The issue of transferring and sharing large files remains, even in this day and age of high speed internet and gigabit networks. Even in work settings, the use of USB keys has dramatically increased as created files have quickly become larger than the most generous email attachment rules allow.
In comes FileDropper to the rescue! Just create a free account and upload your file (up to 5GB) and simply share the link with whoever needs the file! As stated by the creators of FileDropper, the goal of the company is to "offer the most basic file hosting service so you can share your stuff quickly. Files uploaded to FileDropper are kept as long as they are downloaded at least once in a 30 day period. If the file is inactive for 30 days consecutively, it gets deleted (of course, it is possible to get a premium FileDropper account, with the benefit that files are kept permanently!)
Brilliant service, well worth checking out!
