I'm a long-time Windows user in the middle of a multi-year personal migration to Linux-based development. On Windows when I installed an application it got put in the Program Files folder and I'd have the app store the files that I create while using the app in a separate data folder hierarchy that I could back up regularly.
What are the corresponding folders/directories in Linux (OK, I'm really running on a Mac)?
/Applicationsdirectory. For learning about general Linux file system organization, take a look at the FHS. – jw013 Aug 28 '12 at 20:37
