What are the common places to find log files of an application in Windows 7?

I know a common place is "C:\Users\MY_USER_NAME\AppData\Local", but there are many folders with encrypted names like {73830A3D-00DD-4EC9-8905-7EACC7074E15}. I have no idea how to decrypt those.

The particular application I am interested in Keil Microvision. I googled and can't find a log location (not surprised, since it's not a software that everybody uses), so I am looking for a general way to locate the log locations.

Thanks.

"The particular application I am interested in Keil Microvision..... so I am looking for a general way to locate the log locations." What is the question? Where Keil Microvision saves its logs, or a general way to locate log locations? –  TFM Mar 14 '13 at 6:15
    
@TFM I am looking for a general way to locate an application's logs. But if someone happens to know where Keil Microvision saves it, that would be great as well. This is like "I want to know how to fish, but if someone can give me a fish so I won't starve today, I would be equally grateful." –  CodeNoob Mar 15 '13 at 4:46
    
The "problem" is, like Keltari describes in his answer, there's no common rule (at least in Windows) on where the logs should be saved. So they are saved everywhere. That's why knowing the general rule of thumb for finding logs may not help you find the Keil Microvision's logs. –  TFM Mar 15 '13 at 5:13

Log files are application dependent. There is no guarantee an application will log to the event log's application log, to a particular folder, or even do any logging at all. You need to consult your applications manual or contact support to find where it does its logging and/or how to enable it.

Most commonly, you will find an application will place its logs in its top level of its application folder. Such as "c:\program files\myapp\log.txt" or in a log folder, such as "c:\program files\myapp\logs\log.txt." Again, you need to consult the manual or contact their support for the application in question.

Files/folders with GUID names (the numbers in curly brackets) are not, in general, encrypted and you can look in them as well as any others. Applications sometimes write a log file under a folder named after themselves. Your user TEMP folder is another likely spot to look. As far as I can tell, the vast majority of applications do not keep a log file at all.

Sorry, by "encrypted" I mean encrypted names.. how do I find the GUID of an application? –  CodeNoob Mar 14 '13 at 4:13

Not sure exactly what kind of logs you are looking for, but the Windows logs related to applications can be found in the Event Viewer. Ctrl+x -> Event Viewer. Check the left hand side tree for Windows Logs/Application. These usually aren't super specific, but they may help if you can't find anything else. Ultimately it is up to the application to keep logs and some don't.
