Determine Icons based on File Extension onl

If this option is turned on, then TreeSize Professional uses the default icon for files based on the file extension only. This is much faster, especially on network drives, because Windows opens many file types in order to see if there are any icons inside. By default, this option is turned on.

Different Colors for Compressed Files and Folders        

If this option is turned on, compressed files on an NTFS volume are shown in a blue color. Folders that are partially compressed will have a dark blue color, files and folders that are entirely compressed will show up in a light blue color. For more information on file based compression see Notes on NTFS.

Show Folders containing Paths >255 chars in red

Folders that contain objects which have a path that exceeds 255 characters will be shown in red color. This is useful for finding file system structures that exceed the Windows MAX_PATH constant; many tools and the .NET framework have problems with these long paths. Using the custom search of the TreeSize Professional File Search you also can search for such files.

Show Long Tooltips in the Tree

If this option is active a tool tip window with detailed information will be shown if the mouse cursor pauses over a folder for a while. This is useful if you want to take a look at some detail information of a folder without switching to the Details tab.

Show Gradient Bars in Directory Tree

If this option is active, below a folder in the directory tree now a gradient bar is shown that indicates the size of the folder in relation to the entire scanned file system tree.

Show Time with Date Values

This option allows you to decide if time values should be shown with the last access, last modified and the creation date.

Automatically Update Right Pane During Scanning

If this option is turned on the right pane of the main window will be updated from time to time. This allows you for example to watch the bars of a chart growing while scanning large drives. Use the drag bar to set the interval of the updates.

Number of Folders in the Recently Used list

Adjust the number of recently scanned folders that TreeSize Professional should remember for quick access in the the pull-down box in the toolbar.

Bold Factor

If the size of a folder is greater than the set percentage or absolute value of the complete size of the scanned folder, the folder label will be shown bold. This allows you to quickly find the largest folders. If you don't want bold folder labels, choose "100%".

Use bold Text and Colors for Printed Reports too

Use this checkbox to define if the text formattings like bold (see above) or the colors when comparing scans should be applied to printed reports too.
