SD Expreme Pro XMP files? What are they?

Hi,

Newbie here. I deleted all the pictures off of my sandisk Extreme Pro card using my Canon 6D. When I attempt to upload new pictures to HD, I see XMP (2KB) files for both JPG and CR2 files previously deleted. What are they and why didn't my camera delete them? Can I simply delete from desktop?

I searched internet for explanation and didn't find one.

Strange.

Thank you.

Residual stuff from Adobe products.

On the subject of deleting them, see https://photo.stackexc​hange.com …fter-creating-jpegs/88939. Perhaps best to retain them, since it seems they are unique to an image and its setting with an Adobe product.

It's information about changes you made to your images using Lightroom / Bridge / etc - metadata. If you don't move these files any changes you made to your images are lost unless you export / save as.

Generally it's best to copy your images to your computer, into a sensible folder structure, before editing. Computer disks are faster than memory cards. Any files your image software creates in the folders should be left alone unless you fully understand what they're for.

“Tim” brings up a good point in that an operation that writes to the card, should not be done by the PC. Some people feel it isn’t even recommended to format the card in the PC. Although the evidence is anecdotal, some people feel it isn’t a good idea to delete images while a card is in a card reader or PC slot. Some people have reported card issues like loss of some or all images, and often they were involved with a deletion operation. Having said that, it often is difficult to reconstruct what someone did so better to play safe.

I personally only do camera to PC image transfer by a direct cable connection. That is controversial, many feel use of a reader is fine. Once I’m a 100% satisfied the images are on the PC and a backup is made, then I disconnect the camera and do an “in camera” low level format.

Hi John from PA,

thank you. I'll do that as well. Given it takes so long to upload from card to HD, I'm not interested in uploading files I don't need.

As ever, thank you.

Hi Tim,

Thank you for the tip. I'll keep that in mind if / when I move picture files around.


Thank you.

The very first time I tried to view my pictures, we in Adobe lightroom while they were still on my card. I suspect the XMP files were written then. My computer came to a halt until I learned I was required to upload to HD first.

I'll delete these because I've already deleted the JPG and RAW files from the card. I really didn't make any edits in lightroom worth saving. In fact, I moved over to Canon DPP instead. This information that you shared is important however.

As ever, thank you for your thoughtful post.
