Since gergn took some time checking this out, posting on the download page, and seemed interested, thought I'd check it out. BTW, in case you're interested, DiskGenius, an app I've used very occasionally, can read the Linux file system, though only small files can be copied unless you buy the Pro version. There is a free version & portable version.

Password Folder is a small app -- <10MB -- that once run, including the portable version, adds itself to Windows Explorer right-click context menu. That and an uninstall key are all that are added to the registry when the app's installed. The portable version adds a single file to the hard disk, ProgramData\pfonce.ini, while the installed version adds the app's folder to Program Files (x86), and 3 different 1KB files to Users\ [UserName]\ AppData\ Roaming\. The portable version will not activate with the given key, but will recognize that the installed version has been activated, and will be unlocked. When you protect a folder a restricted access folder is created, C:\ pfdocument.. , which holds the protected but unencrypted files. When you protect a folder a new file takes its place with the same name as the now protected folder and a file name extension of .pff . Double clicking that .pff file brings up a small dialog to enter the password -- once the correct password is entered the original folder is recreated using the files stored in pfdocument.. . Whether it contains any files or not that folder will remain in place, and because it's protected you can't delete it. That folder is visible in Windows Explorer, using the same or a different copy of Windows, though it is not visible after booting to WinPE, so it *might* not be visible if you boot to a Windows-based alternative with a command prompt, e.g., utility or backup app USB sticks. However, booting to a Live Mint Linux XFCE ISO I could access pfdocument.. like any other folder, and copy the contents to another folder. I could of course also delete the folder if I wanted to. I had protected a small app, MyDefrag, and after copying the files out of the protected folder and booting back to Win11 that copy of the app worked fine.
