junctions supported!

about TreeSize Apr 2016

This great application supports junctions and do not add junction's target sizes in reports!

But it do not understand hard links, and it's sizes in report are duplicated (

[Edited by Nashev, April 22]

Non-free version supports hardlink resolving! And deduplicatioin by creating hardlinks for same files have!


The question

Comment by johnbarness
about TreeSize Feb 2016

Thank you for review!
I have a question is it required to be installed or it's portable? This makes sense for me because I've got many computers to check and do not want to install the copy on everyone. Many people writes it crashes all the time but I'd like to check it out. I think the software like this will not be needed in the nearest future because people start relying on cloud storage like [Ideals]( ) that are more efficient and can be reached from everywhere leaving your own hdd free.


Treesize is a piece of junk

about TreeSize Oct 2014

Crashes everytime I use it (and I have plenty of RAM). Version is older version, but I got tired of developer constantly hitting up for more $$$ for additional updates that don't fix anything.


Best free disk space manager ever!

Positive Comment by Cayren
about TreeSize and SpaceObServer Feb 2013

TreeSize Free is a great program for managing disk space. It's fast, it's free, and it presents all information in a very clear overview.

It works on Win 7 and Win 8.

TreeSize is updated fairly regularly, this way you're always up to date.

I'm a proud owner of TreeSize Professional, but I always carry the free version on an USB stick to have it close by when yet another friends asks me to help them because their computer has inexplicably slowed down or complains about low disk space. :)

The full versions are even more awesome and offer really great features such as deduplication and NTFS support.

Added bonus: The folks at JAM are really friendly and offer a-plus support.

Great software, try it out yourself!

TreeSize Free can show only the size of local folders or local drives, not of network folders
Very good free applications to examine the foldersize of NETWORK drives are:
(1) WinDirStat:
(2) JDiskReport:
(3) FreeCommander:
A very good commercial application to examine the foldersize of NETWORK drives is:

Beside many other useful functions FreeCommander shows (also sorted) how much space the files and directories consume on your disk drives, similar to JDiskReport or TreeSizeFree, but as opposed to "Treesize Free" also on network disk drives.
