    Best drive size information and directory add-on. My favorite for many years.They achieve what might seem impossible with every update: Make it even better. FAST? No, faster than FAST! SUPER FASTIf size of elements on a storage is something you have to watch; this tool is IT !SUPERB add-on; right-click to view folder sizes in detailed drive view. Pros: Speed, and add-on to detailed view of repertoires that shows sizes for all directories.Unintrusive, never slows down anything. Cons: I am jalous of such outstanding talents of the creators.They SEE the big picture of creating applications:GoalSpeedInterfaceLooksIntegration of it all and add that special touch that shows that they have incredible talents.Jalous... of such talent in application design.

    An organizational tool that everybody should use.. I have owned T.S.P. since you released it. With every upgrade, the Program only gets better. I believe in keeping not only my files in perfect order but, my operating system as well. T.S.P. gives me LOTS of tools for just that purpose. It even scanned and retains all the information on my slave drives, all three of which are 2 TB in size. One thing I always had problems with was file duplication. I have over 65,000 Jpgs and GIF89 files I use to create "Windows" themes along with perhaps 10,000 sound files for the same use. When copying files to slave drives for backup, T.S.P. helped with it's duplicate file finder. I cannot tell you how many duplicates it turned out were present on the first backup that T.S.P. found and helped me eliminate. That is only one of the many helpful tools available. Yes, the people who created this Program did an excellent job. Pros: Fast to load. Fast to scan. Light memory load on the operating system. Integration into the "Windows" subsystem went perfectly. Nice "right" click tree options. Cons: Some of the tools available are difficult to find for a beginner. Suggest you create a "toolbox" where ALL tool or, helper apps can be seen as icons with text.

    Professional is necessary for busy computer owner. The difference between Personal and Professional is great. Professional is working with NAS-drives as well normal server. And one of the best things is: Searching is faster than with Windows 7. And the best is the easy cleanup of temporarily files (search, Ctrl-A and delete).
