I m using say "file.dmp.Z" which is basically a compressed form of file "file.dmp" in SCO Unix.
In one interview I got questioned what is "file.z".
Can any one let me know the difference between *.Z & *.z in Unix file format.

I'm not sure whether SCO unix supports it ...but The pack command attempts to store the specified files in a compressed form. Wherever possible (and useful), each inputfile file is replaced by a packed file file.z with the same access modes, access and modified dates, and owner as thoseof file. If pack is successful, file will be removed.

Please check help for pack, pcat, unpack - commands
