The feature I like best about Droplr is the simple ability to transfer a file, from one computer to the next, via the cloud by dragging and dropping a file or folder on the Droplr icon. I don't have to specify a location, name, or wait for it to upload, like I was doing prior by sending emails with attachments to myself, with Droplr, that all happens in the background without my intervention.
I dislike not being able to download files directly from the Droplr desktop app. Instead, I am directed to the Droplr website, where I can download the files. It would save me time by being able to download files directly from the desktop app. The Window desktop app hotkey control panel would benefit from a make-over. My multiple attempts to use it have often yielded no results.
Droplr advertises their collaboration tools most frequently, and I have used most of them to certain degrees. However, I find their best feature to be the way that it allows me to send files from one computer to another on my own terms, managing the logistics without impacting productivity.
My problem was file management between computers. My previous solution was using email to send myself file attachments, which I could then download from any computer. Using email was slow, hard to keep track of, and used up too much of my email providers inbox storage. Droplr helped me to resolve most of these problems.
