Did the progress bar complete during export or did it stall?
Are you exporting into a new folder or sub-folder? Make sure it has read & write permissions.
Exporting into the same folder. The progress bar never showed up. Where do I check permissions?
On Windows right-click on the folder and choose properties, then go to the security tab. On Mac use Cmd+i to open the info dialog.
Also check your LR export settings to ensure the file path is correct.
If the files are on an external drive make sure it is properly connected.
I will keep looking the permissions were correct and other solders allow export. this one finally did export to desktop after it sat for 5 min. maybe it needs to be turned off for a while. thank you for your help.
