Managing "speed/compression degree" correlation

     FOLDER.SYS driver allows to control the speed of data compressing/
decompressing processes by changing the compression ratio via the
non-obligatory /S parameter in the CONFIG-file line relating to FOLDER.SYS
driver. Its syntax:

     /S=number

     The number can vary from 1 to 3.  Number 3 assures the fastest
compression/decompression procedures but the lowest compression ratio.
Number 1 corresponds to the slowest driver operation which in this case
achieves the highest data compression ratio. Number 2 assures the
intermediate mode of the driver operation:

     DEVICEHIGH=c:\FOLDER\FOLDER.SYS D: E: A: /S=2

     By default, the parameter value is 1.
