So I just checked my onedrive and while I don't have any DNGs/PSDs over 100mb I do have some TIFFs over 100M and they don't show a preview. Thanks so much! I have pretty good computer skills, but still trying to fully understand LR - especially in this case! Thanks/charlene I would like to point to the onedrive folder instead of that one on my HD. I have them all in a temporary folder with the same name as that which is in my C: drive folder. I have already uploaded all of my photos from LR 'pictures' folder (that I still had on there mid 2014-2016) about 16K pics. So I thought - if I use onedrive to store my photos from my LR and direct it to read from the onedrive, I should be able to see at least my dng files.

jpegs are fine of course as they are small files. When I upload a DNG file OR a psd file that is over 100MB I cannot preview the file! I am still in the process of waiting for the engineering team to answer why I can read the file if it's under 100 MB (meaning the technology is there) and why I cannot for anything larger. Now I am in a hurry and trying to get everything on my computer uploaded in case my computer HD fails (it did last December!). I had been in the process of uploading files to cloud, but it was slow - and I was doing a little at a time. I have always had two ext HD's as backups and both of them broke down in the same WEEK! One I dropped the other not sure yet why. I have just started to upload all of my photos to onedrive.

I am reading this thread for the first time and I have some questions.
