information of the target file may be obtained from the first content and the second content, and the target file may be obtained from the second directory in the second directory space according to the complete directory information and deleted. In one embodiment, the second directory formed by the second content may also be deleted after the target file is deleted, or the complete directory information may be deleted.
An embodiment of the present invention further provides a data processing apparatus 1, which is applied in a process of processing a compressed file 7 in an electronic device, as shown in fig. 7 and combined with fig. 4, and includes an obtaining module 2, a processing module 3, and a storage module 4, which are connected to each other.
The acquisition module 2 is configured to acquire the length of the file path of the compressed file 7, if decompressed, pre-generated. The length of the file path may also be regarded as the storage depth of the target file generated after the compressed file 7 is decompressed, and when the obtaining module 2 obtains the length of the file path, the compressed file 7 does not really perform the decompression operation, and in one embodiment, the obtaining module 2 may obtain the length of the file path in advance by analyzing the related data of the compressed file 7; in another embodiment, the obtaining module 2 may obtain the length of its file path by performing a simulated decompression of the compressed file 7 using a virtual environment.
The processing module 3 is configured to, when it is determined that the length of the file path exceeds the predetermined length, store the first content in the file path that does not exceed the predetermined length in the first directory space of the storage module 4 and form a first directory, store the second content in the file path that exceeds the predetermined length in the second directory space of the storage module 4 and form a second directory, and store the target file formed by decompressing the compressed file 7 in the second directory when the compressed file 7 is subjected to the decompression operation. In the operating environment where the compressed file 7 is decompressed, if the length of the file path formed after decompression is specified, and if the length of the file path exceeds the specified length, the decompression will fail, in this embodiment, if it is determined that the length of the file path exceeds the specified length, the processing module 3 may divide the file path into a first content and a second content, where the first content is a part of directory information of the file path, the second content is another part of directory information of the file path, and the first content and the second content are combined together to form complete directory information. Specifically, the processing module 3 regards a portion of the file path that does not exceed the specified length as a first content, and stores the first content in a first directory space of the storage module 4, where the storage manner may be in the form of a first directory, so that a user can obtain information related to the first content from the first directory, and a storage space of the electronic device occupied by the first directory formed based on the first content may be regarded as the first directory space, which is essentially a storage space. Similarly, the part of the file path exceeding the specified length is regarded as the second content, and the second content is stored in the second directory space of the storage module 4, the storage mode may be in the form of the second directory, so that the user can obtain the relevant information of the second content from the second directory, and the storage space of the electronic device occupied by the second directory formed according to the second content may be regarded as the second directory space, which is also a storage space in nature. Both the first directory space and the second directory space may be provided in a memory of the storage module 4, such as in a hard disk of a computer. In one embodiment, the first directory space may be in a display state, and the second directory space may be in a hidden state, so that from the perspective of a user, one compressed file 7 corresponds to only one directory space, and does not interfere with the user. It is important to be able to utilize the coordination between the first directory space and the second directory space to store the super-long file path during the decompression of the compressed file 7, so that the compressed file 7 can be normally decompressed.
For example, a file path exceeding a specified length is … …/a/b/c/d/e, where … …/a/b is a first content (a portion not exceeding the specified length), and c/d/e is a second content (a portion exceeding the specified length), … …/a/b is stored in the first directory space in various ways, such as creating a folder with the first content as a directory in the first directory space; the c/d/e is stored in the second directory space, and the storage mode may be various, for example, a directory of the c/d/e is established in the second directory space.
In addition, as described in the foregoing example, the second directory may be a directory established according to the second content in the second directory space, for example, the second directory may be c/d/e in the second directory space, that is, the processing module 3 stores the target file in the c/d/e of the second directory space, so that the compressed file 7 having the ultra-long file path can be correctly decompressed, and at the same time, the target file can be guaranteed to be stored in the memory (in the second directory space) of the storage module 4, for example, in a hard disk of a computer.
In an embodiment of the present invention, the obtaining module 2 is further configured to obtain an excess content start directory exceeding a specified length in the file path, and generate the first content and the second content according to a position of the excess content start directory. That is, the obtaining module 2 obtains from which location in the file path conveniently exceeds the specified length, and names the critical point as the exceeding content starting directory, and further explains, in combination with the above specific example, the compressed file 7 after decompression forms a file path that exceeds the specified length, which is … …/a/b/c/d/e, where … …/a/b is the first content (the portion that does not exceed the specified length), and c/d/e is the second content (the portion that exceeds the specified length), and then c may be taken as the critical point, that is, may be the exceeding content starting directory. The obtaining module 2 can conveniently obtain the first content and the second content from the file path according to the position of the excess content start directory in the file path, and if c is taken as the excess content start directory, … …/a/b can be regarded as the first content, and c/d/e can be regarded as the second content.
In an embodiment of the present invention, the processing module 3 includes a creating unit, and the obtaining module 2 is further configured to obtain an index node (inode) of a parent directory in the file path beyond the content start directory, so that the creating unit creates a header directory in the second directory space according to the index node of the parent directory, and associates the second content under the header directory to form the second directory. An inode, which may also be called an inode, stores meta-information data of a file system object in the file system, but does not include data content or file name, and a directory may be regarded as a table combining the name of a file and its inode number, for example, b in file path … …/a/b/c/d/e is an inode, the starting directory beyond the content is c, and the inode of the parent directory in the file path of c is b. Specifically, since b is easily available in the file path … …/a/b/c/d/e, for example, the obtaining module 2 may obtain the index b of its parent directory according to the content starting directory being c, and the creating unit creates the header directory b in the second directory space with b as the name after obtaining. In one embodiment, the creating unit may attach the second content to the head directory, and in connection with the above example, the creating unit may arrange c/d/e after directory b to form a directory of b/c/d/e in the second directory space, and the target file may be stored under the directory of b/c/d/e. Thus, the last index section in the first directory … …/a/b in the first directory space is b, the head directory of the second directory c/d/e in the second directory space is also b, and the first directory and the second directory can be linked through the index section b, and certainly can also be linked through other data.
In an embodiment of the present invention, referring to fig. 5, the data processing apparatus 1 further includes an accessing module 5, where the accessing module 5 is configured to, when accessing a target file whose file path length exceeds a specified length, obtain a second content from a second directory space, and combine with a first content stored in a first directory space to form complete directory information, and access the target file according to the directory information. The second directory space may be hidden from the user, wherein the stored second content is also invisible, and the first directory space is visible to the user, wherein the stored first content, or the first directory formed by the first content is also visible, the first content and the second content may form directory information of a complete target file, when the user accesses the target file, the user may first access the first directory formed by the first content in the first directory space through the access module 5, and then the access module 5 may redirect the access address of the user to the second directory in the second directory space according to the complete directory information (or an implicit association relationship in the complete directory information) (the second directory may be formed according to the second content). By combining the above specific example, the file path is … …/a/b/c/d/e, where … …/a/b is the first content (the portion that does not exceed the specified length), and c/d/e is the second content (the portion that exceeds the specified length), and the first content and the second content can form complete directory information, i.e. … …/a/b/c/d/e (except that the complete directory information is stored in two different directory spaces respectively), and according to the complete directory information, the user can smoothly access the target file stored in the b/c/d/e directory in the second directory space through the access module 5.
