When Whispa was started every file uploaded to us was zipped on upload. This was great to begin with as it saved on storage space and also made it easier to serve downloads to end users. Unfortunately it also had downsides too.
Today we released a "Send to a friend" feature on Whispa which allows you to enter a friend or colleagues contact details after upload. This will then send them an email with a link back to download the files that you have uploaded.
