Weird and probably stupid problem with DirCopy

[Kingpix]

Hello everyone!

I'm writing an installer for my application that does a backup at a certain point. I'm writing AutoIT code since 3 years, and I really can't figure out why this line doesn't work.

DirCopy(@ScriptDir, @ScriptDir & "\MWBackup", 1)

I feel REALLY stupid, that's so simple! :S

For some reason it creates the Directory but it doesn't copy files in it. Can you help me please? It works as intended with ANY other source folder.

I guess the target directory is created first and then the function tries to copy that into itself...

#include <File.au3>
Local $s_TempDir = _TempFile(@TempDir, "~", "", 7)
DirCopy(@ScriptDir, $s_TempDir & "\", 1)
DirRemove($s_TempDir & "\MWBackup\", 1) ; to avoid recursion during backup (taking a backup of the old backup)
DirCopy($s_TempDir & "\", @ScriptDir & "\MWBackup\", 1)
DirRemove($s_TempDir, 1)

Thanks for the input, but I realized there is another problem.

The @ScriptDir macro returns "E:", which is the root of the E HDD. And that's correct, but after doing some research I found out that DirCopy doesn't work with HDD roots.

Even though, it seems weird to copy something inside itself.

Edit: If this last does not work you can do a recursive copy, there may be some examples on the forum (e.g: _RecFileListToArray combined with FileCopy) .

Br, FireFox.
