I use it all the time!

Quite handy

I found this app to be quite useful. It acts as a file store that will hold any file, not just those that can normally be transferred via iTunes. It previews most file types, allowing documents to be read in full, images displayed, and audio played. It gives the option to open files in the appropriate app as well assuming an app is available. It can even send files via email.

I really don't understand the low scores given by many people, but they either didn't read the description of the app before installing it, or didn't bother to read the very simple instructions that are included as a document within the file list inside the app. Honestly people, learn to RTFM before claiming something doesn't work.

If the app was password protected or was able to lock files or folders with a password I would be extra happy with it. Using this on an iPad, the advertising, while large, doesn't get in the way of things. After all, this is a free file storage app, not an editing app, so screen real estate isn't at a premium.

Terrible con

Not a flash drive. Have to download app and pay for it. No info on app. No information on paying for app. The app doesn’t work like a normal app
