2. Use a program to open it

There are different programs used to encrypt files which add the .encrypted extension at the end of the file’s name. The encrypted files can be open, but you’d have to use those programs that encrypted them to open them.

If you find that the encrypted file was created using one of these programs, or another program, use it to open the file.

3. Convert the file then open it

If you used EasyCrypto to encrypt a file, you won’t be able to convert it to any other format as the program doesn’t give a way of converting the files. However, if you have any files that you want converted, and they’re inside the .encrypted file, decrypt them and then use a free file converter to change them.

4. Take ownership of the file or folder

The owner of a file or folder controls the permissions set on the file/folder and to whom these are granted. The take ownership permission, or restore the files and directories user rights are the minimum requirements needed to perform this procedure. To do this:

  • Open File Explorer and find the file or folder you want to take ownership of.
  • Right-click the file or folder, click Properties
  • Click the Security
  • Click Advanced, and then click the Owner
  • Click Edit, and then do one of the following:
  1. To change the owner to a user or group that is not listed, click Other users and groups and, in Enter the object name to select (examples), type the name of the user or group, and then click OK.
  2. To change the owner to a user or group that is listed, in the Change owner to box, click the new owner.

Note: You can change the owner of all subcontainers and objects within the tree, by selecting the Replace owner on subcontainers and objects check box. This is optional.

An admin can take ownership of any file on the computer. However, assigning ownership may require you to elevate permissions by using User Access Control.

A user who has the Restore files and directories privilege can double-click Other users and groups and choose any user or group to assign ownership to.

Note: The Everyone group no longer includes the Anonymous Logon group.
