Quick question regarding Exclusions and Wildcards...

One of our clients are running Sophos on their client PC's and on the server hosting our Software solution and Firebird database. We have a very big speed issue when our application is executed from a share on the server and where it then calls its own DLL's... Even a menu item that has a sub-item that points to a DLL takes about 10-20 seconds to show but it is almost instant when Sophos is disabled.

I am not on site and just need some clarification on wildcards and exclusions.

From the Sophos help document I know the following limitations:

• The wildcard ? can be used only in a filename or extension. It generally matches any single character. However, when used at the end of a filename or extension, it matches any single character or no characters. For example file??.txt matches file.txt, file1.txt and file12.txt but not file123.txt.
• The wildcard * can be used only in a filename or extension, in the form [filename].* or *.[extension]. For example, file*.txt, file.txt* and file.*txt are invalid.
• You can specify a folder and filename, and Sophos Anti-Virus excludes any folder and filename that match. For example
  logs\log.txt causes Sophos Anti-Virus to exclude log.txt in any folder called logs on any drive or share.

Seeing how very limited Sophos handles wildcards, I just need to know whether adding a file exclusion as folder\*.ext will work or will I need to create an folder\differentname.ext entry for every filename even if the ext is the same?

Thanks in advance
