"TreeSize Professional is a brilliant tool you need to explore your PC and organize your work perfectly."

3d2f.com editors call the program "the best among the like"

"Just downloaded and installed the latest version of TreeSize Pro and I really like the improvements. This is one utility no IT Manager or Windows Systems Admin should be without."

"I have just upgraded to 4.0. I have used it for about 30 seconds and the difference in performance is AWESOME!!!"

"A network scan that didn't finish on a faster workstation after almost 5 days with version 3.3, finished in less than two hours on a slower, older workstation with the new version 4."

Bob Schatz

"Please note that after an exhaustive search, I could find no other utility that would give me that information other than polling each directory individually and manually."

"I just wanted to say thank you for a great program. As a network administrator, I use it often. I appreciate how fast it is. I also appreciate the way it works equally well on local drives, Netware drives, and Windows server drives."

Don Michaels

"Thank you, your product is exceptionally helpful."

Patrick Parks

"An excellent product, one of the most useful pieces of software I've ever purchased, I've made extensive use of it. Keep up the good work!"

Ed Marchewicz

"I guess you don't get too many expressions of gratitude in your business. I just wanted to say thanks for such a great and useful little application (not so little nowadays!) and such great value for money."

Bob Bater

"I continue to be impressed with the quality and usefulness of TreeSize and the ongoing support. I'm amazed at the service you provide for the low price I paid."

Leon Bevans

"I've looked through the revision history and noted the improvements you've made. You are to be commended for such an excellent product. This is just an excellent product. I don't know what else I can say other than it's superb. And I haven't yet begun to look at all the new features."

"'This program rocks!'
I can't say enough good things about this software. No learning curve, no bugs, no tweaks. It's very intuitive and behaves exactly how you would expect. What's great about this software is the return on investment is immediate. I am the IT manager where I work and we have about 50 users. The backups kept growing and growing. I budgeted for a LTO-2 autoloader but our company has been a little short on cash lately. I downloaded this software and entered the users network directory on our server. As Emeril would say, 'BAM!'. Instant answers to my questions: Who's hogging all the disc space? Who's storing their family photo album and MP3 collection on the server? It so easy too. It fully supports UNC. (\serverusers) It's very fast and has no problems working over the network. The list of small utilities I have purchased in the last few years has been very short. I'm not what you would call a utility freak. TreeSize is on my shortlist. I purchased TreeSize Pro and am now a happily registered user. "

"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."

David Jameson

"I have spent many years as a systems software engineer and head of research for a local development company, I think I'm a pretty good judge of software.

I purchased TreeSize Pro last summer. I wrote at that time that I simply could not believe the program I was seeing! I don't have Excel, but I use the XML reports constantly. I've got various procedures set up to give me the info I want. I like to know where every program puts files, and I don't like surprises.

I simply could not do what I do on the computer without TreeSize, which is why it's so valuable to me. You have a fine piece of software."

Harry Parker

"In short, what JAM gains is the full benefit of XML's "keep it simple" promise. With luck, we'll continue to find vendors of all kinds of software taking the same tack."

"As I download the latest version, I wanted to take the opportunity to compliment you. I think I have been using TreeSize since version 1, or close to that. In that time, it has been one of only a very few products that continues to be an invaluable and required part of my development environment. Outstanding work."
