2. Save the file as lock.bat (.bat necessarily).
3. Start by double-clicking lock.bat and "MyFolder" folder will be created.
4. Copy everything you want to hide into the folder.
5. Start lock again.bat and when the message appears, press Y and <Enter>.

You will need to enter a password. By default password inventions, I think you can easily find where in the script it can be changed to your own.
Even if you set "show hidden folders", you will not see your hidden folder there. Tip: Do not store this script in the same place as the hidden folder, first of all, as you can see, the password in the script is stored in plain text. Copy it to the target directory when you need access to the folder. Well, rename it to something less provocative to run, for example, winsysup.bat or come up with something of your own.
