Disable mounting of external storage

When this policy is set to true, external storage will not be available in the file browser.

This policy affects all types of storage media. For example: USB flash drives, external hard drives, SD and other memory cards, optical storage, etc. Internal storage is not affected, therefore files saved in the Download folder can still be accessed. Google Drive is also not affected by this policy.

If this setting is disabled or not configured then users can use all supported types of external storage on their device.

Supported on: SUPPORTED_WIN7
