I locked a folder containing some important files with an obscure application from SourceForge called Folder Lock Pro. When the enter password dialog came up to lock the folder I changed my mind, and as there was no close icon (x) I merely clicked OK. The application locked the folder anyway and when I tried to unlock it, no password dialog came up.
I had the folder open in a window when I locked it, so I was able to bring up the property sheets of the various files in the folder. They were all 0 bytes in length. However, when I checked the property page of the locked folder itself, the size seemed to be the same as before I locked it - 10 files 648 KB in total, so I guess they still exist in some form.
On further testing with non-critical files (something I probably should have done originally) there is an extra file in the locked folder, created by the program. I used the first method of encryption. The author is clearly not available (the last post is five years ago) and I'm not hugely tech savvy, so how could I fix this problem?
My OS is Windows 10 Home.
