I was looking at some of the pictures taken with my camera (Google Camera) and there are some that have :nopm: in the file name. The format of the file names are the same, just some contain this after the timestamp, before the extension.

enter image description here

When I use MTP on windows to copy them to my PC they copy fine, because it removes the : from the file name.

What is the meaning of the :nopm:?

I have added a more detailed picture that shows :nopm: does not have anything to do with if it was taken in the morning. This wouldn't make sense anyhow, as the timestamp is already in 24 hour format. 231314 = 11:13PM, there is no need for an AM/PM indicator.

    From what I can tell it is Hangouts that most normally adds the :nopm: to images. Is there a chance you sent/received those ones over Hangouts. To be totally honest it seems like an issue with Google Camera, but I've seen quite a few people point the finger at Hangouts.

  • It does look like it originates from Hangouts. From the photos, I remember taking them all while sending them to people over MMS via Hangouts. Feb 9, 2015 at 15:55
  • @RossC, if you put that as an answer, I will accept it. It does seem that Hangouts is the cause. I am still not sure what it means, but at least I know what is doing it. Feb 9, 2015 at 17:33

    Per a comment left as an answer by another user: It looks like the :nopm: prevents the new Photos app from uploading the image. Perhaps that is its purpose as you mentioned below @Ryan. Jun 3, 2015 at 14:39

This is not related to AM/PM as the screenshot shows. This issue appears to happen due to Google Hangouts. I have heard from a few Moto G owners that this happens a lot on that device, and can cause issues moving to SD card, however, it really seems to be down to Google Hangouts. Here is a mention on Reddit, and on an unrelated thread the same issue crops up.

Upon reading this issue on Github:

google hangouts produce [sic]images of this form image_timestamp.:nopm:.png

There is no easy fix at present, but I will investigate.

  • Doesn't really tell us why it does this in the first place.

  • @KenSharp I haven't forgotten this answer, I just can't get an answer from anyone at the moment. There is nothing in the code I've looked at to explain it, and no answer from Google.

    After thinking about this for some time, I actually think that :nopm: means NO Photo Manager. As it appears that the Google+ Photos app will not backup the photos that contain :nopm:. This is just a theory. Apr 7, 2015 at 14:33
  • @RyanConrad it's actually a good one. It makes sense! Then again, some of these things don't seem to make sense at the best of times! :)
