Mark, now you made me wonder:
What does FindAllFiles has to do with Lazarus?
Agreed. I would have expected the Function in the FPC-part of the docs, not the Laz-Part
It's not under the docs at
https://www.freepascal.org/docs.html which tends to be my normal reference for stuff that I don't know is GUI-related. It's at
https://lazarus-ccr.sourceforge.io/docs/ which has a separate copy of the RTL and FCL docs... which I'd presume pertain to the version of FPC currently with release/stable Lazarus (which might lag release/stable FPC) rather than being a straight duplicate... looking at HTML and sourcetree dates suggest Lazarus docs are still 3.0.2.
I've certainly asked about the distinction between RTC and FCL packages in the past, and was told that it was pretty arbitrary. I'd presume that FileUtils etc. is separate since Lazarus is in theory at least a separate project from FPC with different contributors.
In any event, my Lazarus documentation browser tab was for the LCL, so was one level more specific than was really useful... now fixed :-)
