Is it possible to password protect folders?

Is it possible to password protect a folder (or folders) in Windows 7 somehow?

I have several possible uses for this. One of them:

At work all my colleagues and myself uses a common computer. On this computer I've installed Dropbox with personal files. Although we all have our own user account on the computer, we all are administrators, meaning everyone can, if they want to, enter my Dropbox folder. I'd love to have a password on this folder so that only I can open the folder.

Thanks

Thank you Rustberger,

That program was not exactly what I was looking for. I tried it and it did not let me work efficiently with my folders. For example I have to remember to lock the folders after working in them. It will not do so by itself after a given time.

Thanks for the help anyway!

How about something like TrueCrypt?

Here are a couple ways to do that without adding extra software:

Depending on the version of Windows, you can enable the built-in encryption (efs)

I use this program.

Assuming your username/password are secure, then...

RC on the folder you just created/Properties
SC on the Security tab, then “advanced”
‘uncheck’ the statement at the bottom of the dialog box which says ’Allow inheritable permissions, etc.
SC Remove
SC Add
fill in your user name
SC OK
SC “Full Control”
SC OK
be sure to delete "admin' permissions
close


Just be aware that if you forget your password, you're screwed. The admin can't help you.
