Okay, yesterday I'd posted "Multiple Login For Firefox", and now it's the time for Chrome user, here you go..
1. Firstly you need to clear all of your cookies and browsing content by choosing "Clear Browsing Data" in the Option menu, or simply just click "Ctrl+Shift+Del", we do this because we need to multiply this profile.


2. Open the folder where you install Chrome, usually it's automatic installed at:

For Windows Vista & Windows 7 - C:\Users\AppData\Local\Google\Chrome
For Windows XP - C:\Documents and Settings\Local
Settings\Application Data\Google\Chrome

But before that, make sure you tick "Show All Files" in folder option.


3. After that, open "User Data" folder, and you will see "Default" folder in it. Make a copy of that folder, and paste it in the "User Data" folder itself, and rename it with the profile name you want (in picture I use "MW99").
For Windows 7 and Vista, I think there's no problem, but in XP I think you should paste it on another folder, rename it, then cut them to the "User Data" folder.


4. Okay, now we do the same thing to the Chrome shortcut. Right mouse click on your Chrome shortcut (desktop), then "Create Shortcut". A new Chrome shortcut will appear there. Right mouse click again on the new Chrome shortcut, then click "Properties".
A new window will pop up, change the target to this :

For Windows Vista & Windows 7: C:\Users\AppData\Local\Google\Chrome\Application\chrome.exe –user-data-dir="\User Data\MW99"
For Windows XP: C:\Documents and Settings\User\Local Settings\Application Data\Google\Chrome\Application\chrome.exe –user-data-dir="\User Data\MW99"

Or simply, just add {space}–user-data-dir="\User Data\MW99" to the end of target box. Don't write the {space} just push the space button :D


So now I have 2 profile of Chrome here, each shortcut has different cookies.
