Create video clip playlist export to xml5/19/2023 ![]() It appears that this file has as its 'magic bytes' (hex) 68 64 66 6D, which spell "hdfm" in ASCII, at the start of the file. ![]() Since this binary version is the only one iTunes actually reads, if it is deleted or corrupted iTunes will rebuild it solely from the data present in the individual audio/video files themselves, losing all other metadata and playlists it will not load this information from the XML file. It's changed between iTunes versions before, and probably will again all in all, it's better to use the XML version documented below if you wish to examine an iTunes collection or export playlists. The format is proprietary and undocumented, and there is evidence that Apple intentionally obfuscates it to make it difficult for anybody else to use the file directly, but there have still been efforts to figure out the format with some success (see external links below). This is where iTunes gets the information it displays and uses, and it is updated continuously with any changes such as new tracks added or updated play counts every time a track is played. The file actually used by iTunes is the binary one, named iTunes l (or iTunes Music l in early versions it keeps the original filename from your system even when you upgrade). When you make a change to metadata (e.g., the title or artist of a song), the change will be immediately written to both versions of the library file, as well as to the song file itself if it is in a format that supports embedded metadata. There may be other files related to the library there as well, such as automatically-generated backups saved at various times (the "Previous iTunes Libraries" subdirectory will usually have a whole bunch of them), but these two are the ones in direct immediate use. ![]() They are both found in the iTunes main directory, which in turn is generally located directly beneath the "Music" directory/folder of the particular user (a location which varies by version of Windows or MacOS). The two different library files are the binary (.itl) file, and the text-based (.xml) file. This means that iTunes puts all of its eggs in one basket, though it then proceeds to duplicate them in a second basket of a different design. Also, all of the playlists are stored within the single music-library file, instead of having separate files. This includes metadata such as artists and titles, dates of when each track was added to the collection and when it was last played, the count of how many times each track has been played, and other information. The iTunes Music Library (or simply "iTunes Library" since it now includes things other than music as well) keeps track of all the information Apple's iTunes program knows about the songs, videos, podcasts, etc., which are part of a user's collection.
