When moving sketches to a folder, I received an error and lost my sketches

I am using windows 10 and Chrome Version 79.0.3945.117 (Official Build) (64-bit).

I was doing some folder management and created some new folders. When trying to move some sketches into one of the folders an error briefly popped up and disappeared before I was able to read it (couldn't get passed error and string of numbers). After the error disappeared the folders showed that only some of the files had been transferred. The files that did not get transferred into the new folder were nowhere to be found. I believe they have been lost. Does anyone have any suggestions on how I might recover the seemingly lost files? Only one of them is critical and it's one of the most recently saved ones.

Have pushed this up to the team for you.
Hopefully they will be able to recover you sketches.

Bob.

Thanks. It appears that most of the sketches have found there way back where they belong after some waiting and reloading. I still seem to have lost the most recent file though. I have a sketch that matches the name of the one I want, but it is missing a significant amount of code. I have already started to rewrite it manually but if there is a way to recover what has been lost, that would be incredible.

I took the liberty of contacting you via email.
