8. ESRM 250 & CFR 520: Introduction to GIS © Phil Hurvitz, 1999-2009 Be careful about renaming & copying files Every file of a multiple-file data source must be renamed/copied Files that are renamed/copied will not be “found” in map documents Files to be copied/renamed cannot be in use in current project Data sources are frequently composed of multiple individual files  Shapefiles are composed of at least 3 separate files  Image data sources are composed of at least 1 file, at most 4 8 of 26 Renaming & copying
