.compiled compilation session for a project
.ico program icon
.gitignore list of files/directories to be ignored when using git
.res compiled resource file


Subversion or Git

These files would normally be stored in a repository as an adequate description of a project:

*.lpi
*.lpr
*.lfm
*.pas
*.pp

These files might contain manually-generated or imported information, or might be regenerated by the IDE or build process. In general, if they have the same basename as the project or a form or unit they're IDE-generated, but in all cases should be reviewed individually:

*.inc
*.res
*.lrs
*.rc
*.ico

These files are regenerated by the IDE or by a build so do not need to be stored:

*.ppu
*.o
*.a
*.lps
*.or
*.rst
*.compiled

There is an example .gitignore file at [1].

Delphi
