Set disk cache size in bytes

Setting the policy to None has Google Chrome use the default cache size for storing cached files on the disk. Users can't change it.

If you set the policy, Google Chrome uses the cache size you provide—whether or not users specify the --disk-cache-size flag. (Values below a few megabytes are rounded up.)

If not set, Google Chrome uses the default size. Users can change that setting using the --disk-cache-size flag.

Set disk cache size:

Registry Hive	HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER
Registry Path	Software\Policies\Google\Chrome
Value Name	DiskCacheSize
Value Type	REG_DWORD
Default Value
Min Value	0
Max Value	2000000000
