In Abinitio, we have Multifile System. Multifiles are like different partitions of an original file. For example, if we take a 4 way partition file, which implies, data of an original file is stored in 4 different locations. So, now Control File means, which has the partition files information.Eg: /aidevfs/mfsctl/mfs0/source/sspuliv > cat .abcd.dat.mfctl (object mfile_c_type (path "file:OBSOLETE") (fs "file://[domain]/aidevfs/mfsctl/mfs0") (local_paths 4 "file://[domain]/aidevfs/mfsparts/mfs0part000/source/sspuliv/abcd.dat" "file://[domain]/aidevfs/mfsparts/mfs0part001/source/sspuliv/abcd.dat" "file://[domain]/aidevfs/mfsparts/mfs0part002/source/sspuliv/abcd.dat" "file://[domain]/aidevfs/mfsparts/mfs0part003/source/sspuliv/abcd.dat"))
