Greetings,

If u want to lock a file with a password then you can do so using winrar. Almost all archives support giving password, including WinZip, 7-Zip and it’s not something special with WinRar. Bt WinRar is more comfortable then any other.
And if you are setting access like this, it is better you set the compression level to “Store”, which will make the compression and decompression faster, since the main aim here is to set a password.

1) Right click on the file for which u want the password to b put.
2) Click on “Add to Archive”.
3) Then go to Advanced tab.
4)Click on set password…choose your password.
5) Click ok.
6) A winrar file with your filename will be created.
7) Next u may delete the original file, as you have now compressed it with a password.
8) Anyone trying to open the rar file won’t be able to, unless he knows the password.

So, no needs of folder lock software.
Enjoy your privacy guys….
