.pptx.icloud Unable to Open File

While trying to free up some space on my macbook, I uploaded many files and folders to Google Drive. Now when I try to access them, I cannot open them. They all end in either .pdf.icloud, .doc.icloud or .pptx.icloud. I uploaded the files a long time ago, so there is no chance of recovering them from my iCloud. I have also tried changing my Google Drive settings to convert upload to Google Drive format. I have also tried using keynote to open then. No luck with anything. I really need these files so any advise is greatly appreciated.
