Folder Size Filter

First you have to choose whether the items that match the filter will be included or excluded from the results. Then set filtering based on Name, Size, Attributes and File age. At the bottom of the dialog choose if the filter should match Files, Folders or both. Additional information is available on our Folder Sizes FAQ page.

Please note that the filter button (The one with the funnel icon) is a two state button. If you press it the filter dialog is displayed in order to setup a new filtering rule. If you exit the dialog with OK it will remain down denoting that filtering is applied. In order to disable the filter press the button again and it will go up and disable filtering. In order to enable the filter or setup a new one pressing the button again will show the filter settings dialog.

2) In order to scan an entire drive select it from the drop-down list and press the Scan button.
3) In order to scan a single folder press the Scan Folder button. You will be prompted to choose a folder.
4) Use the "Select Multiple Locations" button to scan multiple locations simultaneously. If the locations are on separate physical drives, this will reduce the scan time dramatically.
