Why my app has crashed when DirMove a large folder

Recommended Posts

Hi all.

I have a problem when I using DirMove a large folder, my app has crashed. It's show message box ".....has stopped working. A problem caused the program to stop working correctly..." and a button "Close program".

Code: DirMove(@TempDir & '\xxxFolder', 'H:\', 1)


+ H: is a USB Flash

+ The xxxFolder is a folder larger than 1GB.

Someone help me this problem.

Thanks for all.

mmm.. try this..

1. check file permission

2. try to use #RequireAdmin

3. and..... my suspect is that.... usually this folder have trouble because other programs like antivirus etc... stay connect and the the files results open, try to copy it in your desktop and than try to use dirmove from this position.

Couple of days ago I had to copy several hundred GB to a new Server and used the following, without a problem.

_FileCopy($sSource, $sTarget, 784)

; Function Name:    _FileCopy()

Func _FileCopy($pFrom, $pTo, $fFlags = 0)
    If Not FileExists($pTo) Then DirCreate($pTo)
