Hi Roy
I didn't totally understand your answer/question but YOU SHOULD NEVER keep all of your fonts in the windows fonts directory! The ideal situation is to have only the required default windows fonts in that directory and use a font manager to move fonts in and out of your system when needed. If you use Corel, font navigator is included and it works great.
The more fonts you have in the windows fonts directory the slower your system will get. I have over 40,000 fonts on my system and at one time or another I have used most of them. I never used scanned type on any of my work, I recreate all text in the exact font required and it might seem like added work but in the long run it saves you a lot of time.
I keep all of my data for all jobs in a folder called data (smart of me huh?) In that directory I have folders for all of the different programs that I use and a directory for fonts. In the fonts directory I have alphabetical directories and store all fonts in that order. My system fonts folder never has more than 200 fonts but my system sees between 700-900 fonts at all times. Using my data all in one directory makes backup very easy also, every night the data directory backs up to 7 different computers and I always have a backup. Works great, takes a little extra effort when you set it up for the first time but well worth it. I never have to remember where the data for a particular program is.
