What is a WER file?

WER files mostly belong to Windows by Microsoft. A WER file is a Windows error report generated when kernel, driver, or application level errors occur on Windows. Such errors can range from unresponsive applications, crashed applications, driver problems, to system component bugs. After information about a crash, related processes, and some troubleshooting information are saved in a WER file, Windows Error Reporting service sends that report to Microsoft. Another type of WER file is a database schema diagram created by WinSQL database administration program for SQL Server.

How to open WER files

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

WER file format:

Every file has a defined file format, i.e. how the data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. 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 examination of the WER files comes to the following conclusion:

The WER file type includes various formats for various programs. The two most common formats are as follows:

50% of all WER files are Windows Error Report files. They consist of illegible, cryptic characters. The files are 2 KB to 19 KB in size, with a median of 12 KB. The file type was developed only in the last few years. Certain words are almost always found in the files, such as EventTime, Version=1, Consent=1, ReportType=2, EventType=APPCRASH and UploadTime. The file name Report.wer is characteristic of these files.
20% of all WER files are based on the well-known UTF-16 (LE) file format. UTF-16 (LE) is an character encoding system for Unicode. UTF-16 files can be viewed in any modern text editor. These files start with the two bytes FF FE, the so called byte order mark (BOM). These files are binary files, so they do not contain text, but only cryptic characters. Most of these files are 6 KB to 31 KB in size. The keywords Consent=1, EventTime, Version=1, ReportType=2, EventType=APPCRASH and UploadTime=13 are typical for these files. The file name Report.wer is characteristic of these files.

All other WER files (30%) have no consistent format. If you want to find out what your WER file contains, drag and drop it onto this page.
