*.bpl and *.dcp files for Release and Debug configuration.

[dmitrybv 3]

Good day.
By default, when compiling packages in Release and Debug mode, the following files are created
*.dcu, *.bpl, *.dcp. If you enable generation of C++ files, then *.lib, *.bpi files are also created.

Usually *.dcu files are moved to the \$(Platform)\$(Config) folder
*.bpl files are moved to the $(BDSCOMMONDIR)\Dcp folder
*.dcp, *.lib, *.bpi files are moved to the $(BDSCOMMONDIR)\Bpl folder

But since the $(BDSCOMMONDIR)\Dcp and $(BDSCOMMONDIR)\Bpl folders do not provide subfolders for Release and Debug configuration, how does the IDE separate *.bpl, *.dcp, *.lib, *.bpi files for Release and Debug configuration?

You have that backwards.

It doesn't.  Libs that are shipped with the IDE are separated, but user-provided libs are not. So either separate them yourself, or don't have them both installed at the same time.
