Finding all cycles in a directed graph
...point of multiple practical algorithms which apply various enhancements in order to improve performance and avoid cycle duplication. I was surprised to find out some time ago that these algorithms are not readily available in textbooks and on the web. So I did some research and implemented 4 such al...

In order to remove the System bit without changing other bits, use
Folder.Attributes &= ~FileAttributes.System;
