password / restriction / crypt / folder

[stereo]

I want to put a password / crypt / to restrict acces on :
C / users / username / AppData / Roaming / Yahoo folder
On my PC is no other users, i have no password ( and i won't have one )
Is there a way to do that ? Maybe a password ? I use Windows 7 Ultimate x64
Thank you.

If there are no other users, why would you want to protect this folder?

Be sensible and use a logon password - that's probably the best thing you can do. For more heavy fire power, try this:
