Opening REX Files

The REX file type is primarily associated with Qiagen Rotor-Gene Q Series Software.

What is a REX file?

REX files mostly belong to Qiagen Rotor-Gene Q Series Software. REX files are not one‐type files. They can be used by different systems to store precise data.
For example, some of the files are PCR experiment data files. They are built in XML format and capture qPCR results from instruments such as the Rotor-Gene Q series by Qiagen. The XML structure stores experimental details in a way that specialized software can process the data directly.
In other cases, many REX files hold vehicle diagnostic data. Multiple diagnostic systems from various vendors (for example, tools linked with Volvo Tech Tool, DiagBox, Vident iLink4, or Xentry Diagnostics OpenShell) use them. Some of these files are even provided in a compressed format. Vendors often include specific markers so the dedicated diagnostic software can parse and display the results. For instance, you may find links like Volvo Trucks or Vident referenced with particular implementations.
Less common uses include:

Road design data files (AP5.0 Cabinet data files used by Bentley Rail Track).

Zipped XML files for system analysis, such as those from Raman Analyzer used with Xcalibur (Renishaw).

WordPerfect Printer Driver files for legacy systems like WordPerfect for DOS (Corel).

Each REX file must be handled with the software that created it. Examine the content (for example, look for XML tags) to decide which application to use. A plain-text editor can help reveal whether the file is XML or a compressed archive, but the proper vendor tool is usually needed to process all functions of the file correctly.

qPCR Data: XML format files storing experimental PCR results.
Vehicle Diagnostics: Files that record car diagnostic logs and related data.
Other Specialized Data: Such as road design information or printer driver setups.

How can I open a REX file?

You need a suitable software like Qiagen Rotor-Gene Q Series Software to open a REX 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 REX file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a REX file directly in the browser:. Just drag the file onto this browser window and drop it.

REXX (Script) by IBM
REXX (REstructured eXtended eXecutor) is an interpreted programming language which was developed at IBM. It is a structured high-level programming language which was designed to be both easy to learn and easy to read. Both commercial and open source interpreters for REXX are available on a wide range of computing platforms, and compilers are available for IBM mainframes. This file format is classified as Source Code. Related links: Wikipedia REXX Page

REX file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The file format can be deduced from the file extension and the signature. File extension, signature and file format must match; otherwise errors will occur when the file is opened. If there are problems opening a file, you must first determine the file format used. Our evaluation of the REX files is as follows:

The REX file ending includes various formats for various programs. But the following two file formats are common:

40% of all REX files are using the well-known XML file format to store the data. 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. The contents of these files are easily readable with a text editor. REX files are between 160 KB and 310 KB in size. This file type is based on cutting-edge technology. Several words can almost always be found in the files, e.g. <?xml version="1.0" encoding="utf-8" ?>, <Experiment>, Operator, <RexHeader>REX 3.15</RexHeader>, StartTime, <Notes></Notes>, <RunId></RunId>, <Rotor>3</Rotor> and <Rotor>2</Rotor>. Such files are related to covid, qpcr, sars and thermo.
9% of all REX files start with the bytes ÃÃÃÃ crucial for this file format. If you open these files in a text editor, you will see only illegible characters. The average file size is 450 bytes with most files being between 320 bytes and 1 KB in size. The keywords BENZ are typical for these files.

The remaining 51% of all REX files are different files with different signatures. If you want to find out what your REX file contains, drag and drop it onto this page.

How to solve problems with REX files

Associate the REX file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest REX file format. Search, therefore, e.g. on the manufacturer website after an available Qiagen Rotor-Gene Q Series Software update.
To make sure that your REX file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
