Introduction

FastReport Viewer is a free software for viewing files produced by the FastReport report generation systems.

FastReport family

The FastReport generators are developed by Fast Reports Inc. The first product was released in 1998.

FastReport generators can be connected to various DBMS or other data sources, including those generated directly in the code of an application. The report generator can perform various sorting, grouping and filtering operations on the input data to get the desired result.

FastReport generators are used in software development as additional modules that can be used by developers to implement the necessary functionality for generating documents, printing them and saving to files of different formats.

All FastReport generators can save prepared reports in their own formats (prepared report - FPX or FP3).

The following table lists the formats and the generators that generate them.

Extension (format)	Development platform	Report generator
FP3	Deplhi VCL/FMX/Lazarus, C++ Builder	FastReport VCL (Lazarus), FastReport FMX
FPX	.NET Framework, Mono, .NET Core, .NET 5, .NET 6	FastReport .NET, FastReport Mono, FastReport Open Source

In addition to libraries for embedding into the software under development, Fast Reports produces products for end users to connect to data sources, generate reports (documents) and save them to files in various formats:

• FastReport Desktop - software package to automate the development and construction of reports, includes a scheduler;
• FastReport for DBA - is a software package for database administrators that includes a scheduler and a report manager.

The programs listed above can generate files that can be viewed with the FastReport Viewer. They also contain viewers bundled with them.

Also supported file formats can be generated by web applications that use the products:

• FastReport VCL Enterprise;
• FastReport .NET;
• FastReport .NET Core;
• FastReport Open Source.

Package Contents

Let's look at the package of FastReport Viewer for the Windows operating system (the package for other operating systems may have different file names).

The installation folder contains the following files:

Fine	Purpose	Supported file formats
FormatSelector.exe	A program to determine the file format and automatically open the desired program for viewing. The program registers in the system for all supported file extensions.	FP3, FPX
FastReportFMX_Viewer.exe	Prepared Report file viewer for FastReport FMX	FP3
FastReportVCL_Viewer.exe	Prepared Report file viewer for FastReport VCL/Lazarus	FP3
Viewer.exe	Prepared Report file viewer for FastReport .NET/Mono	FPX

Attention! The FP3 file formats of the report generators for VCL and FMX differ in structure. It is recommended to use FormatSelecor.exe program to switch to the desired viewer.

Limitations

The file viewers included in the package can only view files. They cannot print and save files (convert) to other file formats. If you need to print or convert prepared report files - contact the developers.
