Initially, I tried demo for Password-find for free and it gave me the demo-file, so I was sure that the file could be unprotected before I buy the license. Just in $20 I get lifetime license key and now I can unprotect my unlimited MS Office files. I assure you, password removal process is very fast and reliable. Password-Find has unprotected my file and protected my job and my days of hardworking. Many thanks...
