I have a spreadsheet that has different cells linked to other cells in other sheets in different workbooks. I sent one worksheet as an attachment to a colleague who changed some of the data. When she sent it back, the links in the formula bar read C:Attach/ instead of C:MyExcelFiles. I can go in manually to each cell and type in the correct path in the formula bar, but my question is: Do I need to in the future send her all linked files and have her put them in a folder with the same name as the one on my computer? Or is there another way. Thanks very much.
