I also have had trouble locating the file. The mod description says it is in the storage folder, but i could not find it in %appdata%\Roaming\SpaceEngineers\Storage nor in the storage folder for my save game.

i tried looking at the source code for the mod, and i do see some code in ".bak" files that seems to be about saving a config file, but I don't know C# or SE modding really to say where it's supposed to store those files or why it might not be working.

I wanted to edit the file to reduce the power production to that of a small ship solar panel for a hard survival game.

Should be in there... sbc file

I haven't found it. i thought maybe it was the sandbox.sbc after you mentinoed that, but i didn't see any reference to power levels in that one for the treadmill. Where specifically is the file supposed to be, and under what filename?

Ctrl + F for
appdata
in that file if you can, as it's using your Computer's Designated Directory for the location, which is what
%appdata%\
is, your Operating System sets this per User on Windows (unsure about iOS and UNIX). Something, somewhere, needs to set up the Save Location, otherwise it has no idea how to retrieve extra Content (eg. Models, Textures, Scripts, etc.)

searching C:\Users\Mumberthrax\AppData\Roaming\SpaceEngineers for "ConfigData.xml" (specified in 1138636179.sbm/Data/Scripts/Treadmill/ConfigDataStore.cs.bak ) returns one result, which is from the needs mod - it has nothing in it which indicates relation to the treadmill.

searching C:\Program Files (x86)\Steam\steamapps\workshop for the same filename returns no results.

It's been a while since I looked at this and I'm a little bit better at reading code now but still not familiar with c# - but i think the commented lines in 1138636179.sbm/Data/Scripts/Treadmill/Treadmill.cs here are the reason the file is not being written to the hard drive:

public override void Init(MyObjectBuilder_EntityBase objectBuilder)
{

if (!loaded)
{
//mConfigDataStore.Load();
//mConfigDataStore.Save();
loaded=true;
}



//fastupdate = mConfigDataStore.get_FAST_UPDATE();
//maxOutput = mConfigDataStore.get_TREADMILL_POWER();

If I am reading this correctly, the functions for saving, loading, and accessing variables from the config file are not being used.
There also is an error logging line that is commented out in ConfigDataStore.cs.bak:

public void Save()
{
try
{
TextWriter writer = MyAPIGateway.Utilities.WriteFileInLocalStorage(mFilename, typeof(ConfigData));
writer.Write(MyAPIGateway.Utilities.SerializeToXML<ConfigData>(mConfigData));
writer.Flush();
writer.Close();
} catch (Exception e)
{
//MyAPIGateway.Utilities.ShowMessage("ERROR", "Error: " + e.Message + "\n" + e.StackTrace);
}

but since this save method is never called because the call is commented out in treadmill.cs, any errors which might otherwise arise are never thrown anyway.

I just realized, the OP was checking their Dedicated Server Folder.


Also, for clarification purposes of any passerby readers, it should be noted that the default Path (at least on Windows OS) for
is equal to
or
so searching
should return
which means you want
or
to properly locate your files, or more specifically
or

If you really wanna shorten the Address, you'll want something like this:
or

The reason why all of that is important is because now you know what I mean when I say your Log File located in
mentions on line 161 & 162 (roughly):
or
depending on your Operating System & Hardware. Shortened the Address will look like this:
&
Respectively. The way I get the shortened name is I'm looking it up in Command Prompt (cmd.exe) using the command, with the Flag (option).

The Reason why that location is important is because it might have more clues for you to sniff around for. It's at least worth checking out.

also, good eye on the commented out lines

looks like I uploaded a test version. derp
