Patterns

If you need information about e.g. certain file types only, you can specify a filter here. You may use multiple filters separated by semicolons. So if you for example want to see how much space your executable files and their libraries occupy, use the filter "*.exe *.dll" here. If you want to include all files leave the field blank. You can also specify a fragment of a path, e.g. "*\My Videos\*", this can be useful for getting the size of only certain folders.
Changing this option will make a rescan necessary. This options will not be saved when you exit TreeSize Professional in order to avoid wrong results when using it the next time.

Include only Files Created in the Past XX Days

This option is quite self-explanatory and can be useful to calculate the size of backups or to identify "heavy growing" folders.

Include only Files with Archive Bit Set

This option is useful if you are interested in the size of a backup that will be performed on the basis of the Windows Archive Bit.

Excludes

If you want to exclude certain files or folders from scanning, add matching patterns here. A pattern may look like "Windows" or "*.tmp". Files or folders matching one of the specified patterns will be ignored during a scan.

Exclude Offline Files

This option allows to exclude files that are marked as Offline. Offline files are often not physically present on the disk or are only cached temporarily on the local disk.
