Delete SystemImage ETL Files
The first and most important reason the most common is the lack of a suitable application that supports ETL among those that are installed on your computer. A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done — the software supporting the ETL file can be found below.
Using Network Monitor to View ETL Files
However, depending on the type of ETL file, Event Viewer may not decode the event payload data and may not report event specific fields. Microsoft Message Analyzer does a better job at decoding event data. Decoding Issues It is important to note that when decoding an ETL on a system that is not the source system, information needed to properly decode event data might not be available.
When an event provider is registered on a system, it also registers information needed to decode the event data. If the event provider is not registered on the system you are using to decode an ETL file, the tool will not be able to properly parse the events.
When an event trace session is configured, how the data is logged is also configured. The old events that were overwritten are not recoverable. The WiFi. For example, Outlook when debug settings have been configured will write events to a log file when Outlook is closed.
Interesting Logs and Events The artifacts listed here just barely scratch the surface of what is stored within ETL files. Note that some logs mentioned in this section are not always present. Interesting events worth noting: Determine Activity of a Malicious Tool during Boot In this scenario we have a suspicious piece of software and we need to determine what information the trace session captured at the time the system was booted.
The source system that the ETL file was collected from was a virtual machine running Windows 10 where a known virus was purposefully executed. Not long after execution of the virus, the system was booted and the BootCKCL file was collected for analysis.
Using ETL Viewer, we can search for references to the executable. In Figure 1: Search results containing TuvtEkxir, we can see there are multiple types of events related to our executable. Figure 1: Figure 2: In Figure 3: Figure 3: In Figure 4: Disk reads by virus, we can gather what file was being read, the offset, and the size of the read.
Figure 4: Disk reads by virus Disk reads can be used to find out what section of the DLL or file was being read. Determine Information about an attached external device In this scenario, we will determine information about a WD My Passport drive that was connected to a Windows server using the energy-ntkl.
In Figure 5: Here we can gather the disk number, sector, track, cylinder and manufacturer information. Figure 5: Here we can correlate the disk number, pull size information, drive letter, and free clusters.
Figure 6: In Figure 7: PNP Information, we can correlate the friendly name to the manufacturer listed in Figure 5: WD drive Physical Disk Information. We now have the registry key for this device, which also contains the serial number, vid, and the pid. The correlation can be tricky in scenarios where there are multiple entries with the same friendly name.
Figure 7: It is located in C: There can be a large variety of events including ones that contain information related to ShellItems, network shares, applications requiring elevated privileges, and RunKey information. In Figure 8: Note that the timestamp does not indicated when it was accessed. Instead it indicates the time the trace session recorded the events.
Figure 8: Voice searches using Cortana have been observed in this ETL. In the example below I had conducted two voice searches. Caveats The timestamp field for event records does not necessarily indicate the time that an event occurred. Further research is needed to understand what the timestamp represents. The timestamp instead indicates that this information was captured by the session at the time the trace was created. ETL files can be volatile. Their volatility depends on how trace logging is configured for each session.
Tools that parse ETL files may not parse all the data including Microsoft specific tools. This is because the information needed to decode events are not always stored within the ETL file.

Malware files can be camouflaged with the same file names as legitimate files. The etl file is associated with malware only if found in the locations listed above. You can check if etl is associated with the malware listed above by running a Exterminate It! Free Scan. You can easily remove all the files listed above with Exterminate It! Disrupting the normal functioning of the operating system or rendering it completely useless.

Solved: Hi, one of my users said they are low on disk space and while searching her HD, I noticed in the Windows – Temp – McAfeeLogs folder. etl. Windows Vista, Windows Server , Windows 7, Windows 8 specific The etl file is associated with malware only if found in the locations. Microsoft told me it can happen when you use a 32Bit WPT instead of a 64Bit WPT on a 64Bit Windows. A normal ETL trace opens fine under Windows 7.
