might have been opened twice and it wouldn't allow you to save since it was open. Applications do this as a type of version control. If a spreadsheet is opened twice and you save one to people edits would be written over.
This is so strange. I had a few Excel spreadsheets open. I made some changes to them. I tried to save the changes on the first sheet, but a window opened saying the sheet couldn't be saved and that a copy was being placed in the folder that held the original sheet. I thought that would be no problem, so I clicked OK. The original sheet disappeared, and a copy was made. What the window didn't say is that the copy won't open with Excel, and it asks what other programs did I want to use to open it. None of the other programs could open it. I tried closing the second spreadsheet and got the same window. This time I was not going to click OK; instead I closed the window, and the same thing happened -- the original disappeared, and a copy was made. The copies are titled "D0180300" and "71861300." I clicked on their Properties, but that didn't show me anything about how I could open them. Fortunately, I had back-ups to both sheets, although they were a few months old. I'm asking: 1) Why did this happen and is there a way to avoid this happening in the future? 2) How can I open the copies? 3) Is there a way to dig into the computer to find those spreadsheets before they were closed? I'm using a 2014 HP Pavilion laptop with Windows 8 and Microsoft 2000. I've never seen this happen before.
