Advice
- Do not change the names of files in the protected folder. Otherwise, they will not be protected.
- Store your password in a safe place.
- If you copy the batch file code directly from the WikiHow page (in edit mode), remove the "#" and spaces at the beginning of each line.
- Windows search engine can find the protected folder.
- Hide the files so they do not appear in Windows Explorer.
Warnings
- An experienced user who understands batch files can find out the password. If you want to reliably protect your data, then encrypt it.
- Programs like 7zip can access the folder.
