Among them, the above-mentioned storage medium can be a disk, an optical disk, a read-only memory (ROM) or a random access memory (RAM), etc.

[0043] Based on the above hardware structure, an embodiment of the file acquisition method of the present invention is proposed.

[0044] Reference Figure 2 , Figure 2 This is a flow chart of a first embodiment of a method for acquiring a file according to the present invention, which is used in a terminal device; the method comprises the following steps:

[0045] Step S11: receiving a file acquisition instruction.

[0046] It should be noted that the file acquisition instruction can be a file acquisition instruction input by the user to the file acquisition program through the input module on the terminal device, or it can be a file acquisition instruction sent by other mobile devices connected to the terminal device (for example, a remote control or a smart phone, etc.), wherein the input module can be a voice input module or a keyboard input module, and there is no limitation here.

[0047] It can be understood that, for a file acquisition instruction, the file acquisition instruction may include acquiring a first type of file, and may also include acquiring a second type of file and a third type of file. In this case, the first type of file, the second type of file and the third type of file need to be acquired respectively, and the acquisition method refers to the first type of file acquisition method described below, that is, first determine whether it exists in the memory, and if so, directly acquire it; if not, acquire it in the local storage.

[0048] Step S12: Based on the file acquisition instruction, a first type of file is acquired from the memory of the terminal device; wherein at least a plurality of first type of files are stored in the memory of the terminal device, the first type of files meets a first preset condition, and the memory usage of the terminal device is less than a memory threshold.

[0049] It should be noted that the memory threshold can be set by the user according to his own needs to prevent the memory usage from being too high. Preferably, the memory threshold is 75%. The user can set the memory threshold to other values ​​according to his own needs.

[0050] When receiving a file acquisition instruction, in order to quickly acquire the file, a part of the files to be acquired in the file acquisition instruction (a plurality of first type files), that is, a part of the first type files are stored in the memory, and the other part is only stored in the local storage (not in the memory), so that the terminal device can quickly acquire the first type of files stored in the memory. At this time, the memory usage rate of the terminal device is low, lower than the memory threshold, and meets the first preset condition. The memory threshold can be a value set by the user according to his own needs. Preferably, the memory threshold is 60%.

[0051] Among them, the first type of file can be a video, an original picture or a thumbnail, etc., and the file that meets the first preset condition can be that the file occupies less memory and has a higher usage rate. Among them, the small memory occupancy can be limited by the file occupying less than the file threshold, and the high usage rate can be limited by the number of acquisitions exceeding the preset number. The specific file threshold and preset number can be set by the user according to his own needs and are no longer restricted here.

[0052] Furthermore, the first type of file in the memory is a file associated with a soft reference; a file associated with a soft reference indicates that the file can be deleted when the memory usage of the terminal device is greater than the memory threshold and the file does not meet the first preset condition. As the terminal device runs, there will be more and more cached files in the memory, and there may also be more and more first type files. At this time, it is necessary to delete some of the first type of files according to the memory usage, that is, associate the first type of files with soft references so that the first type of files associated with soft references can be deleted to free up memory space and reduce the memory usage to not exceed the memory threshold.

[0053] For example, when file A is associated with a soft reference and is stored in memory, when the memory usage is greater than the memory threshold and the file does not meet the first preset condition, file A will be deleted to ensure that the memory usage does not exceed the memory threshold and the memory usage is low.

[0054] In specific applications, picture files can be associated as soft references, and video files with playback records can also be associated as soft references. Preferably, when a video file has a playback record, the thumbnail corresponding to the video file is associated as a soft reference, that is, the first type of file includes picture files, videos with playback records, and thumbnails corresponding to videos with playback records, etc.

[0055] It is understandable that when images and videos are cached in memory, they can be thumbnails corresponding to the cached files to save memory space. The thumbnails can be preview thumbnails of images, cover screenshots of videos, or thumbnails of a certain video frame of a video.

[0056] Furthermore, a second type of file is also stored in the memory of the terminal device, and the second type of file in the memory is associated with a weak reference; the file associated with the weak reference indicates that the file can be deleted after the terminal device runs for a preset time interval.

[0057] The terminal device scans the memory at a preset time interval, and when a second type of file associated with a soft reference is scanned, at this time, regardless of whether the specific value of the memory usage rate exceeds the memory threshold, the associated weakly referenced file cached in the memory needs to be deleted. The preset time interval can be a time interval set by the user according to demand, and the present invention does not limit it.

[0058] Specifically, the second type of file may be a video file for which no playback record exists, or may be a thumbnail corresponding to a video file for which no playback record exists.

[0059] In one embodiment, the thumbnails corresponding to video files, picture files and text files can be thumbnails generated by the terminal device itself; when the file is a picture file, the thumbnail can be a thumbnail of the picture file; when the file is a video file, the thumbnail can be the cover of the video file or a certain video frame; when the file is a text file, the thumbnail can be a summary of the text on the home page of the text file, etc.

[0060] Furthermore, a third type of file is stored in the memory of the terminal device, and the third type of file in the memory is associated with a strong reference; a file associated with a strong reference indicates that the file cannot be deleted.

[0061] Usually, text files occupy less space, and most of them are necessary files for system operation and cannot be cleaned up. Associating them with strong references will not cause the memory usage to be too high, that is, the memory usage rate will not exceed the memory threshold.

[0062] Furthermore, the step of obtaining a first type of file from the memory of the terminal device based on the file acquisition instruction includes: based on the file acquisition instruction, checking whether the first type of file exists in the memory of the terminal device; if not, obtaining the first type of file from the local memory of the terminal device and caching the first type of file in the memory; if so, obtaining the first type of file from the memory of the terminal device.

[0063] It should be noted that when it is necessary to obtain the first type of file, it does not necessarily mean that the file is cached in the memory. Only part of the first type of file may be stored in the memory. Therefore, it is necessary to determine whether the first type of file exists in the memory. If so, it is directly obtained in the memory. If not, it is necessary to obtain the first type of file in the local memory and cache the first type of file obtained from the local memory into the memory, so that the first type of file can be quickly obtained in the memory when the file is obtained next time.

[0064] It is understandable that when acquiring the first type of file, the local storage and the memory may be traversed to acquire the first type of file, that is, a portion of the first type of file may be acquired in the memory, and another portion of the first type of file may be acquired in the local storage. Similarly, when the file acquisition instruction also includes acquiring the second type of file and the third type of file, it is necessary to traverse the memory and the preset storage to acquire the second type of file and the third type of file, respectively.

[0065] Furthermore, the memory of the terminal device includes a cache sequence, in which the first type of file is cached; if so, the step of obtaining the first type of file from the memory of the terminal device includes: if so, obtaining the first type of file that meets the second preset condition from the cache sequence.

[0066] It should be noted that the cache sequence can be an arrangement sequence of files, and the cache sequence can include first type files, second type files, and third type files, etc. The files in the cache sequence have an arrangement order, which can be an order from high to low in terms of the number of file acquisitions, or an order from low to high in terms of the number of file acquisitions, or an order from high to low in terms of file size, etc. The present invention does not impose any limitation on this.

[0067] Among them, the second preset condition can be a condition set by the user according to his own needs. For example, when the arrangement order of files in the cache sequence is from high to low order of file acquisition times, the second preset condition can be the N first type files at the front end of the cache sequence; when the arrangement order of files in the cache sequence is from high to low order of file acquisition size, the second preset condition can be the N first type files at the end of the cache sequence, etc.

[0068] Furthermore, the step of obtaining the first type of file that meets the second preset condition from the cache sequence includes: obtaining the first type of file at the front end of the cache sequence; wherein the front end of the cache sequence includes the first type of file with the highest acquisition rate. In this embodiment, the arrangement order of the files in the cache sequence is from high to low order of the number of file acquisitions. The file with the highest acquisition rate is the first type of file with the most acquisitions. At this time, the user satisfaction of the first type of file obtained is high and it is more in line with the user's request to obtain the file. It can be understood that the acquisition rate of a file is the ratio of the number of times the file is acquired to the total number of times the file is acquired. At the same time, the total number of times the file is acquired is a constant. If the file acquisition rate of a file is the largest, then the file has the largest number of file acquisitions.

[0069] The technical solution of this embodiment adopts a file acquisition method for a terminal device, the method comprising the following steps: receiving a file acquisition instruction; based on the file acquisition instruction, acquiring a first type of file from the memory of the terminal device; wherein at least a plurality of first type of files are stored in the memory of the terminal device, the first type of files meet a first preset condition, and the memory usage rate of the terminal device is less than a memory threshold. Since the first type of files stored in the memory for acquisition meet the first preset condition, by setting the first preset condition, it can be ensured that the space occupied by the memory is effectively controlled so that the memory usage rate of the terminal device is less than the memory threshold, thus solving the technical problem of excessive memory occupation and achieving the technical effect of low memory occupation when the terminal device acquires files.
