storing the file object in a memory, acquiring the size of a corresponding file according to the file object, detecting whether there is a file in the folder, and a size of the file is known and the file has been traversed and used, and if so, deleting, from the memory, the file object corresponding to the file; and acquiring the total size of files in the folder according to the size of each file in the folder. ## Claims ### Claim 1 A file processing method, comprising: receiving a file access path; when the file access path exists and the file access path corresponds to a folder, generating a folder stream according to the folder, traversing the folder stream, and generating a file object corresponding to the folder stream;

and the step of generating the folder stream according to the folder and traversing the folder stream comprises: generating the folder stream according to files in the folder, wherein the files are located at the same level as the sub-folder; generating a sub-folder stream according to files contained in the sub-folder; and traversing the folder stream, and traversing the sub-folder stream after the traversal of the folder stream is completed. ### Claim 2 (depends on 1) The file processing method according to claim 1, wherein after generating the folder stream according to the folder, the method further comprises: generating an iterator according to the folder stream; and the step of traversing the folder stream comprises: traversing the folder stream by using the iterator. ### Claim 3 (depends on 1) The file processing method according to claim 1, wherein when it is determined that the file access path corresponds to an access file, the method further comprises: generating a file object corresponding to the access file, storing, in the memory, the file object corresponding to the access file, and acquiring a size of the access file according to the file object corresponding to the access file. ### Claim 4 (depends on 1) The file processing method according to claim 1, wherein traversing the folder stream comprises: when a file in the folder stream is a valid file, performing the step of traversing the folder stream and generating the file object corresponding to the folder stream. ### Claim 5 (depends on 4) The file processing method according to claim 4, wherein the valid file is a non-shortcut file. ### Claim 6 (depends on 4) The file processing method according to claim 4, when a file in the folder stream is a invalid file, skipping the invalid file and processing a next file. ### Claim 7 (depends on 6) The file processing method according to claim 6, wherein the invalid file is a shortcut file. ### Claim 8 (depends on 1) The file processing method according to claim 1, wherein when it is determined that the file access path does not exist, the method further comprises: sending a prompt of file access path error. ### Claim 9 (depends on 1) The file processing method according to claim 1, wherein the folder stream is generated by queuing files contained in the folder. ### Claim 10 (depends on 1) The file processing method according to claim 1, wherein generating the file object corresponding to the folder stream comprises: sequentially reading the files contained in the folder, and once a file is read, generating a file object corresponding to the file. ### Claim 11 A file processing device, comprising a memory and one or more processors, wherein the memory stores computer-readable instructions, and the computer-readable instructions are configured to cause, when executed by the one or more processors, the one or more processors to: receive a file access path; when the file access path exists and the file access path corresponds to a folder, generate a folder stream according to the folder, traverse the folder stream, and generate a file object corresponding to the folder stream; store the file object in a memory, acquire a size of a corresponding file according to the file object, and when it is detected that there is a file in the folder, and a size of the file is known and the file has been traversed and used, delete, from the memory, the file object corresponding to the file; and acquire a total size of files in the folder according to a size of each file in the folder; wherein the computer-readable instructions are further configured to cause the one or more processors to: when there is a sub-folder in the folder, screen out the sub-folder from the folder; and generate the folder stream according to files in the folder, wherein the files are located at the same level as the sub-folder; generate a sub-folder stream according to files contained in the sub-folder; and traverse the folder stream, and traverse the sub-folder stream after the traversal of the folder stream is completed. ### Claim 12 (depends on 11) The file processing device according to claim 11, wherein the computer-readable instructions are further configured to cause the one or more processors to: generate an iterator according to the folder stream; and traverse the folder stream by using the iterator. ### Claim 13 (depends on 11) The file processing device according to claim 11, wherein the computer-readable instructions are further configured to cause the one or more processors to: generate a file object corresponding to the access file, store, in the memory, the file object corresponding to the access file, and acquire a size of the access file according to the file object corresponding to the access file. ### Claim 14 (depends on 11) The file processing device according to claim 11, wherein the computer-readable instructions are further configured to cause the one or more processors to: when a file in the folder stream is a valid file, perform the step of traversing the folder stream and generating the file object corresponding to the folder stream. ### Claim 15 (depends on 11) The file processing device according to claim 11, wherein the computer-readable instructions are further configured to cause the one or more processors to: when it is determined that the file access path does not exist, send a prompt of file access path error. ### Claim 16 (depends on 11) The file processing device according to claim 11, wherein the folder stream is generated by queuing files contained in the folder. ### Claim 17 (depends on 11) The file processing device according to claim 11, wherein the computer-readable instructions are further configured to cause the one or more processors to: sequentially read the files contained in the folder, and once a file is read, generate a file object corresponding to the file. ### Claim 18 A non-transitory computer-readable storage media storing computer-readable instructions, wherein the computer-readable instructions are configured to cause, when executed by one or more processors, the one or more processors to: receive a file access path;
