Install like any other local addon. (Tip: In 4.2 you can just click and drag the .zip onto blender and it'll just work)

Do turn on internet access in Blender to make sure the uploads work!

This has been tested on Windows and Mac and works perfectly. Linux is programmed to work as well but hasn't been tested by me. Created in Blender 4.2

Right out of the box there are just 3 1) You cannot upload files larger than 2 GB 2) You are limited to uploading 4 GB per hour at a time 3) Files will be deleted after download or after 14 days (whichever comes first) (so send to yourself or a friend/client)

This is basically an integrated bridge to https://file.io it will let you send your .blend file, images including renders (as png), and text files with a single button click
