Thanks for the suggestion. I was working on getting the list
for you when I decided to first try and reproduce this on
Linux. I was not able to do so. Then I opened the Linux File
Explorer and went to one of the files. There were two files by
that name, with names differing only by case.
In windows, I only saw one, because Windows Explorer only
supports one file with an identical case-insensitive name per
directory. Unsurprisingly, that is also the one that was
selected by getSize(filename). The underlying windows functions
must ignore case as well and select the same way as Explorer
(which makes sense). That explains why Windows Explorer
reported the same size as getsize(name) in every case, while
DirEntry.size would match for the file with the same case as
windows recognized and not for the file with a different case.
I was able to get into this state because I copied the files
(merged directories) in Linux.
It was interesting to look into. It seems everything is working
as designed. It shouldn't be an issue for me going forward
either as I move more and more towards Linux.
That's hilarious! I'm happy you found it.
