Drive letter: MSYS2 vs Cygwin?

[ghost]

Cygwin's drive letter: c:/. MSYS2's drive letter: /c/.

[sskras]

Actually c:/ works on my 1y old MSYS2:

$ ll c:/ | head -3
total 8596873
drwxr-xr-x 1 saukrs None          0 Jan 23  2022 $Recycle.Bin
drwxr-xr-x 1 saukrs None          0 Mar 11 12:28 $WinREAgent

$ uname -a
MSYS_NT-10.0-19044 DESKTOP-O7JE7JE 3.4.10.x86_64 2023-12-22 10:06 UTC x86_64 Msys

But yes, on Cygwin these virtual dirs are are located not in / dir, but in /cygdrive:

$ ll /cygdrive/
