It matters if you comply with /C with "executable file name that includes Areas" and after that no other quotations. In that case, the prices will probably be preserved round the file identify Unless of course you employ /S. I extra a solution expanding on this.

An assembly language is unique to a specific computer architecture, in distinction to most higher-level programming languages, which can be more moveable.

@barlop, The purpose of /S is if you do not know beforehand whether the command has embedded quotes or not. If there are actually accurately two quotations over the command line it is addressed in different ways by default if you'll find accurately two quotation figures than if you will discover extra or much less. /S causes it to be be addressed precisely the same.

Is there some subtlety to /s that is eluding me? When would it not at any time be website important? When would it not even make any distinction?
