There is a problem related to the technique used in extracting the children of selected directory.  If the directory structure under the selected directory is very large, this makes the list of arguments too long thus making it impossible to start the sub process.

Two things can be done to solve this problem.  If the top most directory inside the archive is selected and there are no siblings for it, the command used should be the same as the one for extracting all files.

If the above cannot be done, then the extraction must be done in steps by extracting a subset of the selected files files and then extracting the rest in further steps.  This would reduce the number of arguments passed in each execution.
