Password Protect Folders in XP
To password protect a folder built into Windows XP (for other Windows flavors, there are some freeware/shareware programs out there).
If you have a log in password for your account, this can be used to protect folders from other users. If not, you need to creat one. Your hard drive must be formatted using NTFS (which it probably is unless you're dual booting with another operating system). Here's what to do...
Right-click the folder that you want to make private and choose "Properties" (or Alt+Double-click). Go to the "Sharing" tab and check the "Make this folder private" box.
Click Apply . If you do not have a password on your account, a box will pop up asking if you want to assign a password. This must be done if you want to make the folder private, so click Yes . You will need to use your password to log on to your computer from then on.
Type in a password then confirm it. Click the "Create Password" button then close the Password window.
Click OK in the Properties dialog box.
Now anyone else logged on to your computer can't access that file without knowing your password.
