A non-quoted backslash \ is the Bash escape character. It preserves the literal value of the next character that follows, with the exception of newline. If a \newline pair appears, and the backslash itself is not quoted, the \newline is treated as a line continuation (that is, it is removed from the input stream and effectively ignored). So moving in dirs in the Shell its slightly different so if you want to walk thru dirs you shoud use / instead of \ as in *nix.

cd c:\   
# This is wrong and it will return c:
cd c:/   
# This is right and it will return c:\
cd c:\\
# This is also right and it will return c:\

The Shell uses a simple ini file called PTShell.ini in the PTSource directory as its RC startup it fully supports aliases and it reads by default as fallows :
