Incremental Compile: When we select a single object (BC, Applet etc), several objects (Multiple BC, Applets, BO etc), single project or several projects to compile in an existing SRF file that is known as Incremental Compile.
Full Compile: When you compile all the projects in a SRF file that is known as Full Compile.
SRF File: We do an Incremental compile on an existing SRF file and Full Compile results in creation of a New SRF file.
SRF Size: SRF size is more when we do an Incremental Compile as compared to Full Compile. For example if a Full Compile results in a 28 MB SRF file then an Incremental compile on that file can increase it’s size up to 32 MB
