Designed for speed
ShowSize directly scans a given folder. You can switch off the left pane for slow network drives. Moreover, it uses its own cache when you drill down the folders in the same report.
The virtual listing technology in ShowSize can list millions of items making it possible to produce the Only Files report described above. Ordinary software would choke on such a list.

ShowSize is a powerful disk space analysis utility. Please read more about it on the Home page.
Some examples of using ShowSize:
A disk F: is filling up fast. I want to quickly find the big-size folders and see if I can delete some.
I can do that with "Folder Sizes list." To see how this list works, please follow the link under Folder Sizes list above. Also see a demo on the Demos page.
I have a big folder "F:\Photos and Travel docs" containing lots of JPG photographs in many subfolders and also some documents and zip files. I quickly want to see how much space the JPG files are taking so that I can put them on a CD.
I can do that with "File Types list." To see how this list works, please follow the link under File Types list above.
I have a mixture of big and small files on a usb hard disk in many subfolders and just want to delete some large files to make space.
I can do that with "Only Files list." To see how this list works, please follow the link under Only Files list above.

Why choose ShowSize over other such software?
Beware of disk utilities that get locked into a long operation like a scan and don't give you any way to cancel out of it.

Print file lists easily
If you want to print a basic list of files and folders, you can use Folders and Files list. Otherwise, all the lists in ShowSize can be printed.
You can print through command line too. This helps with making batch files for printing.
"I searched on Google. Yours was the third one I downloaded and tried but
the only one which really does what I was looking for. It's amazing that
something so simple in concept was so hard to find. I am very pleased
with Showsize."
"Your program is saving me a ton of time and the ownership information is invaluable to me! The latest version with that optional "owner" and "modified" columns are exactly what we needed! I'm also very glad that it works with Windows 7 64-bit."
"It's also very cool to work with a program that when you hit cancel on a long running operation with over 300,000 entries, that it actually works! The program is great!"
