PicoStorage allows you to store hierarhical information (similar to "files and directories") inside a single file
PicoStorage allows you to store hierarhical information (similar to "files and directories") inside a single file. The functionality offered is largely equivalent to the one offered by any filesystem, or by the Structured Storage and Compound Files.
PicoStorage can efficiently handle huge numbers of small files, with very economical disk usage; it also allows you to keep open (in RAM) simultaneously a large number of files. Transaction support guarantees data integrity.

The library is available on a dual-license basis: under GPL for free, and under a commercial license for use in closed-source applications.
The library contains the classes File and Dir to represent files and directories. On a File you can read or write a number of bytes from a given offset, and set/get the file size. On a Dir you can create entries (either files or subdirectories), open entries, delete entries, and iterate over the directory's content.
The storage itself (i.e. the whole hierarchical structure, contained in a filesystem file) is represented by the class Storage. Using this class, you can create or open a storage, obtain the root directory of the storage, close the storage and do commit or rollback.
