File Limit Per Directory in Windows CE?

Hello,

I was wondering if anybody has any information about this issue. I've run into a problem where at around 1,000 files within a directory, no more files can be written out (to the directory in question).  When removing the compact flash and putting it in a SanDisk reader at my PC, there seems to be no problem at all.  This problem has been replicated with a variety of compact flash disks (Type I and II/CF+) and occurs on WinCE .NET v4.1 and v4.2.  The number isn't exact.  Sometimes it is 995.  Another time it will be 1045, 1024, or 998, etc.  But, it does seem to occur frequently @ ~1,000 files.  I haven't found any documented issues of this type, so I would greatly appreciate any information that anybody might have.

OS: Windows CE .NET (4.1 & 4.2)
Media: Compact flash type I (SanDisk, FujiDisk, Memorex), type II (Hitachi Microdrive)
Board: ARCOM GX1, ARCOM Viper

Again, any help would be greatly appreciated.

Thanks
