How it works: The new app is a command-line tool, so you’ll want to be a little familiar with Window’s Command Prompt app. You can target internal hard drives and external ones, including SD cards. Technically detailed: You’ll use the commands shown in the screenshot above to target specific file names, keywords, file paths, or extensions on your hard drive. The sooner you do that after you accidentally delete a file, the better, of course. Files to recover: Microsoft says its file tool “Recovers JPEG, PDF, PNG, MPEG, Office files, MP3 & MP4, ZIP files, and more… from HDD SSD, USB, and memory cards.” It supports NTFS, FAT, exFAT, and ReFS file systems, but you can’t recover files from cloud storage, like Dropbox or OneDrive. Bottom line: With literally hundreds of third-party apps that promise to recover your files that could be malware, Microsoft’s official tool will at least make choosing a recovery tool much less stressful.
