Sometimes we have important files that we don't want to share with others.
But, how if people accidentally find those files and duplicate or sent them to their portable storage.

To avoid above condition, simply applying this simple tip and the copy paste function will be unavailable.

Here are the steps:
1. Click Start>Run>type regedit then ok
2. Click HKEY_LOCALMACHINE>SYSTEM>CurrentControlSet>Control
3. Right click on Control choose New>Key then name it StorageDevicePolicies
4. Right click on StorageDevicePolicies then choose New>DWordValue then name it WriteProtect
5. Double click on WriteProtect, then change its value to 1
6. Then restart your computer

If succeeds, Error Copying File or Folder warning will now appear when trying to copy paste files

To return to default condition, simply change the value become 0 again.
