What is an RRA file?

RRA files mostly belong to RRDtool / WinRAR. Your RRA file may belong to different categories based on its internal structure. The most common use is as a Round-Robin Archive, which is a data storage method used to hold time-series data. This format typically uses a Microsoft Compound structure and is often associated with RRDtool.
Other uses include:

Windows Executable: Some RRA files are built as executable programs that run directly in Windows.

WinRAR Archive: A number of RRA files work as archive volumes similar to those created by WinRAR. For more details, visit the WinRAR webpage.

Red Alert Audio File: A few RRA files hold audio information using the RIFF format. These are used in contexts like game audio, as seen with Red Alert or Sony PlayStation systems. Further info can be found on the Command & Conquer Wiki.

FilExt.com tip: Choosing the correct application is key. For instance, use RRDtool for round-robin archives, run executable files directly in Windows, open archive volumes with WinRAR, or use a media player that supports RIFF if it’s an audio file.

How to open RRA files

RRA file format:

If you know the file format, you can also find out how to open or edit the file. The file format can be deduced from the file extension and the signature. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the RRA files produces the following result:

The RRA file extension is rarely used and includes different formats for the applicable programs. The file formats most commonly found in RRA files are:

• 30% of all RRA files use the Microsoft Compound File format, also known as Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. Compound document files are used to structure the contents of a document in the file. It is possible to divide the data into several streams, and to store these streams in different places in the file. In this way compound document files support a complete file system inside the file, the streams are like files in a real file system, and the sections are like subdirectories. The first 8 bytes of the CFB format are D0CF11E0A1B11AE1 (which looks like "DOCFILE"). If you open these files in a text editor, you will see only illegible characters. RRA files are between 65 KB and 180 KB in size. The file type was created recently.
• 15% of all RRA files internally utilize the EXE file format. EXE is the abbreviation for executable and is the standard executable file format on Windows. The format can be identified by the letters "MZ" at the beginning. Executable files can also be used to distribute viruses and other types of malicious software (malware). The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are on average 260 KB in size and range from 40 KB to 850 KB. Certain words are almost always found in the files, such as !This program cannot be run in DOS mode.

All the rest of the RRA files (55%) have different formats, often e.g. RAR and RIFF. These files are often connected to ispr, pass or wpna. If you want to find out what your RRA file contains, drag and drop it onto this page.
