The Motif and OPEN LOOK versions work across networks. The Filtrix floating license is the Elan License Manager. One machine is the license server and other machines on the network are the license clients. The clients can check out a license from the server automatically, as long as there is a license available. The only difference is the way DOS handles graphics.
Supported formats are a bit different.
These utilities are Swap and Dump and the associated tools that go with them for customizing your conversions. Filtrix-DOS also includes conversions for the MagnaType and Bestinfo typesetting formats. The UNIX version does not support MagnaType or Bestinfo. Filtrix-Linux is currently available for command line use only. Filtrix for UNIX requires less than 15 megabytes for the initial installation, but can usually be trimmed down to a few megabytes by removing modules you won't be using, if you are doing only a few types of conversions.
