DiskCacheDir text Description
Setting the policy has Google Chrome use the directory you provide for storing cached files on the disk—whether or not users specify the --disk-cache-dir flag. If not set, Google Chrome uses the default cache directory, but users can change that setting with the --disk-cache-dir command line flag. Google Chrome manages the contents of a volume's root directory. So to avoid data loss or other errors, do not set this policy to the root directory or any directory used for other purposes. See the variables you can use ( https://www.chromium.org/administrators/policy-list-3/user-data-directory-variables ). Example value: ${user_home}/Chrome_cache
