right click, properties on the chrome shortcut you will be using and add the above after the target, remember the space after chrome.exe(space here)--user-data-dir="D:\Temporary Internet Files"
Now you can delete the old Chrome user folder.
Now that I am a proud owner of a marginal ssd, I am concerned about such things.
Any page that loads except from the shortcut has no extensions or bookmarks. Not quite sure about the behavior but no second cache seems to appear. You would think these programming geniuses would be able to fix this and allow relocation of the temp folder like Internet Explorer.
