Question

What Object or Table in SFDC starts with and Id prefix of 0EM?

I have uploaded an image into a Knowledge__kav object in Salesforce, which is basically the knowledge article page.

And when I open the link to the image, it gives an Id starting with 0EM.

But, what table does the Id starting with 0EM relate to?

The label for the object is Other Uploaded Images and Files

Answer 1

I uploaded it into Content Version instead and referred to the url as img src.
