FileCopy unable to copy new files when source files number excess 10k

Reported by: anonymous Owned by:
Milestone: Component: AutoIt
Version: Severity:
Keywords: Cc:


When using filecopy with wildcard, like
FileCopy ("X:\*.bin", "C:\Program Files\test")
If source folder contains more than 10000 files, it will run but wouldn't copy any files to the target folder.

This script runs fine for me:

For $x = 1 To 10005
	FileWriteLine($x & ".txt",$x)
$FileCnt = DirGetSize("C:\temp\test2",1)
ConsoleWrite(" Files in C:\temp\test2:" & $FileCnt[1] & @CRLF)

It creates 10005 files in a directory and then copies them to a new directory.
Are you sure that none of the files is in use since FileCopy will stop processing when that happens.

Here is my test code

For $x = 1 To 13005
	;FileWriteLine($x & ".txt",$x)
FileWriteLine($x & ".txt",$x)
$FileCnt = DirGetSize($SourceDir,1)
ConsoleWrite(" Files in " & $SourceDir & ": " & $FileCnt[1] & @CRLF)
$FileCnt = DirGetSize($TargetDir,1)
ConsoleWrite(" Files in " & $TargetDir & ": " & $FileCnt[1] & @CRLF)

Ooops! The new files aren't copied!

>Running:(\Program Files\AutoIt3\autoit3.exe "I:\temp\test.au3"    
 Files in i:\temp\test1: 13006
 Files in i:\temp\test2: 13005

Well, the error is really quite obvious. You created 13,005 files, copied them all, then created 1 more file and told FileCopy() to copy all the files again but did not specify the overwrite flag. FileCopy() stops on the very first file because it's not allowed to overwrite. This is obviously not quite expected (or documented) behavior but I'm certain that it is no bug, either.

But I think we expect FileCopy() will "copy all new files and skip existing files".

Replying to Nitrogen:

But I think we expect FileCopy() will "copy all new files and skip existing files".

Filecopy is doing what Windows does and stop when Windows stop.
You cannot expect such behavior
I will close again
