No it doesn’t. I am in the process of trying to figure this out now. All your code does is create an event log named “yusufozturk”. if you look in the “C:\Windows\System32\winevt\Logs” folder you will notice a log file called “yusufozturk.evtx”. A folder holds a collection of logs. A folder is similar to what Microsoft has under the “Application and Services Logs”. Which it should be stated that the “Application and Services Logs” is the default location for all newly made logs. For instance Lets say we want to store something under a Folder called MyLogs. First rule is that a folder name can’t contain spaces, or not that I have seen so far. Then let’s say you want to save your “yusufozturk” log in the MyLogs directory. So your directory structure will be:

“Application and Services Logs”->”MyLogs”->”yusufozturk”

When it saves the log to the system in the “C:\Windows\System32\winevt\Logs” folder it will save the file like this MyLogs%4yusufozturk.evtx.

When creating a log under a folder it saves the file with a “-” as a separator for the multiple directories. As you add to the directory structure like:

“Application and Services Logs”->”MyLogs”->”Applications”->”yusufozturk”

The new log gets saved as: MyLogs-Applications%4yusufozturk.evtx

As you can see once you get into a Subdirectory of the primary directory the file gets saved with a hyphen separating the 2 directories.

I yet have an answer to how Microsoft, Cisco, and HP figured out how to add actual subdirectories, but soon as I figure it out I will post it all over the web. I have already tried using C#, now I am looking up methods in PowerShell.

Unfortunately there are too many people on the web that don’t have a clue on how Event Logs work and give the exact same answer as you did for how to create a folder under the “Application and Services Logs”.

Hi Mike,

You can use same C# code in PowerShell. You don’t have to look native commandlets for that. Thanks for the clarification btw. These are quick notes, especially for myself to find it quick next time when I need. So I share them in my own way. But everybody can use my scripts in their own way.

Thanks for sharing your experience.

Hello,
please send me a simple sample for this task
“Application and Services Logs”->”MyLogs”->”Applications”->”yusufozturk”
into a Subdirectory of the primary directory
