SmartVersion is a tool for storing multiple versions of your files inside SmartVersion Files (SVF files). You may then send these SVF files to your end-users. Your end-users can use SmartVersion to extract the version they desire from the SVF files and update their product. You may also customize exactly which versions are delivered to your end-users. SmartVersion uses intelligent compression and file comparison algorithms. Only the changes between the different product versions are stored in the SVF files. This eliminates redundant data in your SVF files and makes sure the patches you create for new versions of your products are as small as possible. For some file's types (such as text file, HTML files, Word Processing files...), it takes a significant smaller disk space than compressing each version individually. SmartVersion, unlike other patching schemes, is not limited to working with software products, or providing single version upgrades. SmartVersion is a shareware from Gilles Vollant, the creator of WinImage
