Note that *.lrj files are generated for every form while tracking i18n, loss of these files can cause missing translations.

File extensions

Some file extensions

Lazarus

Project files

extension description
.lpi Lazarus Project Information file (stored in XML; contains project-specific settings)
.lpr Lazarus Program file; contains Pascal source of main program
.lfm Lazarus Form file; contains configuration information for all objects on a form (stored in a Lazarus-specific format; the actions are described by Pascal source code in a corresponding .pas file)
.pas Unit with Pascal code (typically for a form stored in a corresponding .lfm file)
.pp Pascal code
.lrs Lazarus Resource file (this is a generated file; not to be confused with a Windows resource file).
.ppu Compiled unit, symbols part.
.o (1) Compiled unit, code part.
(2) Compiled code from other compilers (e.g. gcc)
.or object resource, automatically generated from {$R} directive.
.a (1) Compiled unit, code part for smartlinking (on some platforms)
(2) Compiled code from other compilers (e.g. gcc) linked into a static library
.lpk Lazarus package information file. (stored in XML; contains package-specific settings)
.inc Include file
.lps Lazarus Project Session file. See Project Options Save session information in
.lrt Lazarus Resourcestring table created when saving a .lfm file and i18n is enabled. It contains the TTranslateString properties of the .lfm.
.rst Resourcestring table created by the compiler for every unit with a resourcestring section.
.rsj Resourcestring table in JSON format created by FPC 2.7.1 for units with resourcestring section.
.compiled compilation session for a project
.ico program icon
.gitignore list of files/directories to be ignored when using git
.rc resource file
.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

Note that *.lrj files are generated for every form while tracking i18n, loss of these files can cause missing translations.

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