Hello,
I'm not sure if this has been mentioned already, I can't find any posts on it but I was wondering why Comment, Description and UserDescription show the same information and if they can be used seperately.
I would really like to make use of all 3 in my file organization as I use the Details view extensively and I love the use of the columns. Sometimes, when looking through a folder with a large number of files, I like to sort by different columns by switching to different ones within the same folder. I have been using 'Comment' to add particular notes to my files and then 'Tag' to add one-word tags that I now like to group by. But I would really like to make use of the 'User Description' and 'Description' column, instead of them showing the same info in 'Comment'. Or maybe a new field can be created so we can add other information that won't show up in other columns. With my files I add in the comments some miscellaneous information, but the Description and User Description can have other information that is more formal and descriptive and then I can sort them by either one of those if I don't want to overload the comment data field or the tags (I make a lot of notes in my files). Could you add something like that? Or is there something like that already in Dopus that I can use instead? Thank you.
I think Comment is distinct from User Description, but only for certain filetypes (ones which support an explicit Comment field, which Opus knows about). For others, it'll display the same thing as User Description, as a fallback.
Comment is in the Document category or columns, so I would expect it to be there for Office documents and/or PDF files, or similar.
The Description column shows both the user description and automatically generated information, such as the dimensions of an image file. The User Description column exists in case you only want to see that and not the automatically generated information.
I see what you mean, yes that happens with pictures, but not with documents (.rtf, .doc, docx, .pdf) and other filetypes that are not necessarily documents (.xml, .html. etc) I am interested in coding and work with files like .xmls, htmls and .cpps quite a lot and they don't fit in the normal document category. When I add info in Comment via metadata it also appears in User Description and Description too. Is there another way of adding comments and user descriptions other than via metadata or 'Set Description' via File Commands that will show different information? Can you perhaps add extra custom/misc data fields like that for more rarely-used filetypes in a future update if its possible?
Script columns let you do this yourself, if you can come up with a way to store the data (e.g. in a specially formatted xml comment for xml, or as NTFS alternate data streams for general filetypes), if the description, tags and labels built in to Opus aren't enough.
Thats sounds like just what I want, Thank you! I bet you can guess what my next question will be lol. How do I find these script columns?
Just to add, I am only a beginner in coding 
Scripting / Example Scripts / Adding a new Column is a good place to start.
Scripting Reference is the main place to look for quick details, once you're up to speed.
Lots of examples, of varying complexity (and varying understandability ) here: Script Buttons & Add-Ins.
Thank you so much for your help. I will start reading those straightaway
