To permit another user to access your files, click Add to show the Encrypting
File System window.
Now, you won??™t necessarily see all the user accounts on your PC here, only
those that already have security certificates. If you don??™t see the account you
want to include here, you??™ll need to log in to that account and encrypt at
least one file or folder.
If the user doesn??™t have an account on your PC, you can either create one, or
you can install the user??™s own certificate on your PC by hand. To do this,
ask the user to send you the certificate from her PC. Then, open the Start
menu on your PC, type certmgr.msc, and press Enter to fire up the Certificate
Manager. Expand the Personal branch and then select the Certificates
folder. From the Action menu, select All Tasks ??? Import, and then complete
the Certificate Import Wizard by following the prompts.
Note that the Expiration Date shown here represents the date the user??™s
security certificate expires, and has nothing to do with the permissions
you??™re setting up. No hurry, though; you??™ve got at least 100 years.
