TransFast is a data transfer solution for unprecendented download speed. TransFast provides an alternative to transferring entire files by enabling the transfer of smaller files that encapsulate the differences between old and updated versions of all file types.The software is comprised of two components: Delta Builder (Compress) usually runs where the new updated file/folder is created, and Restore (Decompress) - usually runs on the client side after receiving the Delta File/Folder. The TransFast Delta Builder compares differences between an old file and its newer version, and builds a delta file containing the differential data. The TransFast Restore seamlessly combines the old file with the delta file to create a new file for the end-user. The complete building and restoring process is fully transparent to the end-user. TransFast is capable of performing the Delta Builder and Restore with any type of file including: executable, textual, data, source, or graphic files.
