Both / and /cygdrive/c are correct in this case. The root directory for cygwin is the parent directory of the directory where cygwin1.dll is located. If cygwin1.dll is located in c:\tmp, the root directory for cygwin is c:\. Therefore, / is correct answer for cygpath -u 'c:\'. This is the same with the fact that c:\cygwin64\bin\cygpath.exe -u "c:\cygwin64" returns / rather than /cygdrive/c/cygwin64. > After copying those same files to C:\tmp\tmp: > > PS C:\Users\ttimo> C:\tmp\tmp\cygpath.exe -a -u "C:" > /cygdrive/c In this case, the root directory for cygwin is c:\tmp. Therefore, c:\ is outside of the cygwin directories. So, cygpath -u 'c:\' returns /cygdrive/c. -- Takashi Yano
