The ribbon tab Home contains the most commonly used actions and elements of TreeSize.

### Select directory for scan | Opens a dialog enabling you to select a target for scanning. This dialog allows to configure complex scan targets with just a few clicks. TreeSize will start scanning the selected path once the selection has been confirmed. You can also enter a path directly into the drive combo box in the toolbar.
### Stop | Stops the currently selected scan. This will abort the current scan process but not remove it from the Directory Tree. The Stop button also offers a drop-down menu with more options: •Stop: Stops the currently selected scan, even if it is already paused. •Pause: Pauses the currently selected scan, without aborting or stopping it. You can resume a paused scan later. •Resume: Resumes the currently selected paused scan.
### Refresh | Refreshes the currently selected scan. The Refresh button also offers a drop-down menu providing access to more specific options: •Refresh all scans: Using this option will trigger a full refresh for all scans of TreeSize. •Refresh selected folder: With this option, you can refresh the currently selected folder only. •Watch for file system changes: If you enable this option, TreeSize will keep track of the Windows change notifications and update the size information as well as several other information automatically. If you don't want the size information to change after the scan has finished, you should turn off "Automatic Updates". This option can be enabled or disabled for individual scans.
