Slow file "Move" on Windows with NTFS #1057

I think there is a problem related to file move function. If I move some duplicated files from the path D:\folder1 to the path D:\folder2, the movement should happen quickly, as it does when using explorer.exe, because the files are not actually moved but only their new location is written to the file system. However, with czkawka, the move function rewrites the files, making the operation very slow and putting the files at risk because they undergo an unnecessary transfer operation.

Exactly the same happens on Linux (ext4 filesystem). The files are copied to the new location while a move operation would be a lot more efficient.
