Check the below link: (Some of the images having longer name)
Browse to the app (qvf file) you want to import and click Open.
If the app includes an image with a long file name, so that the full path to the image is longer than 260 characters, the import will fail. Reduce the image file name if the path is too long.
Yep I renamed with only 3 Character like "CEM.qvf" instead of "02.CEM Communications.qvf".
Please have the app link below to try by yourself:
