In this application I'm populating a stringlist with a list of files

The only way is reading the entire directory in memory, and then
performing your own case-insensitive search on that. The compiler does
the same (see compiler/cfileutl.pas -- or do not look at it, depending
on the license of your program, since that code is GPL). The big
downside of this approach is that it can introduce very noticeable
delays in your program's operation when working on networked file
systems (especially if there are lots of files in a directory).
Yes, I've done it this way previously (and even in another component of this software). I just
wondered if there was a better way. OSX can be a little slow over the network sometimes, but it's
not proved a big issue.
I think the only real solution is accept that different OSes do not
behave exactly the same, as this will by no means be the only difference
they'll encounter. You will not be able to "fix" all of them, unless you
start really emulating one OS on top of the others (in which case you'll
alienate the "native" users of that platform). And almost every single
one of those changes will make your program slower, harder to maintain
and harder to port.
Unfortunately this software is being used by people who tend to transport their data from platform
to platform, and they expect the software to be bug for bug compatible across all the platforms.
I'll just have a play with making the case insensitive search as efficient as I can and leave it at
that. I have different key maps across the platforms, serial handling is also different, but things
like file names are a sticky one. People expect to share one directory on a server and access it
from the three platforms and get the same results.
Thanks for the advice :)
