# Projects

> Understand projects in ABBYY FlexiLayout Studio: FlexiLayout (.fsp) and Classifier (.fcp) project types, their contents, and how batches are stored.

A **project** is a set of files created in ABBYY FlexiLayout™ Studio and containing information about the [elements](/flexi-capture/fls/template/elements) and their properties, the [test images](/flexi-capture/fls/batch/image), and other project data.

## Project types

Projects fall into the following types:

* [FlexiLayout projects](/flexi-capture/fls/project/flexi-layout-project) – Used to develop FlexiLayouts that detect data fields on documents.
* [Classifier projects](/flexi-capture/fls/project/classificator-project) – Used to develop classifiers that group documents into classes.

Within a project, you build, test, and debug FlexiLayouts and classifiers.

A FlexiLayout project has the extension `*.fsp`. A classifier project has the extension `*.fcp`.

## What a project contains

A project includes:

* The descriptions of the elements (a FlexiLayout or a classifier).
* The batch of images used to create and debug the FlexiLayout.

The default storage location for the images you add to the image batch is `[project name]Batch`, and the default location of the FlexiLayout is `[project name]Template`.

To start working with ABBYY FlexiLayout Studio, create a new project or open an existing one.
