MouseSoft Directory Size

MouseSoft Directory Size is a tool that shows the size of your files and folders, highlighting the largest ones. It can help you identify possible items to delete in order to free up space, as well as to reorganize your disk space.

Simple setup and GUI

The installation procedure is fast and shouldn't give you any trouble. When it comes to the interface, it's obvious that MouseSoft Directory Size is outdated, due to its classical-looking window that takes us back to older Windows models.

View the largest items and save info

You can use the built-in tree view to explore disk drives and view the size of files, folders and subfolders, along with the total size in the status bar. The disk drive can be changed from a drop-down menu.
Items can be sorted by filename or size. It's possible to copy information to the Clipboard, print it, save it to file by specifying the output directory, filename and format (TXT or HTML), as well as to send it to the web browser, email client (as attachment), Notepad, or Microsoft Excel. There are no other notable options available here.

Evaluation and conclusion

Although it hasn't been updated for a long time, it worked smoothly on newer Windows editions in our testing, without triggering the operating system to hang, crash or prompt errors. As we expected, it didn't put a strain on the overall performance of the machine, thanks to the fact that it needed a low amount of CPU and memory to work properly.
On the other hand, it comes equipped with a light set of options that don't make MouseSoft Directory Size appealing for experienced users looking for more versatility. Nevertheless, you can test it for yourself, since it's free for non-commercial use.
