Git log doesn't work with path unless file is in current directory

Question

I'm using Mingw-w64 on Windows 10 and trying to see the git log of a single file. If I cd into the folder containing the file and use:

git log -- file.txt

it works fine. However if I'm in the folder above and try to use any of the following, it just returns nothing:

git log -- folder/file.txt
git log -- /c/full/path/to/folder/file.txt
git log -- folder\file.txt
git log -- folder\\file.txt

I've also tried putting a backslash in front of the -- but to no avail. Exactly the same happens with gitk.

Answer 1

I think I've found the answer. file path arguments are case-sensitive even when the core.ignorecase config is true. I was typing the file and folder names in lower case which seems to work with 'ls' and other mingw commands but not with git.
