How To Move Chrome's Cache Files To The RAM Disk

Google Chrome is already in its 40th version and counting, and Google still refuses to provide the ability to change Chrome's cache size or location. There is a workaround using a command line option, which we will explain below. But before that, a warning...


Google Chrome stores the user profile in the same cache that is used to store temporary files used by the browser. This includes your bookmarks, history, cookies, etc.

Moving the cache to the RAM disk will therefore automatically wipe out not only the temporary files, but also your user profile. This is good if you want to automatically clear your browing history every time you reboot, but bad if you want to keep bookmarks to your favourite sites.

Do NOT use this workaround if you wish to retain your user profile.

  1. Identify the shortcut you usually launch Google Chrome with. This is usually a shortcut on your desktop, the Start menu or the taskbar. Because this is a command line option, you will need to repeat it for every Google Chrome shortcut you use.

  2. In this example, we will use the Start menu shortcut. Right-click on the Google Chrome shortcut and select Properties (the last option in the list).

Moving Google Chrome's cache

  1. This will bring up the Google Chrome shortcut's properties. Remember, any changes you make only applies to this shortcut, so you will need to repeat the steps for the other shortcuts.

Moving Google Chrome's cache

  1. In the Target textbox, add "--user-data-dir=" to the end of the command line, followed by the drive and folder in which you want the new cache to be. In this example, we wanted the cache to be stored in the Temp folder in the RAM disk (which is drive O), so we added "--user-data-dir=O:\Temp" to the end of the command line.

Moving Google Chrome's cache

  1. Click OK and you are done. However, the changes won't take effect until the next time you start Google Chrome, and only if you use this shortcut.

  2. If necessary, repeat the steps above for the other Google Chrome shortcuts you may use.
