Password protetion to a file

Dear Freind


If you want to lock a file with a password then what you use ??????

Is it
Folder Lock or it may be any other 3rd-party unauthorized software????
Am i right?
I will Give you a better way
You can you use old win rar or win zip or even 7-zip software for this purpose
It is not something special with these software.

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 new password.
5) Click ok.
6) A win rar file with ur filename will be created.
7) Next u may delete the original file, as u have now compressed it with a password.
8) Any1 trying to open the rar file wont be able to, unless he knows the password.
So, no need of folder lock software.
If any problem feel free to ask
