Can't find recent photographs and videos on my MacBook Pro

Dear Alvin

Thank you for responding to my problem.  I am UK based, there is a time difference between here and the US, hence the delay in getting back to you – I was fast asleep!

This is my situation.

I am a personal plus dropbox user

I have 2TB of storage.  I have used 70.1% of that storage (1.4TB).

I take my videos and photos on my Ipad and Samsung Galaxy phone and immediately upload them to dropbox where they appear very quickly. 

I have lots and lots of files and folders on my desktop – most containing many photographs used for illustrative purposes.  These take up a lot of memory/storage so I have not synched many desktop files to Dropbox as my photos and videos are already taking up most of the space.  I usually have Sync on pause so that my desktop files do not upload to Dropbox.

Up til now my photos and videos have displayed perfectly on Dropbox on my three devices – a MacBook Pro Lap Top, a Samsung Galaxy phone, and my Ipad.  The photos and videos go back to 2011.  They are still appearing OK on the Ipad dropbox, and on my phone. (Additionally I also have  Google Photos and Photos on my Ipad – they store any films or photos taken on the Ipad.)

The problem lies with the MacBook Pro dropbox.

(1) only the last three months of videos and photos are showing. 

(2) If I try to open any other photos or videos it says Zero Bytes and will not open.  I have not deleted any photos or videos so cannot understand why anything older than 3 months is showing as Zero Bytes.

I will take some photos and download them for you. 

1. Zero Bytes – worrying! – I cannot open these photos.

(2) Camera Uploads

(3) The dropbox is displaying the last three months worth of photos and movies but strangely recent ones (yesterday) are appearing as 2010 and 2009 – it does not make sense.

(4) Sync Pause

What do I need to do to restore my photos and videos? 

Thanks
