Solo, you don't save it, it's not a file. You give it a folder for it to keep in sync between us. I think you have given it some sort of general folder, as I have all sorts of random stuff from somebody.
(Did not poke around to find out whose, and I suggest everyone do the same.)
Delete the entry in your syncthing control panel, and then try again, sending it to an empty folder.
http://docs.syncthing.net/intro/getting-started.html for everyone's reference.
Nobody delete ANYTHING in their folders until Solo reports back as it would then delete the file on Solo's side.
( /me is embarrassed that such a guffaw happened.)
That's likely me, for some reason it saved into my documents folder, not an actual, independent folder (yes, I typed in a new folder for it to be in, but it didn't generate a new one). If so, there should be documents like"My Kindle Contents" and "Fax" and "Scanned Documents". It should change, as I've removed the connection and made a new one to a folder prepared beforehand, and it's been successful. If it's mine, just delete all the left over stuff when you want to, it's not shared with you guys anymore and won't affect my own files.
Sorry about that, if it was me.
Edit: Yup, all mine. Sorry that you got the blame, Solo.
Edit 2: Also, I deleted it yesterday before going to sleep, I suppose I wasn't quick enough. :/
