What is an ERX file?

Other Variants:

ELF Variant: An executable file used in VxWorks systems.
EXE Variant: A Windows executable seen with Saflok ERX Importer or as an Embarcadero resource file.

ERX file format:

If you can determine the file format, the associated program can also be determined. The file format can be deduced from the file extension and the signature. 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. When there is a problem with a file, the first step to solving it is to determine the file format. Below you will find our evaluation of the ERX files:

The ERX file ending mainly uses a defined ERX format. The file formats most commonly found in ERX files are:

70% of all ERX files store the data in 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. If you open these files in a text editor, you can view and read the content yourself. The files are on average 610 KB in size and range from 47 KB to 4 MB. The file type is relatively new. The keywords <?xml version="1.0" encoding="UTF-8"?>, Alias, LastConnect, Model, Server, User, ConnectAs, Color, NORMAL, 16777215 and OracleHome are typical for these files. Files like these have the following tags: diagram, schema, erdiagram and tables.
10% of all ERX files are based on the popular Source file format. A source code is the set of instructions written by a programmer using a computer programming language like JavaScript, C++ or Basic. This code is translated into machine language by a compiler. The translated result is called app, program or executable. These files contain text and words, not binary data. The average file size is 120 KB with most files being between 33 KB and 530 KB in size. Certain words are almost always found in the files, such as (ERWIN_TEXT_ID INTEGER NOT NULL, /* PLATINUM ERwin/ERX 3.5 */, CREATE TABLE ERW_TEXT, DIAG_ID INTEGER NOT NULL and ERWIN_TEXT_VALUE VARCHAR(2. Files like these have the following tags: project.

All the rest of the ERX files (20%) have different formats, such as ZIP, ELF and EXE. Files like these are sometimes linked to master, saflok, model or user. You can get all the details of your ERX file by dragging it onto this page or by clicking the button "Choose your .erx file to view" above.

To make sure that your ERX file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
