Run chrome with this command line switch  
  
chrome.exe --user-data-dir="..\\valid path to a directory\\" -first-run  
  
One easier way to run different chrome profile is

1.  Create a chrome application shortcut
2.  Right click, go to properties in the application path add this  
     --user-data-dir="..\\valid path to a directory\\" -first-run  
    after chrome.exe

**Introduction**  
The user data directory contains profile data such as history, bookmarks, and cookies, as well as other per-installation local state.

Each profile is a subdirectory (often Default) within the user data directory.

**Current Location**  
To determine the user data directory for a running Chrome instance:

**Navigate to chrome://version**  
Look for the Profile Path field. This gives the path to the profile directory.  
The user data directory is the parent of the profile directory.  
Example (Windows):

\[Profile Path\] C:\\Users\\GbHi8bXhDyMP2m1NDUSiYmznAJdJzX36DDUser Data\\Default  
\[User Data Dir\] C:\\Users\\GbHi8bXhDyMP2m1NDUSiYmznAJdJzX36DDUser Data  
Default Location  
The default location of the user data directory is computed by chrome::GetDefaultUserDataDirectory.

Generally it varies by

**OS platform,**  
branding (Chrome vs. Chromium, based on is\_chrome\_branded in GN args), and  
release channel (stable / beta / dev / canary).  
**Windows**  
The default location is in the local app data folder:

\[Chrome\] %LOCALAPPDATA%\\Google\\Chrome\\User Data  
\[Chrome Canary\] %LOCALAPPDATA%\\Google\\Chrome SxS\\User Data  
\[Chromium\] %LOCALAPPDATA%\\Chromium\\User Data  
(The canary channel suffix is determined using InstallConstants::install\_suffix.)

**Mac OS X**  
The default location is in the Application Support folder:

\[Chrome\] ~/Library/Application Support/Google/Chrome  
\[Chrome Canary\] ~/Library/Application Support/Google/Chrome Canary  
\[Chromium\] ~/Library/Application Support/Chromium  
(The canary channel suffix is determined using the CrProductDirName key in the browser app's Info.plist.)

**Linux**  
The default location is in ~/.config:

\[Chrome Stable\] ~/.config/google-chrome  
\[Chrome Beta\] ~/.config/google-chrome-beta  
\[Chrome Dev\] ~/.config/google-chrome-unstable  
\[Chromium\] ~/.config/chromium  
(The beta and dev channel suffixes are determined from $CHROME\_VERSION\_EXTRA, which is passed by the launch wrapper script.)

The ~/.config portion of the default location can be overridden by $CHROME\_CONFIG\_HOME (since M61) or by $XDG\_CONFIG\_HOME.

Note that $XDG\_CONFIG\_HOME affects all applications conforming to the XDG Base Directory Spec, while $CHROME\_CONFIG\_HOME is specific to Chrome and Chromium.

**Chrome OS**  
The default location is: /home/chronos

**Android**  
The default location comes from Context.getDir and is specific to the app.

Example: /data/user/0/com.android.chrome/app\_chrome

**iOS**  
The default location is inside the application support directory in the app sandbox.

\[Chrome\] Library/Application Support/Google/Chrome  
\[Chromium\] Library/Application Support/Chromium  
Overriding the User Data Directory  
Command Line  
On all platforms, the user data directory can be overridden by passing the --user-data-dir command-line flag to the Chrome binary.

**Example:**

\[Windows\] chrome.exe --user-data-dir=c:\\foo  
\[Linux\] google-chrome --user-data-dir=/path/to/foo  
**Environment (Linux)**  
On Linux, the user data directory can also be overridden with the $CHROME\_USER\_DATA\_DIR environment variable.

The --user-data-dir flag takes precedence if both are present.

**Chrome Remote Desktop sessions (Linux)**  
A single Chrome instance cannot show windows on multiple X displays, and two running Chrome instances cannot share the same user data directory. Therefore, it's desirable for Chrome to have a separate user data directory when running inside a Chrome Remote Desktop (CRD) virtual session on a Linux host.

By default, CRD achieves this by setting $CHROME\_USER\_DATA\_DIR in the session. Unfortunately this means that inside the session we don't get separate defaults for different channels (Stable, Beta, Dev) or for Chrome vs. Chromium. This can lead to profile version errors (“Your profile can not be used because it is from a newer version of Google Chrome”).

Since M61, this can be solved by setting $CHROME\_CONFIG\_HOME instead of $CHROME\_USER\_DATA\_DIR. Specifically, put the following in ~/.chrome-remote-desktop-session:

export CHROME\_CONFIG\_HOME="$HOME/.config/chrome-remote-desktop/chrome-config"  
unset CHROME\_USER\_DATA\_DIR  
. /etc/chrome-remote-desktop-session  
Then restart the host by running: /etc/init.d/chrome-remote-desktop restart

**Writing an AppleScript wrapper (Mac OS X)**  
On Mac OS X, you can create an application that runs Chrome with a custom --user-data-dir:

Open Applications > Utilities > Script Editor.

Enter:

set chrome to "\\"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome\\""  
set userdatadir to "\\"$HOME/Library/Application Support/Google/Chrome Alt\\""  
do shell script chrome & " --user-data-dir=" & userdatadir & " > /dev/null 2>&1 &"  
Modify as needed for your installation path, Chrome versus Chromium, and desired user data directory.

Save the script in your Applications directory with the file format “Application”.

Close the Script Editor, find your newly created application, and run it. This opens a Chrome instance pointing to your new profile.

If you want, you can give this application the same icon as Chrome:

Select the Google Chrome application and choose File > Get Info.  
Select the icon at the top left of the info dialog. You will see a blue highlight around the icon.  
Press ⌘C to copy the icon.  
Open the info dialog for the new application and select the icon in the top left.  
Press ⌘V to paste the copied icon.

**User Cache Directory**  
On Windows and ChromeOS, the user cache dir is the same as the profile dir. (The profile dir is inside the user data dir.)

On Mac OS X and iOS, the user cache dir is derived from the profile dir as follows:

If Library/Application Support is an ancestor of the profile dir, the user cache dir is Library/Caches plus the relative path from Application Support to the profile dir.  
Otherwise, the user cache dir is the same as the profile dir.

**Example (Mac OS X):**

\[user data dir\] ~/Library/Application Support/Google/Chrome  
\[profile dir\] ~/Library/Application Support/Google/Chrome/Default  
\[user cache dir\] ~/Library/Caches/Google/Chrome/Default  
On Linux, the user cache dir is derived from the profile dir as follows:

Determine the system config dir. This is ~/.config, unless overridden by $XDG\_CONFIG\_HOME. (This step ignores $CHROME\_CONFIG\_HOME.)  
Determine the system cache dir. This is ~/.cache, unless overridden by $XDG\_CACHE\_HOME.  
If the system config dir is an ancestor of the profile dir, the user cache dir is the system cache dir plus the relative path from the system config dir to the profile dir.  
Otherwise, the user cache dir is the same as the profile dir.

**Example (Linux):**

\[user data dir\] ~/.config/google-chrome  
\[profile dir\] ~/.config/google-chrome/Default  
\[user cache dir\] ~/.cache/google-chrome/Default  
On Android, the user cache directory comes from Context.getCacheDir.
