I previously had about 200 .txt files saved in iCloud via TextEdit.
After installing the Yosemite (10.10), there is now a folder hierarchy in iCloud, and all my previous files seem to have disappeared.
I have looked in /Library/Mobile Documents — they're not there.
I have tried showing hidden files and looking through the Library with no success.
update – I have several Time Machine backups made well before I updated to Yosemite, but there are no documents in /Users/(username)/Library/Mobile Documents/(textedit folder)

I have 2 mac: 1 office running OS X 10.9, Mavericks, and 1 personal running OS X 10.10, Yosemite.
My files in OS X 10.10, Yosemite are not showing but in OS X 10.9, Mavericks they are still present.
Try logging in from another Mac running OS X 10.9 and you might find them there and be able to take a copy, as this is what I am doing right now.
