I did before and I just did it again.

The problem is that it is overwriting the .exe0 files as if they were .exe.
That is an LFN problem in 2.01.

For example:

1. Make a text file, x.abc0
2. open the file with Edit x.abc0
3. While in Edit, do a FileSaveAs with the name x.abc
4. Exit Edit

Both x.abc0 and x.abc exist, so it is not a Win 95 problem.
