Detailed ways

As shown in FIG. 1, a file storage management method according to an embodiment of the present invention includes the following steps:

S1, preset multiple operation instructions for file management;

Wherein, before the user performs file management, multiple operation instructions are preset; the multiple operation instructions include, but are not limited to, operation instructions such as adding, deleting, searching, downloading, and marking.

S2. Receive and manage the files stored in the storage medium according to the target operation instructions selected by the user from the plurality of operation instructions.

Wherein, the receiving user selects any instruction from a plurality of operation instructions to manage the files stored in the storage medium by means of remote access (Ethernet or according to the agreed communication protocol).

Wherein, the target operation instruction is: at least one operation instruction among the preset multiple operation instructions.

Among them, the storage medium is a medium commonly used in the market for storing files, including but not limited to: a magnetic disk, a memory stick, and the like.

Preferably, before the step S2, it also includes:

S02, according to the order of storage time, arrange all the storage files in the storage medium to obtain a first directory file list;

The first directory file list is obtained by traversing all the storage files in the storage medium, and sorting all the storage files in the storage medium by time from the latest to the earliest.

Among them, the creation process of the first directory file list is shown in Figure 2. First, it is judged whether there is a date directory under the root directory in the storage medium. If so, then continue to judge whether there is a channel directory under the date directory, and if so, continue to judge the date directory. Whether there is a file in the channel directory, if so, read the file information in the channel directory, sort it, and traverse the storage files in the channel directory in all date directories in the root directory of the storage medium in turn, and finally All the stored files in the storage medium are arranged in descending order according to the time sequence to obtain the first directory file list.

The channel directory refers to a directory of files of different data types under the corresponding date directory.

After the step S2, it also includes:

S3. Determine whether the first directory file list changes after the target operation instruction is executed, and if so, update the first directory file list.

Wherein, after the user executes the corresponding target operation instruction, it is determined whether the first directory file list has changed. The first directory file listing is updated. For example, when the user's operation instruction is an add or delete instruction, the corresponding storage file has been stored or deleted. At this time, the first directory file list is changed. Therefore, the first directory file list will be updated; for another example, the user's operation instruction is: When downloading or searching for an instruction, no changes are sent to the storage file at this time, and therefore, the file list of the first directory is not updated.

Preferably, the step S2 specifically includes:

When the target operation instruction is an add instruction, the date attribute and data type of the added file are acquired, and the added file is stored in the channel directory corresponding to the data type of the date directory corresponding to the date attribute.

The process of adding files is shown in Figure 3. First, determine whether there is a date directory in the root directory of the storage medium. If not, create a date directory according to the current time. If so, determine whether there is a corresponding channel directory in the date directory. If not, create the corresponding channel directory of the added file. and store the added file in the channel directory; if so, directly store the added file in the channel directory.

Preferably, the step S2 further includes:

It is judged whether the file duration of the added file is greater than the preset duration, and if so, the added file is divided into multiple sub-added files, and the multiple sub-added files are named according to the order of adding time.

Among them, as shown in Figure 3, 30 minutes are used as the preset duration. If the duration of any added file is greater than the preset duration, a new sub-added file will be recreated to control the size of a single added file; The sub-added files are named according to the creation time, which is convenient for subsequent sorting.

Preferably, the step S2 specifically includes:

When the target operation instruction is a search instruction, the first directory file list is traversed, and the file information of the storage file corresponding to the search instruction is returned.

Wherein, when the user needs to find the required storage file, the user traverses the first directory file list to obtain the storage file, and returns the file information of the storage file to the user.

Preferably, the step S2 specifically includes:

When the target operation instruction is a deletion instruction, the storage file corresponding to the deletion instruction is deleted from the first directory file list.

Wherein, when the user needs to delete the corresponding storage file, the user traverses the first directory file list, finds the storage file, and deletes the storage file from the storage medium.

Preferably, the step S2 specifically includes:

When the target operation instruction is a download instruction, the first directory file list is traversed, and a storage file corresponding to the download instruction is sent to the user according to a preset communication protocol.

Wherein, when the user needs to download the required storage file, traverse the first directory file list to obtain the storage file, and send the storage file corresponding to the download instruction to the user according to a preset communication protocol. The preset communication protocol is a communication protocol commonly used for downloading in the art, and details are not described here.

Wherein, in addition to the above-mentioned adding, deleting, searching and downloading instructions, it may also include: marking instructions.

When the user's instruction is a marking instruction, the first directory file list is searched, the tag attribute of the storage file corresponding to the marking instruction is updated, and the storage file is backed up to an independent storage area in the storage medium to avoid automatic deletion.

Preferably, it also includes: judging whether the storage capacity of the storage medium reaches a first threshold, and if so, deleting the last n storage files in the first directory file list until the storage capacity of the storage medium is less than The first threshold, where n is a positive integer.

The first threshold means that the storage capacity of the storage medium reaches a preset value. For example, the first threshold may be 90%. At this time, when the storage capacity occupancy rate of the storage medium reaches 90%, the first directory file list will be Storage time ranks at the end of one or more storage files for deletion until storage capacity occupancy falls below 90%.

It should be noted that, the first threshold value can be changed according to requirements, and is not limited to the value mentioned in the embodiment of the present invention.

Preferably, the method further includes: judging whether the service life of the storage medium reaches a second threshold, and if so, sending early warning information to the user.

The second threshold refers to the service life of the storage medium (which may be, but is not limited to, a magnetic disk). For example, the second threshold may be 10%. At this time, when the service life of the storage medium is less than 10%, an early warning is sent to the user. information.

It should be noted that, the second threshold can be changed according to requirements, and is not limited to the values mentioned in the embodiments of the present invention.
