I have completed formatted my laptop,using a new win 10 os and permissions on my external hard drive have been deleted from the previous windows and and cannot access files!

Anytime I try opening files from that folder, Im told you don't have permission to view this file. Check the permissions and try again.

And also the files are encrypted and when I try decrypting it, it says that you will need to provide administrator permission to change these attributes.An error occurred applying attributes to file. Access denied.

  • External HDDs default ownership is set to Everyone. If you have ownership issues you will have to provide us the ACL in question, without that information, we cannot explain the behavior. However, if the files are encrypted, that changes everything. If you did not back up the certificate used to encrypt the files, then the files cannot be decrypted, even if you change their ownership – Ramhound Sep 30 '18 at 3:30
  • So what do I do now I don't have the certificate, cos I formatted the laptop completely before installing a new Os – Emmanuel Oduro Asamoah Qwejo Oct 1 '18 at 16:42

Run a command prompt with administrator privilege and try to the takeown command:

takeown /f directory /r

The /r for recursive.

  • Don't understand – Emmanuel Oduro Asamoah Qwejo Sep 29 '18 at 17:31
  • That changes the files to be owned by your user so you can change permission on them. – JOTN Sep 29 '18 at 18:14
  • It's not working, do I replace the directory with something else – Emmanuel Oduro Asamoah Qwejo Sep 29 '18 at 19:56
