You may wonder what makes Swapper, and its Wambo File System faster for transferring files, and particularly media, from one computer to another. The answer is really simple: we use all the possible tricks and complex technologies to compress and accelerate your upload and download transfers. And there are quite a few.

Compression. The WFS automatically compresses, resizes every media file if the sender chooses to use the option (Photo formats supported: BMP, GIF, JPEG, PNG ,ICO, and TIFF - Video formats: MP4, RMVB, VCD, SVCD, DVD, MOV, AVI, DIVX, WMV, MP3, WMA - Audio formats: WAV, MP3).

Caching. In order to save upload bandwith and time, the WFS performs signature computations prior to compression and encryption to check if a file that’s in the process of being uploaded is already present on the WFS grid. Such signature computations, which are secure and delocalized, are compared against a global signature index maintained on the WFS central servers. This technology results in massive bandwidth savings since a given file does not need to be re-uploaded, ever.

Swarming. With the WFS, computers that have downloaded a given file automatically become sources for new recipients. The benefit of swarming is scalability (files are downloaded from multiple sources) and speed.

Pre-fetching. Pre-fetching is a well know technique for retrieving files across a network of computers which gives a sensation of speed for the user by automatically downloading a fraction of the file prior to the user actually requesting it. When a file arrives in a recipients’ Inbox with Wambo running, the WFS will automatically download fragments ahead of time without being intrusive to the end user, resulting in significant faster perceived downloads.
