Explanation :
FOCA is a free, GNU-licensed tool that gathers information by scraping metadata from Microsoft Office documents, which can include usernames, e-mail addresses, and real names. Note that while FOCA can be run in Linux and Unix variants using WINE (a compatibility layer or interface that allows Windows applications to run on *nix operating systems), the question specifically mentions that the tool was written for Windows, rather than stating that it only runs in Windows.
While Maltego and recon-ng are capable of scraping metadata from files with the use of transforms or modules, neither of these tools was written specifically for the Windows operating system family. Theharvester is limited to what can be pulled directly from a website; scraping the contents of files stored on a website is beyond its capabilities. In addition, theharvester is like Maltego and recon-ng in that it was not written specifically for the Windows operating system.
