Restore files that were saved in a deleted project folder

Hi, my case is a bit complicated. I used the harmony for manual lipsync. I created a lipsync in a word file, which I saved in the harmony’s project folder. However, when I finished, I merely exited the harmony program, and as I didn’t need the harmony project itself (only the word files i created), I simply didn’t save it. As a resulted, the whole folder was deleted, including the word files. The project folder in the recycle bin is empty, and each time I try to restore my data using previous versions or backups, it says “no previous versions / backups are available”, maybe because I use an SSD card.
Still, the word files did existed on my PC, so it’s hard for to believe that they’re completely impossible to restore. Please, any tip will be helpful.
Thank you, Renen.
