See my last post for the technical explanations.
If I'm guessing correctly, you are running an NT server with IIS? On the
first page of your application you create a file that the user can then
download? With some subsequent page request, you then delete the file?
However, the file still appears to be in the folder tree and a new one with
the same name cannot be written for some period of time.
If this is the case, then it should not make any difference whether or not
the user is "opening" or "saving" the file. What your probably experiencing
is just the coincidental timing of your requests and the cache scavenger. I
would recommend naming the files uniquely and running your own separate
scheduled task that deletes files nightly that are older than so many hours.
If this is not the case, then you really need to give us a better idea of
what OS, Web server, version of ColdFusion, etc. you are running, as well as
the logic behind the application.

This is great help and I appreciate all this feedback.
Is there an answer to my second question... I think this is an issue if
someone tries to OPEN the file instead of SAVING it. So the second
question is is there a way to force someone to DOWNLOAD the file instead of
opening it?
This would also help me.

Keep in mind that though this eliminates most problems, the issue will
still persist. The best way to solve the problem is to use the CFLOCK tag.

You are encountering file locking errors. The write is trying to begin
before the delete has released it's lock on the file. When writing and
deleting, I always rename the file first, then delete the renamed file.
Same for the write. Write to a temp file, then once the write is complete,
rename that to it's proper name.
