Supported Directory Variables

The policy for modifying the user data directory and other paths for Chrome to use has support for several variables, so you don't need to set a hard-coded path for all users. For example, if you want to store your profile data under the user local application data on Windows, set the UserDataDir policy to : "${local_app_data}\Chrome\Profile" Which on most Windows 7 / Vista installations would resolve to : C:\Users\CurrentUser\AppData\Chrome\Profile.

Chrome profiles are not backwards compatible, so storing the user profile on a network drive and using it with different versions of Chrome can cause crashes and data loss. Please see http://www.chromium.org/administrators/common-problems-and-solutions for more details.

Some hints about setting paths in policies

List of supported path variables

All platforms

${user_name} - The user that is running Chrome (respects suids).
(example resolution: "johndoe")

${machine_name} - The machine name possibly with domain
(example resolution : "johnny.cg1.cooldomain.org" or simply “johnnyspc”)

Windows only

${documents} - The "Documents" folder for the current user.
(example resolution : "C:\Users\Administrator\Documents")

${local_app_data} - The Application Data folder for the current user.
(example resolution : "C:\Users\Administrator\AppData\Local")

${roaming_app_data} - The Roamed Application Data folder for the current user.
(example resolution : "C:\Users\Administrator\AppData\Roaming")

${profile} - The home folder for the current user.
(example resolution : "C:\Users\Administrator")

${global_app_data} - The system-wide Application Data folder.
(example resolution : "C:\AppData")

${program_files} - The "Program Files" folder for the current process. Depends on whether it is 32 or 64 bit process.
(example resolution : "C:\Program Files (x86)")

${windows} - The Windows folder (example resolution : "C:\WINNT" or "C:\Windows")

${client_name) - The name of the client pc connected to an RDP or Citrix session. Take into account that this variable is empty if used from a local session. Therefore if used in paths you might want to prefix it with something which is guaranteed to be non-empty.
(example : C:\chrome_profiles\session_${client_name} - produces c:\chrome_profiles\session_ for local sessions and c:\chrome_profiles\session_somepcname for remote sessions.)

${session_name} - The name of the active session. Useful for distinguishing multiple simultaneously connected remote sessions to a single user profile.
(example resolution: WinSta0 for local desktop sessions)

MacOS only

${users} - The folder where users profiles are stored
(example resolution : "/Users")

${documents} - The "Documents" folder of the current user.
(example resolution : "/Users/johndoe/Documents")
