* Example:
* FileUtil::copyDir('b','d/e'); Test copying the folder Create a d/e folder and copy the contents of the b folder into it
* FileUtil::copyFile('b/1/2/3.exe','b/b/3.exe'); Test copying files Create a b/b folder and put it in the b/1/2 folder Copy the 3.exe file into it
* FileUtil::createDir('a/1/2/3'); Test creating a folder Create a folder a/1/2/3
* FileUtil::unlinkFile('b/d/3.exe'); Test deletion of files Deletion of b/d/3.exe file
