What I found : The IFS seems an extension of the network redirector, intended to solve some data corruption problems. It did exist in DOS 4 only and was not well documented by Microsoft. The following books offer some information: Schulman "Undocumented DOS", 1991 edition page 217 Podanoffsky "Dis

Thanks Ralf for the file, it is very interesting. I am not fully convinced that NOTHING from the IFS was ever developed in MS-DOS 4.X and later taken back in 5.0+. The network redirector appeared earlier, and I suppose that with IFS, MS tried to resolve some absent functionality in the network re
