File Locker

I have a DS Firelink card and i want to put a file on there where it asks for a password before anyone tries to remove/outs new files on...

Can someone suggest me a program

 

you can use winrar to password protect files

 

Thats just for files inside the actual .rar file yes?

Try Steganos Security Suite.

Nothing on file locking =\

 

Hmm, you can just make the file hidden?

Would that work?

Or you can make it so, your the only person that can read the file, [I think]

Right Click the file >> Properties >> General >> Advanced >> Check "Encryption content to secure data", and tada. I think that makes it so, your the only used/ Computer name that cant open the file.
