Issue/Introduction:

Can a regular expression be used to only find a file name?

Resolution:

Symantec DLP supports regular expressions for content matching, not file name pattern matching.

Symantec DLP supports DOS pattern matching expressions for file names.

* - Any number of characters
? - Any one character, or none
. - Literal match

For example, the pattern 'c:\TR*.zip' will match every file whose path starts with 'c:\TR', followed by any combination of characters, and ending with '.zip'."

The pattern '*' matches any combination of characters. This includes matching against text which contains no characters, so 'a*t' matches both 'act' and 'at'."

NOTE: TR*.zip will match nothing because it doesn't start with a share or local drive specification.

To match any zip file in the share being scanned beginning with TR and having a file name length of 2 to 5 characters, the syntax would be:

*\TR???.zip

(One ? for each character it is meant to represent)
