The file path is the source path of the media data file.

[0059] Referring to FIG. 2, in the second embodiment of the present invention, the to-be-loaded media data file is derived from an external device, and the step S1 includes:

[0060] S10: Scan the storage folder of the foregoing external device step by step.

[0061] The step-by-step scanning in this step includes comprehensive scanning from the total folder to the sub-folders of each level in order to ensure that any required media data files are not missed. The storage folder of the media data file refers to the folder in which the media data file was not originally loaded before the in-vehicle system.

[0062] S11: Identify a file suffix name of all the media data files in the storage folder.

[0063] In this embodiment, the file type of the media data file is classified and classified by identifying the file suffix name. The file extensions include: image file suffixes, such as BMP (bitmap), JPG, JPEG. PN G, GIF, etc.; audio file suffixes, such as MP3, OGG, WAV, APE, CDA, AU, MI DI, MAC , AAC, etc.; video file suffixes, such as RMVB, WMV, ASF, AVI, MPG, MKV, MP4, DVD, OGM, MOV, MPEG2, MPEG4, etc.

[0064] S12: Differentiating the file type of the media data file according to the file suffix name.

In this embodiment, the classification is performed according to the file suffix name of the media data file, so as to classify each media data file, and improve the file type classification accuracy of the media data file.
