This is a small UDF I put together just for fun that will embed and extract complete directory's in and from your script. It only has two functions, _EmbeddedDirectory_Create() and _EmbeddedDirectory_Extract(). The udf uses Wards machine code functions so they have pretty good speed. The example I set up packs all files located in Autoit Include directory. Both compression and decompression of the directory was less than 500ms on my pc which I was happy with. Let me if you have any problems or questions. Thanks Example: #include "EmbedDir.au3" ;Check location of autoit includes Global $sIncludeDir = 'C:\Program Files\AutoIt3\Include\' If Not FileExists($sIncludeDir) Then $sIncludeDir = 'C:\Program Files (x86)\AutoIt3\Include\' If Not FileExists($sIncludeDir) Then Exit (MsgBox(0, 'Directory Not Found', 'Unable to locate Includes Directory')) ;Create embedded directory function Global $sCompressed_Includes = _EmbeddedDirectory_Create($sIncludeDir, '_Extract_Includes') Global $iTime = (@extended / 1000) & ' ms' ;create example file and write extract function to it Global $hExtractExample = FileOpen(@ScriptDir & 'Extract_Example.au3', 2) FileWrite($hExtractExample, '#include "EmbedDir.au3"' & @LF & @LF & _ '$sExt = _Extract_Includes()' & @LF & _ '_EmbeddedDirectory_Extract($sExt, @ScriptDir & "AutoIt_Extracted")' & @LF & _ 'ConsoleWrite("Extract Time = " & @extended/1000 & "ms" & @LF)' & @LF & @LF & _ $sCompressed_Includes) FileClose($hExtractExample) ;Show stats of the directory we just embeded $aSize = DirGetSize($sIncludeDir,1) If IsArray($aSize) Then Msgbox(0,"Directory Details", _ "Size = " & Int($aSize[0]/1024) & 'KB' & @LF & _ "Files = " & $aSize[1] & @LF & _ "Dirs = " & $aSize[2] & @LF & _ "Compression time = " & $iTime & @LF & @LF & _ "Open Extract_Example.au3 to extract") EndIf UDF: EmbedDir.zip
