Folder Lock

Everybody really want to hide their data from others at office/home. I got lots questions regarding how to lock folder and make it private. I have seen so many same question on Yahoo! Answers too. There was a trick in Win 98 where you customized folder and locked but it was too old. Mostly all people use Windows XP and Windows Vista nowadays. There are many third party software like Folder Guard, Folder Lock, My Secret Folder etc available in market. They lock your personal folder and hide your data from others. But, you need full version of those third party software which does cost to you. Well, I found a cool trick to lock folder and hide your data without third party software. It is nothing but just a .bat (batch) file trick which creates a folder named 'Locker' on same directory when you open .bat file with following text in it. So, if you want to lock your data then open Notepad and type following text or copy|paste then save it with .bat file extension.

Don't forget to insert a password in place of text 'YOUR PASSWORD HERE'. Then simply run that .bat file. It will create a folder named 'Locker' on first run. (Please see following screen shot)


Once you get 'Locker' folder then save|copy-paste whatever you want to lock|hide from others. in 'Locker' folder. Now again make double click on .bat file.
