Double backslash in filepaths ?

[Stef Mientki]

It looks like sometimes a single backslash is replaced by a double backslash,
but sometimes it's not ???
See the error message below,
the first backslash is somewhere (not explicitly in my code) replaced,
but the second is not ???
Is it in general better to use double backslash in filepaths ?

thanks,
Stef Mientki
