You can also assign Retention Folder policies to FSA targets using a command-line interface.
The CLI executable is Enterprise Vault\RtnFolder.exe.
You can include wild cards when defining target volumes and final target folders only.
The following examples using wild cards are correct:
/Target:\\ServerA\C$*\MyFolder\AB* /Target:\\ServerA\C$*\MyFolder\A*B* /Target:\\ServerA\C$*\MyFolder\A*B
The following example is not correct, because wild cards can only be included in the volume name and final folder name:
/Target:\\ServerA\C$*\MyFol*der\AB*
