All about R2D Files
The R2D file type is primarily associated with Reflex.
What is an R2D file
R2D files mostly belong to Reflex by Borland Software Corporation. Reflex is an old DOS flat-file database system. The size of the database was limited to the amount of system memory.
How to open an R2D file
You need a suitable software like Reflex to open an R2D file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your R2D file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a R2D file directly in the browser:. Just drag the file onto this browser window and drop it.

R2D file format:
To view or edit R2D files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the R2D files:
R2D is not a common file extension and includes various formats for various programs. However, the following two file formats are common:
- 45% of all R2D files are Reflex 2 Database files. These files contain neither text nor words, but only data. A typical file size is 98 KB. The keywords Reflex2 are typical for these files.
- 20% of all R2D files have the same signature [RISA-2D_INPUT_DATA]. 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 files are on average 29 KB in size and range from 18 KB to 51 KB. The keywords [DATA_INTEGRITY_KEY] <1>, [END_VERSION_NUMBER], [RISA-2D_INPUT_DATA], [VERSION_NUMBER] <1>, END_DATA_INTEGRITY_KEY, [END_PROGRAM_INFO] and [PROGRAM_INFO] <1> are typical for these files.
All the rest of the R2D files (35%) have different formats, often, for example, RDPE. These files sometimes refer to viewer or oceanic. You can get all the details of your R2D file by dragging it onto this page or by clicking the button "Choose your .r2d file to analyze" above.
