Speed/Security of ultracopier, SuperCopier, TeraCopy and copyhandler

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.
