What is TreeSize?

TreeSize Professional tells you where precious disk space has gone to. It can be started from the context menu of a local folder or a local drive and displays the size of each folder, including its subfolders.

"TreeSize Professional" will allow you to scan NETWORK drives. Scanning is done in a thread, so you will see results while TreeSize Professional is still working.

TreeSize Professional is a powerful and flexible harddisk space manager. Find out which folders are the largest on your drives and recover megabytes of disk space.

TreeSize Professional shows you the size, allocated and wasted space, the number of files, 3D charts, the last access date, the file owner and permissions, the NTFS compression rate and much more information regarding folders or drives. It also lets you search drives, entire servers or the entire network for old, big, temporary and duplicate files.

TreeSize Professional includes Disk Space Management on smartphones and mobile devices.

I have loved, and continue to love, TreeSize Free for many, many years (more than 10 years and counting). Whenever I get a new computer it is one of the first things I install.

It is simple, fast and unbloated. So many disk usage analytic tools waste their efforts on fancy looking charts but don't help the user with their most essential goal - to quickly identify exactly what is using the most space on their storage device.

TreeSize Free, however, excels at this. It quickly analyzes your hard drive (for example, one of my drives had over 480,000 files using over 950G of space, TS Free analyzed the entire drive in under 20 seconds). It presents your entire drive as an interactive tree sorted by file size (or even file counts, if you prefer), allowing you to expand or collapse each directory so you can quickly zoom in on exactly what you need to remove in order to free up the most space in the shortest amount of time.

As an example, I launched TS Free on one of my computers. This one has a 1TB drive but less than 60G free space remaining. I knew it had lots of downloads and photos - but not that much! What was taking up so much space?? It took TS Free 17 seconds to analyze this drive. Right away the problem is revealed - over 460G is consumed by 18 files in "C:\System Volume Information". After a quick online search I found that these are system restore points, and the amount of space they occupy is configurable via the system protection utility in W7 (but that's a topic for another day). All I had to do was adjust the system protection options to reduce the restore point disk consumption. But the important point here is that I quickly got to this solution with excellent assistance from TreeSize Free.

The biggest limitation of the free version (AFAIK) is that it won't analyze network drives. That hasn't been a big issue for me, so I haven't had to opt for the Pro version.

The free version is great, but check out the full version to get the whole range of features.

TreeSize is fast (even faster in new version 6), comes with a great file search feature, supports NTFS, can find and remove duplicate files and is all in all the best application for disk space management I know. For servers I use the "big brother" SpaceObServer.

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.

Try the free version (TreeSize Free), it is awesome and does not hit up for $$$, ever. The biggest limitation in the free version is that it doesn't support network drives. If that's a limitation you can live with, then definitely try the free version.

I've used it for years for cleaning my PC. It's easy and powerful. Best tool for manual cleaning or just to see what clutters your drive.

Does exactly what WinDirStat, but much faster. The free version was enough for me.

While I always had problems with WinDir Stat crashing when scanning large directories, the free, portable version of TreeSize completed the same task without any issues and quickly too (3+ TB with 80K files in less than a minute)

Using this I managed to clean up my external harddrive from things I didn't remember having on it, very handy.

My #1 Disc Space Analyzer was, is and it seems it will always be SpaceSniffer. The main reason is because I love how it graphically shows me what takes my space, which is way more easy to "see" what takes up my space, rather than looking at numbers, percentages and pie charts.

Still though, TreeSize is perfect when you actually want the numbers, rather than just shapes, where you want to know the exact Folder Size in your storage space. So I use TreeSize for the times I wish Windows offered the option to switch Folder Size on and off, so you can tell how much size you different folders take up, while you are browsing through your stuff.
