can't open gsheet

Question

I had 4GB on my gdrive space taken by files that were not there.. (there were many pics I was owner, but I didn't see them. I had to search them by name which I got from the person I was sharing it with :O : O...), It took ages, but I cleared some 95% of my gdrive that I found. 
At first, not to loose any of my important documents, I transfered my important folders that I wanted to keep to my hard drive on my MAC (in finder I simply have a gdrvie folder, so I moved it out)...
Later I moved the files back, but all the gsheets and gdocs -> yes these files that were so important that I backed them up not to loose them... they can no longer be opened.. on my disk I see a red exlamation mark and they simply won't even sync.. 
I have emptied my bin- How can I access these gsheets?
Thank you.. This is a really strange behavior and makes gsheet so insecure :O

I found a solution:
- I requested a recovery and within less then an hour the files were back (creating a mess on my gdrive)
- only possible max 25 days back, but at least I didn't loose the files..
