Do apps work without the installation file?

[coolio2654]

Hey, I'm reloading my computer to clean it up. I also got a lot of good apps on my comp that I want to preserve. After downloading apps, I delete the installation files to preserve memory. After putting my apps on a USB drive, will they work on my reloaded MAC without the installation? Some apps have been payed for and registered also, will they now work? Any thoughts would be highly appreciated.

Most of the time, yes.

Adobe apps, maybe not, maybe so. "Big" apps, like Final Cut Pro, Reason and Mathematica or Maple, maybe not, maybe so. They like to put support files in non-standard places on your hard drive, so simply backing up the applications themselves may not work.

If they're shareware apps downloaded from the internet, then most likely, yes.
