Even though today's 2.5'' hard drives have generally reached the level of 20GB~40GB, they can accommodate a large number of digital audio and video channels, but because of the current intellectual property rights regulations, many The copyrighted digital video recorder is digitally copyrighted (DRM, Digital Rlghts Manage_〇, and will not be played again after a certain number of playbacks or after the playback period has elapsed. It must be re-paid for download after 13107092, so it will be used frequently. There are a lot of digital audio and video files that can no longer be used in the hard disk of the portable multimedia player, which causes a waste of storage space. Therefore, users often need to transfer the digital audio files that cannot be used again or the rest of the files that are not needed to be recycled. Space (commonly known as trash cans or resource recycling bins) to reduce waste of storage space. When the receiving space is full and you cannot delete the deleted file, you usually choose not to check the file in the recycling space and choose to completely remove the recycling space at one time. This is easy for users to delete the file by mistake, which will cause irreparable damage. Mistakes, especially the accidental deletion of certain particularly important business documents or unique private files, will be difficult to estimate. The recycling space associated with portable multimedia players in the prior art is a one-time thorough removal method. For the current erroneous deletion of files, it may not be able to provide a comprehensive and complete solution. Therefore, it is extremely urgent to provide a perfect recycling space protection mechanism. SUMMARY OF THE INVENTION The main object of the present invention is to provide a portable multimedia player. The protection mechanism of the memory recycling space is to use a warning message to remind the user that the reclaimed space has insufficient capacity, and can be combined with the expansion of the total capacity of the reclaimed space and the manual or automatic selection of the reclaimed space memory file in order to completely remove the method. Therefore, even if the user deletes the file by mistake It is still possible to save the erroneous deletion of files when the selection file of the collection space is completely removed, thereby preventing the user from accidentally deleting due to temporary observance. 7 1317092 The present invention relates to a recycling space of a portable multimedia player. The warning method is applicable to a portable multimedia player. The portable multimedia player includes an information storage space for storing files. The method for reclaiming space of the portable multimedia player includes: Setting a recycling space to store the deleted file; adjusting the total capacity of the recycling space; selecting at least one file to be removed, so that the file becomes at least one deleted file; comparing the amount of data of the deleted file with the capacity of the recycling space; And when the capacity of the recycling space is insufficient to accommodate the deleted files, a warning message is sent to inform the user that the capacity of the recycling space is insufficient. In order to make the person skilled in the art understand the purpose, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments, and with the accompanying drawings: FIG. 1 is a block diagram of a preferred embodiment of the present invention.

The portable multimedia player 1 includes an information storage space 2 To store electronic information. Please refer to FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6 and FIG. 7. Referring again to FIG. 1, FIG. 2 is a flow chart 1 and FIG. 3 is a schematic diagram of a preferred embodiment of the present invention. FIG. 4 is a flowchart of a preferred embodiment of the present invention, FIG. 5 is a flowchart of a preferred embodiment of the present invention, and FIG. 6 is a flowchart of the present invention. Flowchart 5 of the preferred embodiment, FIG. 7 is a flow chart 6 of a preferred embodiment of the present invention. The recycling space warning method of the portable 8 1317092 type multimedia player includes: checking whether the information storage space 2 has a recycling space 3 (S1), wherein the recycling space is used for storing the information stored in the information storage space 2 In addition to deleting the file 4 arbitrarily; if there is no recycling space in the information storage space 2, the recycling space 3 (S2) is set in the information storage space 2 to be stored by the information 'storage space 2' The file 4 is deleted arbitrarily; the total capacity of the recovery space 3 is adjusted according to the user's preference (S3). The adjustment method disclosed in the embodiment is one of the B of the total capacity of the information storage space. Recovering the total capacity of the space 3; however, the adjustment amount is preferably not more than the upper limit value set by the information storage space 2, and the upper limit of the adjustment amount set by the embodiment of the present invention is six of the total capacity of the information storage space 2. One of them is to maintain a larger file storage space; if the information storage space 2 has completed the setting of the recovery space 3, the process proceeds to step (S3) to adjust the total capacity of the collection space 3 according to the user's preference. Size. Selecting at least one file for removal, so that the selected file becomes • deleting the file (S10); comparing the total amount of data of the deleted file with the capacity of the recycling space 3, wherein the first comparison is the deletion Whether the total amount of data of the file is greater than or equal to the total capacity of the recovery space 3 (S11); if the total amount of data of the deleted files is greater than or equal to the total capacity of the recovery space 3, a warning message is sent to inform the user of the recycling The capacity of the space 3 is insufficient (S12); next, the user is asked whether the total capacity of the recovery space 3 can be expanded (S13). Before the total capacity of the recovery space 3 is expanded, the recovery space 3 can be checked by 9 1317092. Whether the total capacity can still be expanded. If the information storage space 2 cannot provide sufficient expansion space, if the information storage space 2 is full or the total capacity of the recovery space 3 has reached the upper limit set by the information storage space 2, If the recovery space 3 is unable to expand the total capacity, the user is informed that the total capacity of the recovery space 3 cannot be expanded. If the total capacity of the recovery space 3 is still expandable, then For the user to choose whether to expand the total capacity of the recycling space 3; if the total capacity of the recycling space 3 can still be expanded and the user chooses not to expand the total capacity of the recycling space 3, the user is informed and will be completely moved In addition to the deleted files (S14), if the total capacity of the recovery space 3 is still expandable and the user selects the expansion, the total capacity of the recovery space 3 is expanded (S15), so that the remaining capacity of the recovery space after expansion is sufficient Inserting the deleted files, and then proceeding to step (S27), wherein completely removing the data representing the files in the embodiment is completely eliminated from the information storage space 2, which is different from the embodiment. The removal in the description means that only the file is moved from the location space in the information storage space 2 to the collection space 3. If the total amount of data of the deleted files is less than the total φ capacity of the recovery space 3, it is checked whether the total amount of the deleted files is greater than or equal to the remaining capacity of the recovery space 3 (S20); If the total amount of data is less than the remaining capacity of the recovery space 3, the deleted files are placed in the recovery space 3 (S27); if the total amount of the deleted files is greater than or equal to the remaining capacity of the recovery space 3, then Sending a warning message to inform the user that the remaining capacity of the collection space 3 is insufficient (S21); subsequently, the user is asked whether to agree to expand the total capacity of the collection space 3 (S22); if the user agrees to expand the total capacity of the collection space 3 and the information * 1317092 If the storage space 2 still provides sufficient expansion space, start to expand the total capacity of the collection space 3 (S23), and return to the step (S20); if the user does not agree to expand the total capacity of the collection space 3, or the information The storage space 2 cannot provide sufficient expansion space. If the information storage space 2 is full or the total capacity of the recovery space 3 has reached the upper limit set by the information storage space 2, If the recovery space 3 cannot be expanded in total capacity, the user is asked whether to completely remove the file in the storage space 3 memory, thereby expanding the remaining capacity of the recovery space 3 (S24); if not, then The deleted files are completely removed directly (S25), and all processes are terminated; if so, φ the memory space of the recovery space 3 is completely removed, thereby expanding the remaining capacity of the recovery space 3 (S26), and then The deleted files are placed in the recycling space 3 (S27); wherein the method for completely removing the memory space of the recycling space 3 can be automatically removed by using an automatic selection method or a manual selection method. File. The automatic selection method can completely remove the files in the collection space 3 according to the time when the file is moved into the collection space 3 or the amount of the archive data, thereby achieving the purpose of expanding the remaining capacity of the collection space 3; _ Check whether the remaining capacity of the recovery space 3 reaches a preset value (S28), wherein the preset value can be adjusted according to the user's preference. The adjustment method disclosed in the embodiment is the total capacity of the recovery space 3. One tenth of the setting is set to the preset value; if the preset value is not reached, all processes are ended; if the preset value is reached, the user is warned that the remaining capacity of the recovery space is insufficient (S30); After the remaining capacity of the recovery space is insufficient (S30), the user is asked whether the total capacity of the recovery space 3 needs to be expanded (S31), and 11 1317092 can be used to check whether the total capacity of the recovery space 3 is still expandable; if the information is stored Space 2 cannot provide sufficient expansion space. If the information storage space 2 is full or the total capacity of the recovery space 3 has reached the upper limit set by the information storage space 2, If the recovery space 3 cannot expand the total capacity, the process proceeds to step (S35); if the total capacity of the recovery space 3 is still expandable and the user selects to expand the total capacity of the recovery space 3, the recovery is expanded. The total capacity of the space 3 (S32); subsequently, checking whether the remaining capacity of the recovery space 3 reaches the preset value after the deletion file is placed (S33), and if the preset value is not reached, the process ends; Up to the preset value, asking the user whether to continue to expand the total capacity of the collection space 3 (S34); if yes, returning to the above step (S32); if not, asking the user whether to expand a file of the memory of the collection space 3 Performing a complete removal to expand the remaining capacity of the recycling space 3 (S35); if the user agrees to expand the remaining capacity of the recycling space 3, if so, the memory space of the recycling space 3 is completely removed, thereby expanding the recycling Space 3 remaining capacity (S36), and all processes are ended; if not, that is, the user does not agree to expand the remaining capacity of the recovery space 3, a warning message is sent to inform the user that the recycling space 3 is empty Still less (S37), and ends all processes. In summary, the recovery space warning method of the portable multimedia player of the present invention sends a warning message to remind the user when the capacity of the recovery space reaches a preset value, thereby avoiding the situation that the remaining capacity of the recovery space is insufficient. Moreover, the present invention can be combined with expanding the total capacity of the reclaimed space to accommodate more deleted files, so as to prevent the user from completely eliminating the reclaimed space memory file due to insufficient capacity. In addition, the present invention can also be used to manually or automatically select a file to be completely cleared. Therefore, after the user deletes the file by mistake, the file in the collection space can be re-examined by manual or 12 1317092 automatic selection and thorough removal. Save the accidental deletion of files to prevent accidental deletion. Therefore, the present invention not only reminds the user that the remaining capacity of the recycling space is insufficient, expands the total capacity of the recycling space to accommodate more deleted files, and can re-examine the files contained in the recycling space to save the erroneous deletion of files, so the present invention is highly progressive.
