Building more thumbnails... how long does it take?

i have waited for 2 days…already…:confounded:

Hello,

 It depends on how many pictures you have and if the My Cloud is also doing any other type of activities, like file transfers, safepoints or remote access for example

suggest to add an option (disable creating Thumbnails)

and a estimated time for current files…

it seems to me that never reach the end… 4 days…
