Long Filenames with spaces

["Sterling Lumpkin" <kulumsw@hom.net>]

I'm using Pi3 with the enhanced interface.  Everything is working great except for one thing which is wreaking havoc.

I use Directory Indexing heavily to pass files between sites.  
Local users can post to the web via the LAN, and my remote users can post via FTP.  Pretty much everybody checks the website to see if any new files have arrived.  The problem I am running into is that Pi3 can't handle the long filenames with spaces, and no matter how many times I tell my users not to use spaces in thier filenames, they just don't get it.

I've been trying to find a work-around, but can never get heavily into solving it. Unfortunatly, I was thrown into the job of administrator with no training and 40 systems (NT, Win 95, UNIX, and Alpha) which I do all maintenence on.  In short, I spend 90% of my time just trying to keep things running, and the rest trying to catch up with the massive backlog of work or figure out what the heck I'm doing...

I am hoping there is a solution which would allow me to continue using the Enhanced interface (and all of my current settings).  The reason being, I'm leaving in about a year and will probably have less than a month to train my replacement (who will in turn probably not have any training).  Simplicity is critical since I can't make any bets on my replacement's knowledge level.

I've enclosed the error below.  This one came from my home system, where I've installed Pi3 as a test ground.  The error at work is exactly the same, just different filenames...
