What is an RDM file?

RDM files mostly belong to Remote Desktop Manager. RDM files are not a single file type. The main version is the Remote Desktop Manager file used by Devolutions. This file is usually formatted in XML and stores connection details, credentials, and other settings for managing remote desktops. You can open these files using the Devolutions Remote Desktop Manager application.
Other versions of RDM files include:

• Dungeondraft Map Files: These use a JSON structure to save map data for dungeon layouts and game sessions.
• Game Model Files: In Anno 1800, an RDM file can store 3D model and scene details needed for game assets.
• Design Scene Files: Some RDM files act as Raindrop Geomagic Design Files for Ray Dream Designer, containing scene and design information.
• Raster Data Models: A few RDM files hold raw data from devices like microscopes, used in imaging and analysis.

FilExt.com note: Reviewing the file content (for example, spotting XML tags or JSON brackets) helps identify which program is needed to open it. Always use the specific software version for your file to avoid errors.

How to open an RDM file

RDM file extension format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Below you will find our evaluation of the RDM files:

As a file extension, RDM isn't very common and is used by different programs with different formats. The following file formats are most commonly found in RDM files:

• 25% of all RDM files are using the well-known JSON file format to store the data. JSON (JavaScript Object Notation) is a lightweight data−interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. RDM files are between 18 KB and 240 KB in size. The file type was developed only in the last few years. The files contain the following words: data, layers, source, __type, d_paint, Layer, Location, flash, Point, geom, alpha, locator and shadow. A usual file name is map.rdm. These files are often associated with game.
• 20% of all RDM files internally utilize the XML file format. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. The average file size is 39 KB with most files being between 1 KB and 140 KB in size. Certain words are almost always found in the files, such as <?xml version="1.0"?>, <ArrayOfConnection>, <Connection> and <ConnectionType>Group</ConnectionType>.

All other RDM files (55%) have different formats, often e.g. RDM and DQwCAA. Files like these are sometimes linked to ndry, arctic, docx, public, nsdry, nwdry or ecos. If you want to find out what your RDM file contains, drag and drop it onto this page.
