Hi,

I have a problem: I changed my harddrives and order of drive letters. 
POV-Ray still starts, but it cannot find any INI files etc, as they are 
not on C but on drive F.

I also cannot find any longer the POV-Ray master Ini file. In the past, 
there was a button to load that INI file.

And I also searched the Windows registry for a place where I could 
correct the path, but the only path I found was only for scene files 
which I set to drive F.

How to make POV-Ray, when starting, searching for the files on drive F 
instead of drive C?

On windows unsure...

On unix based systems you can set an environment variable POVINI to 
point to an ini file setting up pointers to whatever directories you 
want. Unsure if the mechanism exists for windows POV-Ray installs?

On unix based systems it's also possible to symbolically link across 
file systems. Possible to point from a "C drive" directory to the real 
directory and files on the "F drive" by setting up a link.

I'd suppose similar mechanisms exist to do such things on windows 
systems - but I again don't know. Sorry.

Hi Sven - I hope you are in better health, spirits, and things are looking up.

My naive untested solution would be to look at / solicit feedback about / check
the docs for - where the files normally get installed, and then just change
everything to F: where C: exists.

(/media/oem/OS/ is the windows partition on my C drive)

executables are in: /media/oem/OS/Program Files/POV-Ray/v3.7/bin/
but I can't seem to find the directory with the ini files.
(This secret info ought to be written to a log and stored in a .txt file in the
user directory.)

I'd say for the present, just start searching the system for the filenames and
try to find out where they all are by brute force.

Can you provide a working example of how to do this with the Windows font
directory?  (use a dummy Linux directory as a surrogate)
I tried the symbolic link, but it doesn't really seem to work for me at present,
so it apparently still needs some small tweak.

I'm not completely sure what you're asking. Off the top of my head I 
don't know how to generically link from say the linux subsystem
on windows back into windows itself - though expect there is a way.

When I've used fonts not built into POV-Ray I've always copied the ttf 
font file into the working scene directory(1). So, I've created the 
scene below to try specifying the location of the font files in 
different ways including creating a symbolically linked directory in my 
/tmp back to my real personal font collection(see scene comment). All 
tests with current v38 master.

Surprised to find a full path specification of a font file didn't work. 
I always needed to extend the Library_Path to include the directory with 
the particular font - works even with the full path specifies to be 
elsewhere... Anyway the test scene follows. Hope some help.

Aside: On Debian based systems like Ubuntu there is a file called 
/etc/fonts/fonts.conf which lists the font directories on the system.
It should be your can add one or more of these with +L or via ini file 
edits once you find the ttf particular sub-directories with fonts you 
want to use. I now doubt full sub-directory tree structures are searched 
for font files - but not tried this.
