Editors' Review

ShowSize Disk Space Analyzer scans deeply and displays customizable views and reports. It's powerful enough for data professionals, network admins, and advanced users with extensive disk arrays.


Not a toy: ShowSize documents its superiority to "toy programs," pointing out that deep, thorough scanning takes time and that lightweight tools can freeze your PC mid-scan with no way out (except maybe a hard restart).

Charts and bars: We could configure many data views, including several types and levels of bar graphs, and customize columns, headings, and sort order.

Explorer mode: Right-clicking any displayed item accesses a menu full of commands, including the ability to view or open files or folders in Explorer or manage them directly in Explorer mode.


Subscription: An annual subscription instead of a one-time purchase price means you must buy ShowSize again, year after year.

Similar freeware: Some free disk space utilities come close to ShowSize in capabilities, and some (like TreeSize Free) are easier to use and read.

Bottom Line

ShowSize Disk Space Analyzer may be the most powerful tool of its type we've encountered. For pros, it's hardly overpriced, but most users should start with freeware and move up as their needs and skills evolve.

Editors' note: This is a review of the trial version of ShowSize Disk Space Analyzer 5.6.
