[@LoyalCustomer] You are not doing anything wrong. We added this feature in as a safe guard for our users. There is nothing worse than locking a file and forgetting the password seconds after you locked the file. With that said, there is a simple process for deleting the original unlocked file. First you can use the “Secure Delete” function of the software. Simply drag and drop the unlocked file into the file box under the “Secure Delete” tab of the software. This will securely delete the unlocked file from your hard drive, and will be completely unrecoverable. Second, you can go to the “Options” tab, and select “Delete Original Files after Locking” This will automatically delete the original file after you lock a file.
