Directory name case (in)sensitivity on Windows

Case (in)sensitivity

You won't believe this!

Let's say that you make a folder in Bash on Ubuntu on Windows

bash -c "mkdir zZz"

As you may know, files on Windows are case insensitive, so you can:

dir zZz
dir ZzZ
dir ZZZ

All the same. But watch this:

mkdir zZz\x

After this the folder x in zZz is case sensitive and this is wrong:

dir zZz\X

Also it doesn't matter on the original folder name, because this is works:

dir ZzZ\x

Even if you rename/move the folder xXx the subdirectories stay case sensitive (but not the original folder itself).

casesensitive.cmd

bash -c "mkdir zZz"

mkdir zZz\x 

REM OK
dir zZz\x

dir zZz\X

mkdir xXx
mkdir xXx\x
REM OK
dir xXx\x

dir xXx\X
REM OK
dir xXX\X
