Delete SFX file after extraction

Question

I created a SFX to extract some files. After the extraction, I need that the SFX file is deleted. As far as I have seen, WinRar does not offer such option. So I thought to run some DOS command -prompt (like bat).

This is my code so far (not working):

SETUP=cmd /c del /f /q "file-to-delete"

It opens the cmd, flashes and then closes...

Someone with a similar problem: http://www.msfn.org/board/topic/34506-sfx-remove-file-after-extraction/

Solution

See if this works - include the accurate path to the file and see if it deletes it. If it does then you can try relative paths.

SETUP="%comspec%" /c del "c:\program location\file-to-delete"

If that fails then include this command in a bat file located where the file is and then use the bat file to delete the SFX file, in the WinRar directive.

@echo off
del "file-to-delete"

is your SETUP= a WinRar directive? Ensure the full path to the file is included.

Yes, "SETUP=" is AN winrar diretive and it allows to run a specific program after the SFX automatic extraction, which can be "Setup.exe" or "Install.exe" or "script.bat", etc... the path is fine I just can't find the way to make it works

Your problem is that the SFX is still running, so if you try to delete it you're only going to end up with an Access Denied error.

[Rafael Vidal]

Karan, that's not the case. Winrar have specicif directives to be used BEFORE, DURING or AFTER the exctraction process. In this case, the SETUP directive is excevuted at the ende (after SFX has finished). So there is no problem to delete the file. By the way, foxidrive has the exactly solution. Thank you by the way.

PERFECT! "%comspec%" /c del "c:\program location\file-to-delete" made the trick. But how did you know?
