How do I work with file sharing? I'm new to all this, and I'm having problems.

There are several ways to upload files to hosting. The easiest way to do this is through the hosting control panel zip-archive. You can also use a third-party FTP-client, if it is more convenient to work with it or the size of the archive exceeds the allowable size in the control panel. but to avoid problems with the lack of space, you should choose a hosting with a large size. For example, keep2share. And with a promo code for Keep2share Premium you can get 10% extra days of subscription (for example, 400 days instead of the usual 365 days)

I had the same problem with the file exchange
