retrieve password protected WORD file in memory stick

You will need a program to "crack" the password.

I recommend the passware products: https://www.passware.com/word/

If the password is anything other than a common name or a word that will be found in a dictionary, it is impractical to break modern (2007 or later) Office passwords.  The only way to crack a non-dictionary word is by brute force and there's not enough time left on this planet to do so with the computers we have today.

Any number of companies will sell you password recovery software.  They assume the password is a common word to be found in a dictionary, and ask you for what you can remember about it, and then work variations on the possibilities.  It's still not practical except for common words like "fred" and "passWorD".

"The 128-bit key AES protection employed in newer Office 2007–2010 remains secure. In fact, the distributed.net RC5 project has been trying to brute force an RC5 72-bit key since 2002, and as of 2013 has not successfully done so. Furthermore, even utilizing all known breaks (that speed up brute force attacks by a factor of about four) it would take a typical computer millions of years or longer to break a 128-bit AES key of sufficient length and complexity."

Also, it is against the policy of this forum to assist in hacking or hacking-like activities.
