Many of my friends who are IT professionals avoid spaces in filenames and directory names, because you'll never know when they will cause problems.

To satisfy our human need for readability, underscores are the next best thing to spaces.

RENAME ISNT AND OPTION because files are on network drive and other programs already are configured to this.

And re-configuring those programs reallly wasn't an option? If the mountain will not come to the prophet, the prophet must go
to the mountain.
