why is File.Exists() so slow...?

[Guest]

I'm developing a .Net app on a Pocket PC and my app has access to several
thousand files and I wanted to test file existance before passing onto a DLL,
but it seems really slow to check file existance - anyone any ideas why or a
faster .Net-based solution to do the same thing?
Thanks

Is it checking for just one file, or numerous files?
If latter, speed it up by loading all file names using Directory.GetFiles()
and iterationg through them in memory.
