DxO not scanning jpegs - HELp
Check that the filters are off.
Click over the folder again and wait for it to load, sometimes it takes a while for DxO to load a folder and it looks it's not doing anything.
Restart the program.
Restart your computer.
Update to V7.2.1
Pay close attention to the filter options, sometimes at a glance they seem to be deactivated but a through inspection will show there is one that blocks the reading of JPEGs.
Also, check if the JPEGs aren't too small in size. There is an option in Preferences that blocks images that are too small to process, unless DxO generated them itself.
