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!!!!!

[dglienna]

Not if you want to protect the data.

What version of Windows are you using???
