How can I get this information
I accepted a new church job as secretary and was given a CDR disk with limited information No one seemed to know what was on the disk, so I took a chance and installed it. No problem, as there were 4 or 5 entries. Two were ok and I could print them, but the others stated I could not open these files. We do not know who made the files but one apparently was a spread sheet. It also indicated --.XIR???? It is not critical, but is there anyway I can open them without damaging my computer. These were done in either 2007 or 2008. Any ideas???
