file types

This page is a summary of the file types created by FPC and Lazarus. The main purpose is to make it easy to find out whether or not a particular file should be added to a Version Control System (VCS) like SVN or Git.

Types to add to VCS

.pas

.pp

.lpi

Lazarus project information file. Created by Lazarus for every new project.

.lpr

Lazarus program (or project) file. The source code of the main program. Analogous to Delphi's dpr project file.
