For more about this weirdness, see: http://searchenterprisedesktop.techtarget.com/tip/0,289483,sid192_gci1204121,00.html If you would like your bash shell see the content of the real System32 folder, you can do the following: As administrator in a 64 bit cmd (NOT a bash shell): C: cd \Windows mklink /D System64 System32 Then you can access the real System32 folder via the System64 symbolic link: $ ls -l /cygdrive/c/Windows/System64/Defrag.exe -rwxrwx---+ 2 ???????? ???????? 232960 Jan 19 2008 /cygdrive/c/Windows/System64/Defrag.exe HTH,
