User Reviews

  • Hi, have you got any email to report you translation typos of your main site page, because this site accepts only bugs caused at the very program with configuration?

  • I downloaded to compare .iso files. On first use, it didn't do what I needed, ergo down vote. It may be great for smaller files, but the 2GB limit sucks, and it's therefore unusable for my purposes.

  • I wanted to compare some large files (~4 GB) but received a message stating that the limit was 2 GB.

  • This program appeared to be just what I needed and it might be if I could install it. I've tried 4 or 5 times now and each time when it's mid-way extracting files, that's it. It just stops. I can't click on the window and move it, minimize it, close it, cancel it. The progress bar still does its cutesy thing but I have to go to the task manager to stop it. And now I've got useless junk stuck somewhere in my computer and I can't get rid of it. I can't even find how to report this issue as a bug. What a pain!!! From what I can see most people have been able to use it so I don't know what the problem is trying to install it on my system. I've never had a problem like this before. I have a 64-bit AMD processor and I'm running Windoze 7.

  • nice program to compare folders, I recommend it!
