Thanks for the response, but I think you're missing some key details. Firstly the videos that I create are synching to the Meta app, the issue under discussion in this thread is the fact that you can't download the videos from Quest to a phone or computer. It's also not a matter of a long time, it's a matter of the downloads not functioning. Also, you didn't answer the question on how to view the file size. As I already mentioned, my phone is up to date, my quest software is up to date, the internet connection is great. The issue is not on my side. Your point about the "chance" that the files are too large to download sounds like the key issue here. I'm assuming you know what this maximum file size is, but it's so small that it's embarrassing to mention in a public forum? Because otherwise you might answer by saying "Files larger than 1 Mb cannot be downloaded from Meta Quest".
Thanks for sharing the link but it didn't help me either. I use a Mac, and the instructions ask for you to download an Android file transfer tool, which is weird, and that tool complains because I don't have an Android device. So that doesn't help either. (I note that the headline is overly optimistic by saying "There are several ways to transfer photos and videos" and then proceeds to provide one way for a PC and one way for a Mac, and the Mac way requires an Android device. Which is technically only one way for Mac users with Android and zero ways for Mac users without Android.)
I think probably what you want to say is that it's not possible? If so, blink twice and we won't tell your boss you told us.
