The TreeSize Professional File Search can be started through the Windows "Start" menu or the 13:00 "File Search" menu and allows you to search for big, old and temporary files. You will find the following tabs on the top of the window:
Biggest Files |
This page allows to search for the biggest files on your hard disk. You can specify a minimum size in kilobytes or megabytes. All files larger than this value will be shown in the list. |
Oldest Files |
This page allows you to search for files that have not been changed or accessed since a certain date. You can limit the search to entire folders. In this case only folders will be listed in which all files match the search criteria. This allows you to identify branches of the file system that are not in use any more. |
Temporary Files |
This page allows you to search for temporary files. Use the Configure button to customize the settings of the Temporary File Search. |
Internet Files |
This page allows you to search for temporary internet files like the files in the cache of the browsers Netscape Navigator and Internet Explorer. The search for temporary internet files can be automated with the command line option /SEARCH:Internet. |
Duplicate Files |
This page lists files which are on your disk more than once. You can choose if duplicates should be indicated by equal name, size and last change date, or by a compare of the md5 checksum of their content. Comparing the file content provides more accurate results, but the search will take longer. A minimum size speeds up the compiling of the list and prevents you from looking through many small files. A check box allows to control whether or not the exclude filter should be used. The context menu offers the possibility to replace duplicate files with hard links. |
Custom Search |
This page allows you to define a fully customizable file search. You can filter by filename, date, size, attributes and owner. |
Scan Options |
Here you can choose which drives and which of the above search types will be included in the search. You can add additional paths to the list by pressing the button below the list. All checked drives will be included in the search. Network drives are only supported in the Professional Edition. |
You will find the following buttons on the right side of the window:
Start |
This button will start the search. You can now already look at the partial search results by selecting one of the tabs. You will hear an acoustical signal when the search is finished. |
Stop |
Stops the currently running search |
Save Results |
This button allows you to save the search result of the currently active search type to a text or CSV file. The save dialog has an option to save all result lists (instead of the active one only), and an option to save the checked files only. Only the currently visible columns will be saved. |
Move Checked |
This button allows you to move all files in the lists which are check-marked to the left of their file name to a position in the file system that you may specify. If you choose a file system location all files will be moved there under preservation of the file system structure. You may also move the checked files to a ZIP file. Optionally all performed operations can be written to a log file. TIP: You can easily check a group of files by keeping the space bar pressed or by selecting multiple files with the Shift or Ctrl key and then use the context menu. |
Deduplicate Checked |
This button is only visible on the "Duplicate Files" tab. It replaces all checked duplicates with links to the same file. If the files are on the same partition, then all files will be hardlinks to the same content. If creation of a hardlink is not possible, a symbolic link is used under Windows Vista and later. If this is not possible too, a Windows shortcut will be created instead as fallback. |
With the File Search Menu items you can save and load your search settings (File menu), start and abort searches (Search menu) or customize the information shown in the result lists (View Options).
