Data File is a file hosting service that sells itself as being the reliable destination for putting files up on the Internet. It has a fantastic uptime and support service that will make sure any questions you have are answered in a matter of minutes. What's more, their prices are very competitive if you want to have short-term access to their downloading and uploading features.
You have the choice between 30, 60 and 90 days with the best price being offered at the 3-month period. Note that while Data File is very reliable, they do have a cap on the amount of bandwidth that you can use within the length of your account. It's a pretty high value, but I think what they're basically doing here is making this more of a personal use service as opposed to a commercially viable host. Put simply, if you're looking to share material with millions of people, look elsewhere.
The service is anonymous and they pride themselves on their safe, secure servers. Free downloading and uploading are available, but the premium service is really where it's at.
