Here are some thoughts:
o Does the problem page reside in the "_folder" folder?
If not, then serverfilename="folder/filetest.txt"
wouldn't point to _folder/folder/filetest.txt and
there's your problem.
o Have you verified that NTFS permissions are correct?
Does the anonymous Web account (or whatever account you're
using) have Delete privileges?
o Are you sure you're closing the file when the Web page ends?
o How much time passes between creation of the file and the
attempt to delete it? If it's only a few seconds, IIS may be
caching the file-open state.
o Are you sure you've thought out the implications of two
visitors running this application at the same time? Could
they end up trying to use the same file at the same time?
To avoid this, you may need to use system-assigned temporary
file names, or file names based on the visitor's session ID.
Then, to clean up the per-visitor files, you delete them in
global.asa's Session_OnEnd vent and/or a timed process.
