What version of Vista? Even with hidden files (in XP, too) you can see files using the ATTRIB command. Your password is cleartext, and that is a bigger issue. Use the security of the OS.

What u mean by security of OS...I simply set the password textbox property Password Char to true..Is it not sufficient!!!!!

Not if you want to protect the data.

What version of Windows are you using???
