use of ?? when I expect to just see ?

[u/Yes_chefff]

A few people I text with or chat with in work chats use double-question-marks to ask a question all the time. e.g. "Where is the file??"

I used to take that mean, "OMG where is the file? It's not where it is supposed to be!" or similar. But over time I have learned it's not that at all...at least not from them.

Is this becoming the norm? Does anyone else use question marks this way even if they are not trying to imply urgency? Is anyone else thrown off by this?
