Solid File System™ (SolFS) - Single-File Virtual File System for .NET, Windows, Linux, PocketPC

Solid File System (SolFS) is a flexible, high-performance file system, designed for use with real media (such as Hard Drives or Flash Cards) or logical structures (files on disks, database records, application resources, and raw memory). SolFS gives you advantages of reliable encryption, transparent compression, high sorage capacity, application-defined attributes, custom tags, storage metadata, use of Unicode, creation of virtual disks, and support of mobile devices.

Solid File System™ (SolFS) - Single - File Virtual File System for Delphi and C++Builder

Solid File System (SolFS) is an implementation of file system in a single storage (physical file, database record or just memory block). It operates much like "real" file systems do, i.e. it operates with pages and keeps hierarchical directories structure inside. Page mode allows SolFS quickly and efficiently manage (create/write/delete) files and folders. At the same time SolFS is not resource-hungry - it allocates physical disk space only when it is needed and can automatically reduce file size when the space is not needed anymore.

Solid File System can be statically linked to your Delphi or C++Builder application so you don't need to carry external DLLs with your program.

If you are choosing which single-file virtual file system to choose, please see the table below:
