After running a "Deep Scan," it found not only the recently lost file but also old archived spreadsheets I had deleted months ago. The relief was immense. It successfully restored the core files I needed, and they opened perfectly without any corruption. And it is incredibly easy to use, I didn't have to configure any complicated settings, which was a huge plus in a stressful situation. Review collected by and hosted on G2.com.
To be thorough, the deep scan took some time, 28 minutes on my Mac. While I was amazed that it quickly located the recently lost file in the first several minutes, the whole scanning took longer. Maybe it was just a configuration issue. Review collected by and hosted on G2.com.
