We have a habit, especially when working on shared use computers, to protect our documents through the use of a password, but sometimes we do not easily remember the password used so we cannot directly access the contents of that file.
If you don't want this to happen again, then you need a tool like Office Multi-document Password Cracker. As the name implies, Office Multi-document Password Cracker is an office application that allows you to open MS Word and MS Excel documents even if they are password protected, working for versions 97, 2000, XP and 2003 of both programs.
Office Multi-document Password Cracker allows you to open several files simultaneously (although it does not provide the hidden password, it simply opens them).
You can free download Office Multi-document Password Cracker 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
