|Configuring policies / Data control policy|
You can exclude files and file types from data control by setting up exclusions in a data control rule.
To exclude a file or file type from data control, exclude it in a rule with the highest priority (that is, specifying the most restrictive action).
To exclude files or file types from data control:
You can use the wildcards * and ?
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.
