RAPPS, previously known as Download!, is a small program located in "C:\Reactos\System32" that allows users to download multiple programs without hassle.

It has its own application list that can be expanded by the user and the community. Applications that are included in the list by default are tested and most likely work on ReactOS.

How It Works

When you first start RAPPS, it will automatically connect to the internet, and it will seek for the file "rappmgr.cab". Then, it will extract the contents of this archive file to "C:\Documents and Settings\<user>\Local Settings", creating a folder called "rapps". The contents of the archive are just UTF-8 .txt files.

Every single file that is on download list in RAPPS, has it's own "description" file.

Custom files must be placed in /rapps folder created after .CAB file download. TXT file names should correspond to the software they are relative to.

It is suggested to test the text file before a PR, by pasting the document in /rapps folder and clicking "Refresh" in the GUI.

RAPPS also has experimental support for icons for application list. See Experimental Features for details.

Submitting New Applications

Some people may complain that his/her favourite application is not in the RAPPS list. The description files can be created by anyone. (See File Schema for a detailed breakdown).

Description files need to be saved in UTF-8 format (without BOM), or some specific languages will be displayed strangely. Also, line endings must be set as Windows format (\r\n). At the end of the file, there must be one empty line.

You can fork the https://github.com/reactos/rapps-db repository and send your submission as a Pull-Request.

File Schema

Here is an example description file.

 Name = My fun stuff-o-matic
 RegName = Name in Registry
 Version = 1.1.1
 License = GPL
 Description = Shortish description giving some additional background information about what it does.
 SizeBytes = 10485760
 Category = 5
 URLSite = https://example.org/
 URLDownload = https://ftp.example.org/pub/installer.exe
 Screenshot1 = Screenshot URL
 Icon = Icon filename in icons folder (with .ico extension)
 [Section.0419] ; 0419 - for Russian language
 Description = Description in Russian language

Let's analyze it from top to the bottom.


This is the beginning of the area that is read when the user clicks on the name of the program that he chooses to download. It consists of several things:


This is the program name that is displayed.


This is the version of the program.


The license that the program is based on. Typical options are : Trial, Demo, Freeware, Open-Source. Or more specifically, GPL, MIT and so on.


The description of the program giving some additional background information about what it does..


The actual size of the download in bytes. Used to display size value in the application info as well as while downloading.


The category of the program. Category name corresponds to the number. There are 15 categories for now:

  • 1 – Sound – Software for recording, playing, modify, convert sound
  • 2 – Video – As above but applies to video and movies
  • 3 – Graphics – As above, but graphics and images
  • 4 – Games and Entertainment – There are games, emulators for games
  • 5 – Internet and Networks – Browsers, IM clients, FTP software, Remote desktop...
  • 6 – Office stuff – Software that is used in the Office, for example, Open Office
  • 7 – Development/programming – programs used for compiling, and source writing, for example, Dev C++
  • 8 – Education – Programs that help in teaching, learning. For example dictionaries, translators
  • 9 – Engineering – Programs similar to CAD, SolidWorks (TM)
  • 10 – Financial – Programs for financial stuff, TRade monitors, database systems for warehouses e.t.c
  • 11 – Science – For programs that make simulations, helps in the Chemistry, Physics...
  • 12 – Tools – Utilities for users, for example, archiving software
  • 13 – Drivers – Files for the devices that are installed in the system
  • 14 – Libraries – Files that are needed to run some programs like Visual Basic and .NET
  • 15 – Themes - Themes for ReactOS or Windows (for example: watercolor, classic, luna, etc)
  • 16 – Other – programs that did not fit in above categories


Main web site where the program can be found.


Direct link to the installer/program.


Screenshot URL link. (N = 1, 2, 3 ...) Currently, only first Screenshot is used. Ensure the link is directed to the image, not a page contains the image (e.g. Imgur links).


Icon filename in icons folder (with .ico extension)


The specific language of the description, based on the host system language settings.

When host language is different than languages in the file, English is chosen by default (If you talk Spanish, and there is no such entry available in the file, software description will be displayed in English).

Locale IDs (that number in Section.xxxx) can be found here (numbers from the left column).

Experimental Features

RAPPS has some experimental features that are not refined enough and/or not used yet. They are still subject to change, therefore are not yet adopted in the main database.

However, these features are present in the codebase and work well enough to be tested and used.

Command Line Support

Apart from the graphical interface, RAPPS features command-line options that can be used to install apps. They will install exactly as if selected in the app itself.

Current available options are listed below:

  • /? - display the usage of RAPPS commandline
  • /INSTALL - accepts multiple apps as values and installs them if they are available.

Example: rapps /INSTALL 7zip akelpad

  • /SETUP - accepts a full path to the .inf file, where in [RAPPS] block you can specify which apps to install using one Install= key per single app.


Signature = $Windows NT$
ClassGUID = {00000000-0000-0000-0000-000000000000}


[Version] section is a nessesary header for .INF files. [RAPPS] is a section where you specify the needed apps. Apps should be added in .INF one-by-one, as can be seen in the example.

Names used are same as the filename in database textfiles.

  • /FIND - accepts multiple strings and find all corresponding apps contains the strings in the name or description.

Example: rapps /FIND Firefox "Python 3"

  • /INFO - accepts multiple package-name and display apps information correspond with the package-name.

Example: rapps /INFO rosbe codeblocks

Icon and Screenshot Support

RAPPS supports 'per app' icons, that will be shown instead of the generic 'application' icon. The icon can be specified with the field name 'Icon', which should be placed in the main 'Section'. The icon itself should be placed in the `icons` folder.

There is also support for a screenshot, which should be uploaded to an image host. This screenshot can be specified with the field 'Screenshot1'.

 Name = Code::Blocks (without compiler)
 URLDownload = https://download.sourceforge.net/project/codeblocks/Binaries/17.12/Windows/codeblocks-17.12-setup.exe
 SHA1 = 05ad095b5e04de243df736c060aea25a554dad94
 SizeBytes = 37372176

New [Section] Fields

There are two experimental fields in the database files - Languages and LicenseInfo.


This field is used to inform the user whether the app is available in their language.

You should place all the language codes app supports separated by | there.




This is a field in the DB which, when present, changes the way License field in the info is shown.

Application license types correspond to a number:

  • 1 - "Open Source"
  • 2 - "Freeware"
  • 3 - "Demo/Trial".
