I get a warning every time I try to copy any image (JPG, PNG, screenshot, camera photo, etc.) from my Dropbox to an external NAS (NetGear ReadyNAS NV+), stating:
Are you sure you want to copy this file without its properties?
The file myphoto.jpg has properties that can't be copied to the new location.
Copying the image from Dropbox to another local folder does not produce this warning, but then later copying that image to my NAS results in the same warning.
Copying any other image from my local drive, that hasn't been in Dropbox, does not result in this warning, so it is something specific to Dropbox.
If I compare all the reported properties of the image (File > Properties > Details) then everything that is reported is OK and nothing is missing. The MD5 hash of both files is also the same.
This only seems to affect images. Text files and PDFs copy without warning.
I never got this warning with Windows XP.
So, Dropbox is adding something to the image file properties, but what?
This is a bit of an annoyance, as I'm always copying images from Dropbox to my NAS! So is there anyway to suppress, or preferably resolve, this warning?
