Unlike other Web browsers, Google Chrome doesn't provide a way to change the cache size from inside the program (as of version 43) but that doesn't mean it can't be done. By default, Chrome manages the cache automatically, making room as necessary while trying to avoid filling your entire drive. To override the browser's automatic behavior and set a manual limit on cache size, add the disk-cache-size switch to your Chrome shortcut in any version of Windows.
Specify Cache Size
Step 1: Open the Shortcut Properties
Right-click the shortcut you use to open Chrome and choose Properties. For shortcuts pinned to the taskbar, hold Shift while you right-click.
Step 2: Add the Switch
Click in the Target box on the Shortcut tab and scroll to the end of the line, past "chrome.exe." Add the text --disk-cache-size= followed by the desired cache size in bytes. Do not include commas or decimals. Click OK to finish.
- Multiply the number of gigabytes you want to use for the cache by 1,000,000 to estimate the number of bytes to set.
- Disk-cache-size sets the maximum cache size. If Chrome doesn't need as much space as you offer, it won't use all of it.
The disk-cache-size switch -- and any other shortcut switch -- only applies to the specific shortcut you modified. If you have Chrome shortcuts on your desktop and taskbar, add the switch to each shortcut separately.
Change Cache Location
To expand your cache beyond the space available in Chrome's default cache location -- the AppData folder on your system drive -- add another switch to the Target line. Type --disk-cache-dir= followed by a directory location in quotation marks.
- When you use several switches, it doesn't matter which order you type them. Just make sure each is separated by a space.
- To see a list of the pages saved in Chrome's cache, type chrome://cache in the browser's address bar.
