Hifiman 602 will not recognize flac files ( # 2 thread)

I have a windows xp system.  I have used the Exact Audio Copy software to create flac files from my cds.  When I hook up the usb cable to transfer these files to the 602 or use a memory card to transfer the files to the 602 nothing happens.  The 602 will not accept the files, the screen says "No File".  What exactly do I have to do to get my computer to work with the 602?  I have not been able to get any information or figure this problem out.  Hifiman techs have been no help and there is nothing on Google I have found yet.  I have been able to play these files on Mediamonkey.  I can't believe somebody else has not run into this problem, but if they have, there is no record on the internet.  Please help.

I have spent the last month scouring the net for information on how to solve this problem, returning the 602 and buying a Colorfly C4k (for half the price of the 602).  I finally tryed something simple I had read about elsewhere on similar forums and it worked.  The reason the flac files will not transfer is the file extension is too long by one letter.  All you have to do after you create the flac file is to rename the file and delete the c on the end of .flac making it .fla.  This worked on the C4k and probably would have worked on the 602.  Flac files take up more space but sound a lot better than mp3 files.  Give it a try if your player will accept flac music files.
