Single File System is a library designed to provide an easy way to work with multiple files and folders stored as a part of a single file using advanced compression and encryption functionality. This solution encapsulates small yet powerful file system within a single file.
Single File System is based on new special SFS-technology, which has a number of unique features and provides the new benefits for application building.
    Key features:
  • Compression on-the–fly with flexible algorithms: from fast to maximum
  • Transparent strong encryption provided by Rijndael algorithm, the AES winner
  • Fully compatibility with standard functions operating with files and folders
  • TFileStream interface to deal with files transparently stored within a single file
  • Recovering physically damaged files
  • Progress indication for potentially slow operations
  • Huge files support: more than 4 GB even on FAT-32
  • Running applications stored in SFS file.
  • Loading DLLs stored in SFS file.
  • Self-extracting support (SFX) for SFS file.
    SFS use cases:
  • File of custom format. Typically if the application uses different data like texts, images, binary data, there should be a plenty of files for each type of data. With SFS you get a unique opportunity to store all these files as a parts of a single file with minimum changes in your application code. Additionally SFS gives you advanced compression and encryption capabilities, so you can easily decrease the size of application data and protect it from unauthorized access.
  • Archiver. SFS provides the user a simple possibility to create, manage, protect and control archive files in user application.
  • Backup software. With SFS the user gets an easy way to perform secure, hard compressed or fast backups in user application.
  • Multimedia application. SFS help you essentially decrease the hard disk space and increase convenience of work with huge number of small files such as sound or graphic files collection as well as make your application compatible with all OS if it uses huge files (> 4 GB) such as video files.
