Increase FileSystem filter cache
 

Increase FileSystem filter cache:

To enable the file system filter cache, speeding up overall performance with file mangement:
HKLM\System\StorageManager\Filters\fsreplxfilt\Rep lStoreCacheSize = 4096 (DWORD decimal)
To return the file system filter cache to zero:
HKLM\System\StorageManager\Filters\fsreplxfilt\Rep lStoreCacheSize = 0 (DWORD decimal)
You can set the value to pretty much anything you like
