Hello, you were right, I didn't give enough details (it was 3:00 am for me :)). Anyway I resolved my problem : I wanted to launch something like "C:\Program Files\Pilot_Install_4.0\Pinstall.exe C:\WINNT\Temp\temp_0123456.txt". So I tried to translate the path of the exe in cygwin paths, or the path of the argument, or both, but nothing seemed to work. Finally I understood!!! The program needs a DOS path, even if it is launched through cygwin. And , Here is the tricky thing, the argument is parsed by cygwin, so : "/cygdrive/c/Program\ Files/Pilot_Install_4.0 c:\WINNT\Temp\temp_0123456.txt" does not work But "/cygdrive/c/Program\ Files/Pilot_Install_4.0 c:\\WINNT\\Temp\\temp_0123456.txt" WORKS!! The "\\" are interpreted by Cygwin as "\" and are needed for Cygwin to pass an "understandable" path to windows. And trickier, I use several strings in my program to build this command line, and so, there is a second interpretation of the string. So the string I must use to build this command line is : "c:\\\\WINNT\\\\Temp\\\\temp_0123456.txt" Anyway thanks for help.
