+I was git-annex-adding a folder of big files.
+I ran the command while inside a folder I didn't need anymore.
+I deleted the folder with nautilus (moved it to trash) which caused the cwd to change and that really confused git-annex.
+
+Root of repo is audio-recordings/
+
+While inside audio-recordings/a I ran `git annex add ../audio-files`
+
+Then I deleted audio-recordings/a with Nautilus which caused its path to change to /.Trash-1000/files/a
+
+As soon as git-annex finished hashing the file it was hashing, this happened:
+
+```
+add ../audio-files/moto-maxx/2018.04.17 1438.wav

+The file that was being added was left like this:

+
+It appears git-annex just chmoded it, but didn't symlinkify it.
+
+### What version of git-annex are you using? On what operating system?
+
+Ubuntu 20.04 focal
+
+Linux 5.8.0-050800-generic #202008022230 SMP Sun Aug 2 22:33:21 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
+
+git-annex version: 8.20200226
+
+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+I am absolutely in love with it. I even built a special remote for it and I'm now building another because that one was stupid.
+
+Seriously, git-annex is amazing.

+I found out how to do it after reading his source code for the [Google Drive remote](github.com/Lykos153/git-annex-remote-gdrive).
+
+Feel free to have a look around my remotes <github.com/cardoso-neto/git-annex-remote-manytars> <github.com/cardoso-neto/git-annex-remote-manyzips> which use his [helper module](github.com/Lykos153/AnnexRemote).
+
+To summarize it, you should override __init__ and list your configs there.
