However, since there are so many types of file extension types, I recommend you use *.exe with All File Types checked. For example - executables - there are many different types of executables, including self-executing. Using *.* with EXE file types does not leave room for files that are .exe's, but may be classified as something else, which I have seen before. Using *.exe with all types does. Hope I cleared things up instead of making them more confusing. Thank you, Holly Kipp Sybari Software, Inc.

So if you want to block all EXE programs, you put in a file name of *.* and a file type of EXE and it will block all EXE programs no matter what name or extension.<< This got me wondering if we have set up our filters the right way. The way we did it, we have wild-cards for each specific file type, in the File Names section, and for each one we have "All Types" checked under File Types. Then of course we have File Filter set to Enabled, and Action set to "Delete: Remove Contents". For instance, to block executables (we hope) we have a filter for "*.exe" / "All Types" / "Enabled" / "Delete: Remove Contents". Are we doing it wrong? What's the difference between filtering, e.g. "*.exe" / "All Types", vs "*.*" / File Type = Exefile? Thanks in advance for your help. Regards, Bob Peitzke Information Systems Manager Sander A.
