To whom it may concern Today I opened my calc spreadsheet on my USB (which I do weekly) and after inputting 4 bits of information into 4 boxes I got an error message pop up which I closed to then get another pop up and then closed the spreadsheet and now the spreadsheet won't open. When I double click on the selected document I now get a message box with a great big list saying in the top left corner next to your icon Filter Selection, I have tried the 2 options that are open office.org XML 1.0 spreadsheet and I get 2 error messages (probably the same one as earlier), the first is "Unknown Graphic format" and then the second is "General error. General input/output error." and I get this when trying other options from the list to.
The other documents on the flash drive (spreadsheets and text documents) open as normal. I have copied the document from the flash drive and put it onto my desktop as well. Many thanks (I hope that this is an easy fix 🤞) Mark
