.dat is used by a myriad of program to indicate it holds some form of data for the program: .dat(a) among the heavy users is SPSS and its friends... bad part is that more then one kind of program uses it, and i've even seen perl modules relying on a .dat file for them, so there's no way to exclusively tell you where that file belongs to. On a side note, should i be adressing this mail to Kevin or Sally? regards, Jos Boumans Kevin Williams wrote: > Does anybody know what type a file with a .dat extension is? > > I've come across them as backup files, but have found one in a perl script > and I'm fairly sure it's not a back up file.
