This project presents the Intermediate FTP-server (IFTP), which provides the FTP-based access to the structured network file hierarchy. The IFTP-server makes a correspondence for the dispersed files from the network and convenient virtual tree-like hierarchy. It allows the user to work with the files, actually placed on different FTP-servers, as they would be placed in the content of the only one FTP-server. One of the most considerable features of the IFTP-service is the direction of the traffic - any file is transmitted directly from the containing file remote FTP-server to the user, omitting the IFTP-server, which only gives the commands through the control connection.

The library is designed for the co-working with different type indexers. Together they provides the powerful tool for data structuring of local networks.

The design of the library is based on the SWITCH-technology. It provides the separation of the program functionality from the controlling logic, localizing the last in the numbers of automata. It helps to avoid a large number of the problems connected with the unpredictable server's states.

The program is designed for the Windows NT systems. The IFTP-server is a dynamic link library (DLL), created with the help of COM and ATL technologies and C++ programming language. The demonstration program is also included.
