For internal developper usage only.
Note: For egal compare, the version release of Ultracopier 0.3 is compared to other. On the site the debug version is distribued to have debug repport. The debug is more slower, more bigger and use lot of more memory.

I wanted to compare my product to be full all copiers existing file. Take it for a more personal view, I therefore compared ultracopier, supercopier, teracopy and copyhandler.
I update it frequently to have good point of view of ultracopier 0.3.

1. Crash of the explorer, when ultracopier close, restart, and try copy
2. Is in pre-alpha version, I think it have lot of stuff to improve
3. destination not removed when canceled
4. Due by Qt 4.8, but thanks to that's it have multi-platform support
5. Constant base size, no memory leak, the size seam fix after close windows copy
