Where can I find the Du Meter Log file? I tried searching C:\ProgramData\Hagel Technologies\DU Meter but the folder is empty. I also tried C:\Users\Username\AppData\Roaming and Local and LocalLow but none of them even have a Du Meter or Hagel Technologies folder. I even tried searching the temp folder but still nothing.

I have a NetMeter.csv log file that I want to try and replace over the Du Meter log file cause I can't seem to find any other way to import data into Du Meter.

Depending on the chain of upgrades, e.g. version 3.x -> 4.x -> 5.x, the database file can end up in odd places. To find it for sure, do this:

  • Open RegEdit, take a look in HKEY_LOCAL_MACHINE\SOFTWARE\Hagel\DU Meter or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Hagel\DU Meter (if you're using 64-bit Windows)

  • Note the DatabaseFile value there. It points to current DU Meter dtabase file location. By default, it is in the LocalSystem's profile, e.g. C:\Windows\system32\config\systemprofile\AppData\Local\Hagel Technologies\DU Meter\DUMeter.sqb or similar.


DU Meter's data file is SQLite database. It is held open by DU Meter service, and if you want to backup it or otherwise tinker with it (not supported at all), stop the service first. I strongly advice you to leave this file alone. If you need to backup or restore your data, use "Database Management" in DU Meter options.

Thanks for the answer, since I can import data from "Database Management" then searching for the db file doesn't matter (though I was still curious as to where it was). I didn't expect it to be in the Windows folder (seems like a strange location to me)... but great program btw. It is a lot more advanced than NetMeter that I was using previously. – Jack Nov 17 '11 at 2:36
Windows 7 x64: C:\Windows\SysWOW64\config\systemprofile\AppData\Local\Hagel Technologies – user330322 Jun 7 '14 at 15:18

Try Documents and Settings/All Users/Application Data/Hagel Technologies/DU Meter.

I'm running Windows 7, I don't have that folder. – Jack Nov 16 '11 at 21:59
%APPDATA%/Hagel Technologies/DU Meter/ – Shiki Nov 16 '11 at 22:05
@Shiki You know Windows uses \ don't you? looking at a windows path with / looks so wrong , doesn't it? – barlop Nov 16 '11 at 22:56
That's actually the same folder as C:\Users\Username\AppData\Roaming... and Hagel or Du Meter doesn't exist. – Jack Nov 16 '11 at 23:29
@barlop - I just copied from JRobert's answer, but yeah, you are right... %APPDATA%\Hagel Technologies\DU Meter\ – Shiki Nov 17 '11 at 8:44
