• Defragger for all reachable drives under Windows NT(SP4)/2K/XP/Vista, works on removable disks too
• finds all system files, such as MFT, Re-parse points, bitmaps and attribute lists
• one of the main goals: search and find files and their position; therefore sometimes slower in redrawing ’cause of locking in huge directory-trees
• configurable blocksize, file-sizelimit, large-file-marks
• drive-information, cluster-viewer, file-search, single-file defrag (all in one window)
• data-corruption nearly impossible through 100% use of Windows-Defrag-API
• not movable: directories(FAT), locked files(page-, hibernate- and other systemfiles are locked on a running system; solution: boot from CD BartPE or use PageDefrag).

This is the main purpose of Disk Triage. It is a specialized utility that sizes and analyses any directory you choose. It presents the sizing information to you using a powerful Tree View, Graphs and Reports. DiskTriage also provides the ability to export the gathered data to Excel and to save the sizing information to a Database and/or XML.

As well as the raw sizing information Disk Triage provides robust analysis graphs, lists and reports showing breakdowns by file size, attribute, dates (Create/Modify/Access), time, registered file types, file extension, file owner, etc. No other utility provides this amount of detailed information about the files that make up your disk space.
