What Our Customers Say About TreeSize

I wanted to thank you for saving my week. I found out our cloud backup hadn't synced for two weeks! I panicked about how to get 75 GB of data, randomly distributed across our network, offsite. But first I had to figure out what files had changed in the last two weeks so, as always when **searching** across a huge area for a file, I used TreeSize File Search. That was half the battle. Only then did I discover that it's incredibly easy (and fast) to select all and copy the files with the full path and permissions to an external drive! Wow, what a huge relief! So thank you for a truly great piece of software.

I have been using TreeSize for many many years and totally love it! One of the first softwares I install on every new system I come to.

Cheers and thanks for a super great software!

Thank you for the ongoing support for TreeSize.
I'm in independent consultant and on many occasions I was able to wow my customer just by using your tool. The duplicate file finder and the size changed over time are killing features for me.
Just yesterday I was able to demonstrate that a certain action of just manually updating a set of excel files would be a near impossible task since I was able to show them in less than 10 min that they had over 20.000 excels hidden in their network share.

The simplicity and speed is just awesome!

I have the highest regard for TreeSize. It is so good that, if I accidentally use Windows File Explorer, which can be ponderously slow, I can switch to the home screen, startup TreeSize, enter the parameters, and have my answer before File Explorer has even finished its search! I don’t know what I would do without TreeSize: As an economics researcher, I have about 10 000 articles all stored in one folder – plus data, graphs, publications, etc. in other folders – and TreeSize goes through these almost instantly. And I love the new interface which allows using RegEx type searches without the pain of raw RegEx coding.

Very glad I bought the software yesterday!
I've seen my software company's support staff use Treesize.

I'm personally always pretty hesitant about purchasing software. But after trying out the trial... MAN!
It's night and day difference when compared to Windirstat.

The speed difference alone is incredible!

I've just tried a scan on a large bucket and it reported the results far quicker than I can get the results directly from the aws console!! Great work!! Amazing.

I remain super impressed with your work, thanks loads.

TreeSize Professional from JAM Software is the most powerful program I’ve seen for analyzing how disk space is being used. Just load the program and specify the areas you want to scan. These can be one or more local partitions or paths, or partitions or paths on networked computers. Hit the Scan button and wait a while. But you don’t have to wait long! TreeSize is lightning quick. My local hard drive, which is partitioned as a main C: partition and a supplementary D: partition, has almost 450,000 files using 665 GB. The scan completed in 37 seconds!

I LOVE the product and we use it daily for not only reporting but for administering our CIFS environment. *Honestly I'm probably doing more with the product than you intended but it has been a life-saver for my department.

TreeSize is a wonderful utility and gives a view of my computer storage in a way that no operating system does. It has helped me get to the root of many issues, equipped with the tools to fix them.

With file storage evolving across external drives and internet storage, TreeSize makes it easy to view everything, and manage it properly. Duplicate file scanning across multiple drives saves a great deal of time and wasted space.

I LOVE this software! I will totally be recommending it to my clients.

Yesterday I discovered TreeSize and downloaded a trial version. Kudos to the developers! You have done an incredible job with this program. Your team is remarkable. Incredibly perfect software! The straightforward clean design and functionality is absolutely amazing. I am an IT Director and will recommend this product to anyone that I think might find it very useful. It is always refreshing to experience clean, precise and intelligent software that truly makes life easier by saving valuable time.

This works like a charm. I was able to replace two software applications (Easy Duplicate Finder and SpaceWatch) with your current TreeSize Pro version.

Thank you, JAM Software, for dreaming up this application. It helps me manage local and NAS Storage more efficiently.

TreeSize is a great tool. It comes in three versions which you can compare on their website - Freeware, and two paid versions. [...]
TreeSize turned out to be just the solution I needed. If you keep running out of disk space and you have exhausted all the common disk clean up routines, give TreeSize a try.

This program has been TREMENDOUSLY useful to me. In particular, apart from figuring out what's going on in my own machine, it is GREAT for examining my LINUX file systems that I have mounted over Samba.

4 stars out of 5

Editor's Review: Excellent

Wondering where all your disk space went? Care to see how you're using your disk space and which folders take up the most space? You can easily do that with the powerful and flexible application TreeSize Professional. Any user who cares about efficiently using disk space is well advised to get this hard disk space manager.

After hours of struggle I downloaded your product and found out what was eating up my disk space in less than a minute and took steps to resolve the problem. I thought I had a virus and was just about to wipe my computer and start again. It turned out to be a piece of legitimate software that was filling up my disk with log files. Thank you - thoroughly recommended.
