What is an RX file?

RX files mostly belong to Agilent OpenLAB CDS ChemStation Edition.

Main use: RX files are used to store data from Shimadzu high-performance liquid chromatography (HPLC) experiments. They use an internal ZIP archive structure that bundles multiple data elements such as sample readings, calibration records, and instrument results.
These files also serve as containers for mass spectrometry data, allowing labs to handle experimental results in a compact, organized format.

To properly open and view an RX file, you should use dedicated analysis software. For example, Agilent OpenLAB CDS ChemStation Edition is designed to interpret these files. In many cases, renaming the file extension to .zip allows advanced users to explore the raw contents.
For more information, visit the Agilent website.

• Data Storage: Combines instrument readings, meta-data, and calibration info.
• Compression: Uses ZIP format for efficient and organized data storage.
• Usage: Supports both HPLC and mass spectrometry experiments.

FilExt.com tip: This specialized file format is essential for labs needing precise data capture and analysis from instruments.

RX file extension format:

The file format determines how the data is stored 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 RX files:

The RX file extension is rarely used and includes different formats for different programs. The two most popular formats are as follows:

• 40% of all RX files are based on the zip format, that is, an RX file includes multiple compressed files. Such a ZIP file contains 3 to 5 files. File names inside are always [Content_Types].xml, \Base\AuditTrail and \Base\InjectionACAML. Tip: If you rename the file ending to .zip and then double-click it, you see the included files and images. The files are on average 8 KB in size and range from 3 KB to 23 KB. Several words can almost always be found in the files, e.g. <?xml version="1.0" encoding="utf-8"?><Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types"><Overr and [Content_Types].xml. The file name 2020-06-01 10-30-08-00-01.rx is typical for these files. These files can be linked to solution and standard.
• 15% of all RX files internally utilize the RAR file format. RAR is a proprietary archive file format that supports data compression, error correction and file spanning. These files are binary files, so they do not contain text, but only cryptic characters. The files are 62 MB to 100 MB in size, with a median of 70 MB. The following keywords are characteristic: Rar!.

All other RX files (45%) have different formats, such as PDF. The category is ldbssd. Just click the "Choose your .rx file to analyze" button on this page to find out what your RX file is.
