Open EVT File

The EVT format file is a file created by Windows Event Viewer, a program that logs system events.

In this case, the EVT contains a series of log messages that contain an ID and a series of insert strings.

The EVT is in proprietary binary format, and is used to review, analyze, and debug system performance.

To view EVT files, a computer needs to have the DLL files of the program that generated the log events.

In case the DLLs are not installed, the following error is displayed:

'Could not find description for event ID ...'.

It is important to know that EVT files can be opened without the need for DLLs, but it is not recommended.

Starting with Windows 7, EVTX files are used to replace the EVT extension.

However, Windows Event Viewer can open both types of files.
