If you’d like a suggestion re uploading large files, try WeTransfer.

https://www.wetransfer.com/

* This is the easiest upload site to use: zip your track or tracks, go to the site and select free version, load zip file, enter my email address and select “Transfer”. There is no cost to use the free version and the limit per transfer is 2 gigabytes and you will get a confirmation message when I have downloaded the file(s).

If using Dropbox, please make sure we are authorized to use it. If using Google drive or any other upload site please zip the files first. Some sites will display each file separately without option for us to zip so by the time one selects each file and selects download, it can take close to 1/2 hr. to download 10 large mix files.
