Gramps 4.0 Wiki Manual - User Directory
The location of your GRAMPS user directory depends on the operating system you are using and how you have set up your computer. In the table below <~username> should be replaced by the name you use to log in to your computer.
The default location for an installation of GRAMPS in a POSIX-style environment is:
/home/<~username>/.gramps
This is true for BSD, Linux, Solaris, Unix and OS-X when using Mac OS X Build from source.
On Macs, filenames starting with "." do not show up in Finder. To make access to the Gramps user directory easy, open a terminal window with Finder-Applications-Utilities-Terminal and type there
ln -s .gramps gramps_user_directory
which will allow Finder to show the contents. Or simply click on Go -> 'Go to Folder...' in the Finder, and type
~/.gramps
in the Go to Folder dialog box.
The default location for an installation on a Windows system is
C:\Documents and Settings\<~username>\Application Data\gramps
On Windows7, it is
C:\Users\<~username>\AppData\Roaming\gramps\gramps34
The default location for the Mac OS X:Application package is
/Users/<username>/Library/Application Support/gramps
