Hi, I do recognize bad behaviour at this snippet: #include <AutoItConstants.au3> Global $g_sSD = @ScriptDir & "\" Global $g_sBurstPath = $g_sSD & "Burst\" DirCreate($g_sBurstPath) Local $sFileName = "Test_mit_3_Seiten.pdf" ; any PDF with more than 1 page inside @ScriptDir FileCopy($g_sSD & $sFileName, $g_sBurstPath & $sFileName, 1) ;~ Sleep(13000) Local $hTimer = TimerInit() ConsoleWrite("Start" & @CRLF) _Burst($g_sBurstPath & $sFileName) ; bursts PDF into single pages ;~ While _FileInUse($g_sBurstPath & $sFileName) ;~ WEnd ConsoleWrite("End: " & Round(TimerDiff($hTimer)) & "ms" & @CRLF) Exit Func _quotePath($sPath) ; because of possible "spaces" inside pathes $sPath = '"' & $sPath & '"' Return $sPath EndFunc Func _Burst($sFile) Local $sPDFtk = $g_sSD & "pdftk.exe" ; path to pdftk.exe (and libiconv2.dll) Local $sCurrWorkingDir = @WorkingDir FileChangeDir($g_sBurstPath) ; it has to change for reasons Local $iPID = Run(_quotePath($sPDFtk) & ' ' & _quotePath($sFile) & ' burst', "", @SW_SHOW, $STDOUT_CHILD + $STDERR_CHILD) ; @SW_SHOW just to see "PDFtk is working" Local $sOutput, $sError While 1 $sOutput &= StdoutRead($iPID) $sError &= StderrRead($iPID) If @error Then ExitLoop Sleep(10) WEnd FileChangeDir($sCurrWorkingDir) ; back to normal EndFunc Func _FileInUse($sFilename) ; by Siao Local $aRet, $hFile $aRet = DllCall("Kernel32.dll", "hwnd", "CreateFile", _ "str", $sFilename, _ ;lpFileName "dword", 0x80000000, _ ;dwDesiredAccess = GENERIC_READ "dword", 0, _ ;dwShareMode = DO NOT SHARE "dword", 0, _ ;lpSecurityAttributes = NULL "dword", 3, _ ;dwCreationDisposition = OPEN_EXISTING "dword", 128, _ ;dwFlagsAndAttributes = FILE_ATTRIBUTE_NORMAL "hwnd", 0) ;hTemplateFile = NULL $hFile = $aRet[0] If $hFile = -1 Then ;INVALID_HANDLE_VALUE = -1 $aRet = DllCall("Kernel32.dll", "int", "GetLastError") SetError($aRet[0]) Return 1 ; file in use (@error contains system error code) Else ;close file handle DllCall("Kernel32.dll", "int", "CloseHandle", "hwnd", $hFile) Return 0 ; file not in use EndIf EndFunc This bursting took about 15000ms. If I activate line 8 "Sleep(13000)" then the bursting itself never needed more than 1000ms. Round about 13000ms delay is needed until bursting is acting very fast, otherwise needing about 15000ms. Then I tested _FileInUse() instead of _Burst() w/o Sleep(13000). This runs in 3ms. It seemes to me that FileCopy() and Burst() are interacting in a way I can't see. Any ideas? Regards, Conrad P.S. You need pdftk.exe and libiconv2.dll at @ScriptDir. This you can get free here: https://www.pdflabs.com/tools/pdftk-server/ (I'm not sure whether I'm allowed to attach it here).
