Application Support folders

Application Support folders are special locations where programs can store important files. OmniGraffle checks these folders for Diagram styles, AppleScripts, stencils, and templates. Each of these file types has its own appropriately named folder inside the OmniGraffle Application Support folders.

Files in ~/Library/Application Support/OmniGraffle/ (where ~ is your home folder) are only available when OmniGraffle is used from your user account. You don't need any special privileges to add or remove files there.

Files in /Library/Application Support/OmniGraffle/ are available to any account on your computer. You need administrative privileges on the computer to add or remove files there.

Files in /Network/Library/Application Support/OmniGraffle/ can be seen by any copy of OmniGraffle being used by anyone on the entire network. You need administrative privileges on the network to add or remove files there.
