Open 7zip.sfx 2. Use the ReadAll method of the File System Object to read the contents of this file into one long string. 3. Use the Write method to write the string into your output file. 4. Do the same with the remaining files. 5. Close the output file. If you don't have it already, download script56.chm to find out the basic objects and methods for VB Scripting. I'm not sure if it's such a good idea to translate your batch files into VB Script. VB Scripting is much more powerful than batch files but it also requires 6-10 times more code. It is not unusual for a single batch file line to translate into 20 or 30 VB Script lines - and execution will be slower too!

Thanks for your input and advice. After sitting down and thinking about it further as well as more searching on the net i came up with the following work around :D Act.run "%comspec% /c copy /b 7zip.sfx + comment-7zip.txt + " & sArchiveName & ".7z " & sArchiveName & "." & bTime & ".exe", 0, True

While this step is ok for text files, it will fail for binary files. cf: http://blogs.msdn.com/ericlippert/archive/2005/04/20/binary-files-and-the-file-system-object-do-not-mix.aspx > 3.
