Help with adding xtool to my installer script

[KaktoR]

Your method chain does not make any sense.

You have to process the complete method chain in one go. What you did was first using xtool for itself, so xtool is out of the chain, hence

so there will be a big size consumed on the hard drive so
i want my installer to delete the xtool archive after other methods extracted there files successfully

After that, you compressed the xtool archive.

{precompressor}+srep+{compressor} is a better chain for most purposes.
