Considering possibilities of software of type DriveSpace, it is necessary to mark, that many users call in question dependability of storage of the compressed information. Partly their doubts have been quite justified until recently and even are fair. Really, it was possible to talk about what dependability of data storage, if in articles and books only ten years' prescription recommended to instal computers on the massive underplate. For this purpose suggested to use metal or marble slabs, a heavy table-top, etc. It preserved hard disks of computers against external vibrations and inadvertent pushes that promoted them more to a safe operation. In addition to it was mandatory to end operation on the computer initialization of commands of a parking of heads of the hard disks providing their safe arresting. Perhaps, and today to these guidelines it is necessary to listen that who works till now on computers of an out-of-date complete set in which structure hard disks in size of all in some honeycombs of megabytes use, and sometimes and tens megabytes. It is a lot of such rather low-productive systems at offices commercial and state-owned firms, higher educational institutions, schools, kindergartens, etc .

However processing techniques and the architectural solutions underlying functioning of arrangements of an information storage, did not stand on a place. Used hardware-software resources of rise of dependability, such as the newest resources of nonjammable coding, processing technique S.M.A.R.T. And others, have substantially removed a problem sharpness. They have made more attractive resources of compression of the computer information of type DriveSpace. Besides, both system and applications have some built in ways of protection and provide rather high dependability of data storage in subsystems of hard disks.

Nevertheless, recognising all advantages of the specified software of type DriveSpace, the Agent of compression, it is necessary to recognise, that users receive the greatest comfort of operation and really high dependability of data storage to the full, working in the environment of high-powered operating systems of type of Windows NT and Windows 2000. In this case there is a possibility to use the built in resources of compression of the information of these OS grounded on application of file system NTFS.

In the environment of operating systems of Windows NT and Windows 2000 will be devoted a subject of compression of the information  the following part of article. In this part features of customisation of procedures of dynamic file compression will be in detail considered.
