Password Protect Folder

I have several Excel (and Word) files that have confidential data in and they are password protected, BUT it is a bit of a hassle to remember all the passwords.

Does anyone have suggestions on how to password protect a FOLDER so that i would have just one password to remember....yeah, i know i could change all the file passwords to the same password, just seems much easier to protect a whole folder.

I am using Win 8.1 and will upgrade to Win 10 as soon as it is available. Thanks

I doubt you could do this without delving into windows security.

However, zip files simulate file folders, and zip files you CAN password protect.
