What is .FTL file extension?
File used by FreeMarker, a Java template engine used to auto-generate text output; contains the source text as well as FreeMarker variable definitions and instructions that are used as placeholders for text substitutions; commonly used for auto-generating HTML Web pages, .JAVA class skeleton files, and other source code files, such as .PHP, .ASP, and .CFM files.
Two files are input into FreeMarker to generate a new text file: 1) the FTL template file, and 2) a Java file that loads the data used for the substitutions.
NOTE: FreeMarker is distributed as an open source Java package that can be embedded into Java software products. A popular Java-based product that uses FTL files is Alfresco, an Enterprise Content Management (ECM) system.
