Dataset file types in UBC's Abacus

  • .dbf: Database file.
    • The DBF file type is primarily associated with 'Database'. Started as dBASE II then proceeded through versions III, III+, and IV. Most of these files can usually be opened in Excel or Access. Often now called xBASE. The database index has the extension .NDX. (http://filext.com/file-extension/dbf)
    • The .dbf extension can refer to a number of versions of the Database format. See PRONOM: http://www.nationalarchives.gov.uk/PRONOM/Format/proFormatSearch.aspx?status=listReport.
    • MIXED (Migration to Intermediate XML for Electronic Data) can convert Dbase III and IV files to SIARD format, a software-independent XML format for long-term preservation.
  • .por: IBM SPSS Portable Data File.
  • .sav: IBM SPSS Statistics format.
    • PRONOM has no entry for .sav.
