File Extension ERR

The file extension ERR is defined as an error log file which helps software developers and programmers to identify performance problems with a specific software application. The errors can indicate problems with the installation process, executing tasks, issues with closing out of the software application, clicking on software attributes, and other activities which are necessary for the proper functioning of a software program.

The file extension ERR is categorized as a text file type which stores error logs that result from the testing and profiling of software applications during the process of development. When software developers build software applications, the software is tested during different phases of development. This process is known as beta testing and assists developers with the identification of bugs and errors so a fix can be developed to improve software performance.

Most software applications use a standard out and standard err process when being run and developers will modify this process to identify errors during testing. Instead of using a standard output such as log.out, the developer will modify the process by using the file extension ERR such as log.ERR to log the error output. Each time the software application is run, ERR files are saved as opposed to being overwritten to monitor the error historys wi over multiple runs.

How to Open ERR Files

Since ERR files can be opened using multiple programs and applications, double click on the file to see if it will automatically open in a default program you have installed on your PC. ERR files can consist of a common plain text ASCII format, so you may already have a program which will open the file.

If you are using the Windows operating system, the file extension ERR can be opened using Microsoft Visual FoxPro 9.0, which is a development application used to build and manage software applications and components. VisualFoxPro 9.0 is available for download on the Visual FoxPro Developer Center website and is designed for use with Windows XP or later, Windows 2000 with Service Pack 3 or later, or Windows Server 2003 or later.

Windows users can also opt to use Microsoft Visual Studio 2012 Professional, which is a development application used to build desktop, web, and enterprise software applications. Visual Studio Professional 2012 is available as a free trial on the Microsoft website and is designed for Windows XP and later with .NET Framework 4.5 Advanced Services.

Since the file extension ERR is a text file type, you can open and edit the file using any text editing program. If you are using the Windows operating system, you can open ERR files with WordPad, Notepad, PSPad, TextPad, Geany, Open Office Write, or Microsoft Word.

For Mac OS X, ERR files can be opened using Apple TextEdit, AbiSource AbiWord, MacroMates TextMate, OpenOffice Write, BareBones Software BBEdit, Bean OS X, or MacVim.

If you are using the Linux operating system, you can use BSD Vi, AbiSource AbiWord, gEdit, GNU Emacs, Leafpad, Pico, OpenOffice Write, Nano Editor, or Vim to open and view the contents of the file extension ERR.
