- Go to .
- Click the File Attribute tab.

Not selected: The selected file types will be excluded.
-
Selected: The selected file types will be included.
-
- Select your preferred true file types.
- If a file type you want to include is not listed,
select File extensions and then type the file type’s
extension. Data Loss Prevention checks files with the specified extension but
does not check their true file types. Guidelines when specifying file
extensions:
-
You can include wildcards in extensions. Use a question mark (?) to represent a single character and an asterisk (*) to represent two or more characters. See the following examples:-
*.*m
matches the following files:ABC.dem
,ABC.prm
,ABC.sdcm
-*.m*r
matches the following files:ABC.mgdr
,ABC.mtp2r
,ABC.mdmr
-*.fm?
matches the following files:ABC.fme
,ABC.fml
,ABC.fmp
-
Be careful when adding an asterisk at the end of an extension as this might match parts of a file name and an unrelated extension. For example:
*.do*
matchesabc.doctor_john.jpg
andabc.donor12.pdf
. -
Use semicolons (;) to separate file extensions. There is no need to add a space after a semicolon.
- Type the minimum and maximum file sizes in bytes. Both file sizes must be whole numbers larger than zero.
- Click Save.
