Conversion methods

Delphi projects can be converted either manually or using the Delphi Converter wizard in Lazarus. Before beginning the conversion process, we need to note some considerations and information.

Filenames and extension

Filenames are case-sensitive on some file systems. When converting Delphi filenames, you should make your filename lowercase to avoid File Not Found error messages.

Lazarus and Delphi use different file extensions for corresponding units. The following table shows the correlation between the different file extension types:

Delphi	Description	Lazarus	Description
.pas	Delphi source file	.pas, .pp	Pascal unit file
.dfm	Delphi form	.lfm	Form data file
.dcu	Delphi compiled unit	.o, .ppu	Compiled unit
.dpr	Delphi project	.lpr	Project file
.res	Windows resource file	N/A
.dof	Delphi option file	N/A
		.lrs	Lazarus resource file
		.lpi	Lazarus project information
		.ppu	FPC unit description file
