Copy files to an audio player and playing order
Hi, I have a digital recorder / player, a Sony PCM-M10. It can take FAT formated Micro SD cards. I can access them via USB, mount them and copy folders and files. However, there is one glitch: the order of the files. I call them 01_dada.wav, 02_ased.wav etc. ad hope it plays it in that order. The manual states: "If you have copied music files using your computer, those files may not be copied in order of copying because of the system limitations. If you copy a music file one by one to the PCM recorder, you can display and play back tracks in order of copying." So I copied the files after sorting them: find . -depth -print0 | sort -z | pax -wd0 | tar -xf - -C /mnt Still, the order is random. I wonder why.. My memory of FAT is blurry. During studies I "visited" floppy sectors to get deleted data back. If i am not mistaken, if a directory is new, it puts filename by filename in a directory list and references, one by one, although I am not familiar whether that changed with VFAT and long filenames. I may experiment with "real" copy one by one - directories first and then a kind of for f in `find . -type f`; do cp $f /mnt/$f; done or trying to figure out what changing the modification time does.. at the moment I am not sure why it's not working. Any ideas or experiences how to fix it? BTW: Besides of that I am very happy with the Sony PCM-M10. I have it on my HiFi at the moment and it has a crystal clear and full sound. Thanks Peter

Hi Peter I typed "fat directory order" into a search engine and with 5 seconds effort found this apparently related info: http://www.murraymoffatt.com/software-problem-0010.html I have no additional knowledge to offer you but I thought I might as well send it to you as you don't mention having done any searching yourself: I assume you sent this to luv-main because you are using a linux machine to copy the files? That page does emphasises other offtopic operating systems and non-linux filesystems, but it does include a couple of references to linux utilities and hopefully might provide you other useful insight into your problem.

Apart from not catering for embedded spaces in filenames, the 'find' here won't sort the files into a collation order. When copying sets of files from a single directory to an mp3 player, I just use a wildcard copy, since the wildcard will expand in collation order. Also, there's a program 'fatsort' in the package repositories which will do recursive directory sorting on FAT16 and FAT32, though I haven't tried it myself. Glenn -- sks-keyservers.net 0x6d656d65

Also, I notice that 'rsync -a' copies files in a sorted order (though I suspect this is just a side effect of the matching process; I haven't checked exactly what collation order it follows). That could be useful for transferring a hierarchy of folders onto your FAT based player. Glenn -- sks-keyservers.net 0x6d656d65
