Ok guys, so I am on a pretty slow internet connection today. I was just testing the attach field with a video upload to see if the video can be playable from inside erpnext.
I selected a video 35M large. After waiting for 20 minutes to upload, at the end I received the error, file size is too large - maximum 10M
This notice could have helped from the beginning … so, is it possible for erpnext to see the file size before clicking upload ? pfff
