Same as with sets, if the file set is not used in the rules, it can be deleted.
To delete a File Set, go to the account settings > select the File sets tab > find the required file set > go to the file set menu > select Delete. You can delete the file sets of the selected account as well as the file sets of its child accounts.
Clicking Delete will redirect you to the Remove Set page. If the file set is not used in the rule(-s), the corresponding message will be displayed. Click Confirm to complete the file set deletion.
If the file set is used in the rule(-s), the option to delete it won’t be available and the corresponding message will be displayed.
