2 is a flowchart illustrating a file management method of a portable electronic device according to a specific embodiment of the present invention in detail.
As shown in Fig. 2, the file management method of the portable electronic device according to the present invention starts from the step of storing the reproduction record of the original file (S100). At this time, the reproduction record of the original file is based on the frequency of the reproduction of the file within the set period, the frequency of reproduction of all the files and the frequency of reproduction of each file, the frequency of reproduction of the entire file after the file is stored in the portable electronic device. A ratio of the reproduction frequency of each of the files, and the like.
Next, the remaining capacity of the portable electronic device storage memory is recognized (S110). Recognition of the remaining capacity of the storage memory is for setting a criterion for determining whether the file is compressed. That is, whether or not the file is compressed is determined according to the reproduction record including the reproduction frequency of the original file within the set period from the last reproduction time of the portable electronic device or the last power supply termination.
Subsequently, a set value for a period which becomes a reference for determining the file compression is designated according to the remaining capacity of the storage memory (S120). At this time, the setting value for the period which is the reference for the file compression determination is set longer as the remaining capacity of the storage memory becomes larger. This is because, when the storage capacity of the storage memory is large, it is less necessary to compress a file having a low playback frequency in order to efficiently manage the storage memory. On the other hand, if the remaining capacity of the storage memory is small, it is possible to manage the storage memory efficiently by setting a short period of time for compressing a file having a low playback frequency, leaving only the file having a high playback frequency recently and compressing the remaining files. To do this.
Next, it is determined whether or not an original file having no playback record exists within the set period (S130). In this case, if there is no original file without playback record within the set period, step 140 is performed. If there is no original file without playback record within the set period, file management of the portable electronic device according to the present invention is performed. Terminate the method.
Subsequently, if it is determined in step 130 that there is an original file having no playback record within the set period, a compressed file is generated (S140).
Next, the generated compressed file is classified according to the file format of the original file, stored in the nonvolatile memory, and the original file is deleted (S150). This classifies and stores the compressed file according to the file format of the original file, so that the user can easily search or play the compressed file when the user wants to search or play the compressed file. In order to secure the space of the storage memory by deleting the original file.
Next, it is determined whether there is a user input for playing a file (S160). In this case, if there is a user input for file reproduction, step 170 is performed. If there is no user input for file reproduction, the file management method of the portable electronic device according to the present invention is terminated.
Subsequently, when there is a user input for file reproduction in operation 160, the decompressed file is stored in the nonvolatile memory and the compressed file is stored in the volatile memory (S170). This is to use the stored compressed file without having to perform the compression process again if the user wants to delete the restored file and save the restored file again in the state of the compressed file before powering off the portable electronic device. In addition, when a user stores the restored file and deletes the compressed file, the compressed file may be deleted by shutting down the power of the portable electronic device.
3 is a flowchart illustrating a file management method of a portable electronic device according to another embodiment of the present invention in detail.
As shown in Fig. 3, the file management method of the portable electronic device according to the present invention starts from the step of storing the reproduction record of the original file (S200). At this time, the reproduction record of the original file is based on the frequency of the reproduction of the file within the set period, the frequency of reproduction of all the files and the frequency of reproduction of each file, the frequency of reproduction of the entire file after the file is stored in the portable electronic device. A ratio of the reproduction frequency of each of the files, and the like.
Next, the latest playback frequency of the original file is calculated (S210). In this case, the latest playback frequency of the original file is calculated by calculating the frequency at which the original file is played back within a set period from the last playback time or the last power-off time of the portable electronic device. This is to determine to compress the file.
Subsequently, it is determined whether there is an original file having a recent reproduction frequency lower than the set standard (S220). At this time, if there is an original file having a recent reproduction frequency less than the set standard, step 230 is performed. On the other hand, if there is no original file having a recent reproduction frequency less than the set standard, the file management method of the portable electronic device according to the present invention is terminated.
Next, as a result of the determination in step 220, if there is an original file having a recent reproduction frequency less than the set standard, a compressed file is generated (S230).
Subsequently, the generated compressed file is classified according to the file format of the original file, stored in the nonvolatile memory, and the original file is deleted (S240). This classifies and stores the compressed file according to the file format of the original file, so that a user can easily search or play the compressed file, and deletes the original file after the compressed file is created to save space in the storage memory. To secure.
Next, it is determined whether there is a user input for playing a file (S250). In this case, if there is a user input for file reproduction, step 260 is performed. If there is no user input for file reproduction, the file management method of the portable electronic device according to the present invention is terminated.
Subsequently, when there is a user input for file reproduction in step 250, the decompressed file is stored in the nonvolatile memory and the compressed file is stored in the volatile memory (S260). This is to use the stored compressed file without having to perform the compression process again if the user wants to delete the restored file and save the restored file again in the state of the compressed file before powering off the portable electronic device. In addition, when a user stores the restored file and deletes the compressed file, the compressed file may be deleted by shutting down the power of the portable electronic device.
4 is a flowchart illustrating a file management method of a portable electronic device according to another embodiment of the present invention in detail.
As shown in Fig. 4, the file management method of the portable electronic device according to the present invention starts from the step of storing the reproduction record of the original file (S300). At this time, the reproduction record of the original file is based on the frequency of the reproduction of the file within the set period, the frequency of reproduction of all the files and the frequency of reproduction of each file, the frequency of reproduction of the entire file after the file is stored in the portable electronic device. A ratio of the reproduction frequency of each of the files, and the like.
Next, the ratio of the reproduction frequency of the original file to the reproduction frequency of the entire file is calculated (S310). That is, the ratio of the sum of the reproduction frequencies of each of the files stored in the portable electronic device to the reproduction frequency value of the specific file may be calculated to determine that the original file is compressed when the calculated ratio is less than the set criterion.
Subsequently, it is determined whether there is an original file whose calculated ratio is less than a set criterion (S320). In this case, if there is an original file whose calculated ratio is less than a setting criterion, step 330 is performed. On the other hand, if there is no original file whose calculated ratio is less than a setting criterion, the file management method of the portable electronic device according to the present invention is terminated.
Next, as a result of the determination in step 320, if there is an original file whose calculated ratio is less than a setting criterion, a compressed file is generated (S330).
Subsequently, the generated compressed file is classified according to the file format of the original file, stored in the nonvolatile memory, and the original file is deleted (S340). This classifies and stores the compressed file according to the file format of the original file, so that a user can easily search or play the compressed file, and deletes the original file after the compressed file is created to save space in the storage memory. To secure.
Next, it is determined whether there is a user input for playing a file (S350). In this case, if there is a user input for file reproduction, step 360 is performed. If there is no user input for file reproduction, the file management method of the portable electronic device according to the present invention is terminated.
Subsequently, when there is a user input for file reproduction in operation 350, the decompressed file is stored in the nonvolatile memory and the compressed file is stored in the volatile memory (S360). This is to use the stored compressed file without having to perform the compression process again if the user wants to delete the restored file and save it again in the state of the compressed file before powering off the portable electronic device. In addition, when a user stores the restored file and deletes the compressed file, the compressed file may be deleted by shutting down the power of the portable electronic device.
