directory and file names with blank spaces

[Stephen Curran]

I have been using Y&Y Tex version 2.2 on both office and home computers.
I have run into the situation that when a directory or file name of a
TeX file that I want to convert to a DVI file contains a blank space,
Y&Y Tex cannot find the file. It tries to append .tex to the first
occurrence of a directory name or file name with a blank space. When I
enter the file name after the prompt, it produces a DVI file as
expected. I find this incredibly annoying. I have the luxury of  using
underscores instead of blank spaces in directory or file names on my
home computer. This is not the case for my office computer. The tech
support staff have all staff and faculty store files on a directory
named "My documents and files" for remote backup purposes.

How does one resolve this problem?
