Hello, thanks for your feedback.
Please include the exact keyword "LR_180"(an underscore is needed) in the file name or folder name, then SKYBOX will automatically identify the VR format based on the keyword.
About the second issue, I'm sorry there's no way to save the thumbnails onto the USB drive. After restarting SKYBOX or re-plugging your USB drive, SKYBOX will directly display the thumbnails without having to regenerate them one by one.
What's more, you can go to SKYBOX's "Global Settings" and turn off "Show Thumbnails".
