Project CHROMIUM / Google Chrome user data directory

user-data-dir-chromium.TXT

Project CHROMIUM / Google Chrome:
The user data directory contains data specific to a given user.
Some examples of this type of data are: history, bookmarks, and cookies. 

Note that in Windows, the profile name is included in the directory hierarchy.


Default Location

	Windows XP
Google Chrome: C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Google\Chrome\User Data\Default
Chromium: C:\Documents and Settings\%USERNAME%\Local Settings\Application Data\Chromium\User Data\Default

	Windows 8 or 7 or Vista
Google Chrome: C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default
Chromium: C:\Users\%USERNAME%\AppData\Local\Chromium\User Data\Default

	Mac OS X
Google Chrome: ~/Library/Application Support/Google/Chrome/Default
Chromium: ~/Library/Application Support/Chromium/Default

	Linux
Google Chrome: ~/.config/google-chrome/Default
Chromium: ~/.config/chromium/Default

	Chrome OS
/home/chronos/


Cache Directory

	The cache directory follows the XDG specs:
Google Chrome: $XDG_CACHE_HOME/google-chrome, which defaults to ~/.cache/google-chrome
Chromium: $XDG_CACHE_HOME/chromium, which defaults to ~/.cache/chromium
If you pass --user-data-dir=/path/to/foo, the cache will be under /path/to/foo.


Running from a Custom Location

You can also start Chromium with a custom user data directory in order to run multiple instances at the same time.

	Windows
To do this, add the --user-data-dir flag to chrome.exe, like this: chrome.exe --user-data-dir=c:\foo

	Mac OS X
Open AppleScript Script Editor (either in Applications/Utilities or Applications/AppleScript)
	Enter this:
Google Chrome:
do shell script "/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome --user-data-dir=/Users/$USER/Library/Application\\ Support/Google/ChromePersonal > /dev/null 2>&1 &"
Chromium: 
do shell script "/Applications/Chromium.app/Contents/MacOS/Chromium --user-data-dir=/Users/$USER/Library/Application\\ Support/ChromiumPersonal > /dev/null 2>&1 &"
*If you did not install Chromium in the default location, modify the script as appropriate.
*Save the script in your Applications directory with the file format Application.
*Now close the Script Editor and find your newly created application and run it. Running this application will open another Chromium instance pointing to your new profile.
*If you want this application to have the same icon as Chromium, then select the Chromium application and type command+i to open the info dialog. Select the icon at the top left of the info dialog and you will see a blue highlight around the icon. Copy the icon using command+c. Now open the info dialog for the new script application using command+i. Select the icon at the top left and paste the copied icon using command+v.

	Linux
To do this, add the --user-data-dir flag to chrome, like this: chrome --user-data-dir=/path/to/foo
