Block the file. Select this if you want Enterprise Vault to block files that are matched by this rule.

Allow the file. Select this if you want Enterprise Vault to allow files that are matched by this rule.

Check file content. Select this to make Enterprise Vault scan the contents of files, rather than relying on file types. This would catch, for example, a .MP3 file that had been renamed to .TXT.

Note that choosing to check file content can also affect the file groups that you choose to block or allow on the File Groups tab. For example, if you choose to block *.JPEG and content checking is enabled, this would have the effect of blocking all JPEG files. If you also chose to allow *.JPG a file type, such files would still be blocked because their contents would reveal them to be JPEG files.

Scan inside archive. Select this to scan the contents of files within compressed files such as ZIP files. Use Depth level to scan

Selecting Scan inside archive may have some impact on performance.
