If you want to keep a highly confidential file, keep it as hard copy in the safe.
if you want to keep a moderately confidential file, this is what I recommend.
Convert file into PDF format and protect it with encryption. Acrobat 9 now supports 256-bit Advanced Encryption Standard (AES) as approved by the U.S. government.

Then keep it in a folder by applying strict Windows security (assuming you are using Windows Vista).
First of all, make sure you have a login to Windows.
Assign the login with full control.

So now you have a folder where only your login can be able to access, modify and delete it.
This will help to prevent the following threats.

So now you have a folder where only your login can be able to access, modify and delete it.
This will help to prevent the following threats.
- Other registered windows users - Will not be able to gain access to the folder.
- Malwares (while you logon as yourself) - By turning off access to administrator, system and other users. (Malwares would usually try to gain access to the folder using system or administrator rights)
- While the laptop or hard disk is stolen - all folders can be opened now. The only protection is the security for PDF file.
- When selling your laptop - make sure you fully clean up the hard disk or replace it with a new hard disk. Still the PDF file is protected by password.
Anything that is electronic is not 100% secured.
