We have been experiencing these deleted or corrupt .20i files for a number of years on our network version of ProSeries. ProSeries help desk claims there are no issues with their program and it must be our anti-virus program. We followed their instructions to the letter and still we keep running across many deleted/corrupt tax returns. It is not our anti-virus because if it was we should see the files in the quarantine folder. Instead I will find a file that looks similar to ~274krh6.  If you rename the file or try to manually search and open it, it will be at least a fragment of the deleted tax return.

Has anyone experienced anything similar or have any suggestions?
