Limiting the File Size or Type of Attachments

Cat_Boyes

We use Enterprise 10.8.1 and I am looking for a way to restrict both the file size and type (if possible) of attachments users can add to a feature class. 

This relates to a number of different datasets, so I'm looking for solutions in both Field Maps and/or Desktop Apps as users would be adding attachments in many different ways.

For file size has anyone tried this approach? https://mediaspace.esri.com/media/t/1_0u5bq2e0

Does anyone know any options for restrict file type to only .jpg for example?

I was curious on trying this and I can confirm that the file size restriction works. However, the video is very misleading. It's misleading because:

1. The example code used in the video uses the Shape_Length column of the spatial table which makes no sense. It needs to be using the DATA_SIZE column of the attachment table.
2. The attribute rule needs to be a constraint and not a calculation. While the subtitles of the video state this, the video itself does not click the constraint tab. It shows them creating an attribute rule under the calculation tab.

Otherwise, I was able to get the restriction based on file size to work.

Yes, you can also restrict based on file type just like you do for file size.

if ($feature.CONTENT_TYPE == 'image/jpeg') return true;
return false;

 You can either make separate attribute rules for file size and file type, or you can combine it into a single rule like below.

return $feature.DATA_SIZE <= 5 && $feature.CONTENT_TYPE == 'image/jpeg';
