Like the topic says, the UDF folder does not show in the file tree. And I have failed to find a way to make it show, despite way to much time spent googling and checking every menu I can find in the program.

So I have no way of using my UDF's in the current project.

I am running logosoft V7.0.30 in a brand new VirtualBox win7 Virtual machine.

There is some issue with the installer when trying to install on Win 10, thats why I'm running it from a Vm. But it has worked perfectly except for the UDF folder not showing. Which might be unrelated.

I've attached a picture showing the file tree.

Does anyone have any idea on what might be the issue?

Yes did.

But that didn't make any difference as the UDF folder still doesn't show up in the file tree with the functions and instructions.

The one from my first picture.

You're right. I didn't even look for the data log folder.

You're almost right, no logo but not OBA7, OBA4. 

I'm reusing an old one I got for free.

Ok, that explains it.

I have almost never used a logo before. I'm much more familiar with the S7 300/400 and 1200/1500 series.

This is a small side project where I'm reusing old previously removed equipment. But I do know this particular LOGO! was installed and running a fuel oil pumping station as late as 4-5 years ago. So I didn't think it was that old.
