Is there a way to clean up this folder.
I have noticed that as more applications are downloaded and updates to those applications are downloaded that the previous application is left and a newer once is placed there with an incremented number behind it.

As I have a lots of applications, and updates to those applications, it is growing in size. Can I just delete all applications except the most recent version of it?

I only thought that if I did this, that it might mess things up as a config file may be looking for all the versions of that application.

Has anyone looked into this issue?
