This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • So how do I find the answers? – eddyq Feb 11 at 14:39

The executables are located in the /usr/bin folder. I guess pressing Alt+F2 and typing


will do. It might also fall under the Applications menu > Internet.

To uninstall already installed software, you can:

  1. Go to Software-center. Find the software and remove.
  2. Open a terminal, and type

    sudo apt-get remove <software-name>

If you do not know the complete name, just type a few characters of the application, and press tab twice. That will auto complete, or show a list of matching applications.

    You don't need the whole path when using Alt+F2 (or the terminal or desktop/panel shortcuts). Just typing skype will suffice. – sepp2k Oct 23 '10 at 11:31
  • Oops, overlooked that! Thanks for the heads-up. But there was a time that I had to give the entire path. Dont remember the applicaton now. – theTuxRacer Oct 23 '10 at 11:45
  • You have to give the full path if you don't install it "properly"... – 8128 Oct 23 '10 at 17:43
  • you can find local software in /usr/local also. – Parixit Aug 23 '13 at 7:04
  • Where is installed application's folder?! For example tomcat7 folder. – Dr.jacky Jun 24 '15 at 5:43

You can discover where a package puts its 'stuff' by running:

dpkg -L 'packagename'

There's still a set of 'standard' locations that programs are put into. For example, binaries (in windows parlance 'executables') are put in /usr/bin, and documentation is put in /usr/share/doc in a Ubuntu system.

This is a pretty simplistic answer. For more details about how linux/unix directories are typically structured, see this:

There are some very good answers to a similar question to yours over at

What is the Linux equivalent to Windows' Program Files?

But the general idea is that the /bin and /usr/bin are where the start up application files (executables or scripts) are stored. The direct equivalent of "Program Files" though is probably /usr/share this is the directory that contains the various support files for most applications

For a good overview of the Ubuntu file structure check out the link below.


  • Many of the files in /bin and /usr/bin are scripts, but more are actual binary executables. – Eliah Kagan Jun 16 '12 at 4:56

There is no "Program Files" Directory in Linux. The Application's Parts are distributed according to what they are. There are a lot of explanations of the Directory Structure out there, you can use this one for a start.
