Overview of Find and Remove Junk Files wizard
On the Options screen, you designate other general options
Ignore files that have been used within the last [X] days. Select this option to skip files that were accessed recently. You can enter from 1 to 30 days.
Ignore read-only and system files. Windows and other applications sometimes mark files with read-only or system attributes. These attributes usually designate an important and necessary file that should not be removed.
The check box is selected as a default.
Ignore files currently being used by an associated application. Removing a file currently used by an application can cause unexpected or hazardous results. Although System Mechanic automatically prevents removing in-use files, if an item name matches the configured search criteria, this option prevents them from being listed when a scan is performed.
The check box is selected as a default.
After making selections, click Next to run the search.
