Selling ebooks in multiple formats

Three different formats means three different files, right? Not sure if there’s any magic plugin to make that a single upload.

Only if you zip ’em all up into one file. But each download must be separatly uploaded.

Thank you Gabe and Ipstenu.
Yes the different formats refers to loading ebooks on an ecommerce platform, ready for download in various formats e.g. PDF, MOBI or ePub. I am presently having to load one book title 3 times, once in each format, and what i am asking is if there’s a way I can do this with each format available to be clicked on to download but only to have one cover picture and one book description with the 3 available options below that cover and description? At present I load the same book cover and description with eack format.
Hope this makes sense! go look here and you will see (a picture is better than a 1000 words) what I am referring to: https://www.searchandtrace.net/shop/
Thanks for the time any one devotes to helping me.

Depends on the plugin. I just upload the cover once, and link back to it three times, personally!
