But the indirect repository ignores the FAT links. `git status` or `git-annex status` do not see them, nor does `git-annex find`, `git-annex info` or `git-annex whereis`. They all act as if those files were not there. + +I thought that maybe if I removed file C, and ran some `git-annex sync`, the repository on my HDD would notify its companion that it had a file called C, and the new correct symlink would be created now that there was no conflict with the file name. So I did a simple `rm C` and one `git-annex sync` on each repository. What happened was that file C got deleted, and I had to dive into the `git-annex unused` to get it back, as it was my only copy of it (I wish there was a way to see the filenames on that output, but I made it!). + +I also tried `git-annex fix` on one of these FAT links, but it appears to fall outside of its competences (or it simply does not see the file, like those other commands). `git-annex fsck` skips these files too, BTW. + +# Now what? + +In total I have several hundreds of files in this situation. Maybe there is some simple or proper way to convert these back into the real symlinks they ought to be. I don't have the time to go into scripting mode to *try* to fix this issue, so I try to gain some guidance from those who know more than I do. + +I don't know how these FAT links came about. I did have some problem [like these reported here](https://git-annex.branchable.com/forum/files_got_replaced_by_broken_symblinks__44___how_to_get_them_back__63__/). If I recall correctly, in a direct repository in a FAT filesystem, running `git-annex drop FILE && git-annex sync` would replace FILE by a FAT link, and then this error would propagate to the other indirect repository. However, this is not the problem I am experiencing, since the original files are fine. +Where should I go from here? + +I just noticed that `git log` has something to say about these FAT files. Maybe it helps *someone* to trace the origin (I can't decipher git-annex's logs yet).
