I am relatively new to Linux, I am using Xubuntu 10.04.
A lot of the software I download from the net, e.g. Aptana/Eclipse are just ZIP files that I open and run.
I wish them to be in a specific folder where I can reach them from everywhere when I run "Eclipse".
I want them to be available to all users.
I want to be able to start them from the drop-down menu on the desktop.
How can I do that?
