You’ll then learn how to remove the “Read-only” mode from an Excel file in multiple ways, including changing from a “Read-only” workbook to an editable Excel file, disabling “Read-only” by unprotecting an Excel workbook or sheet, and how to edit a “Read-only” Excel file by changing its properties.

Excel will show the following message: “To prevent accidental changes, the author has set this file to open as read-only”. For collaborative work, Excel also allows users to share an Excel file in “Read-only” mode to restrict editing. For example, to avoid data loss, to stop other users from changing formulae, or to maintain a specific format for your data. Browse to the folder where you store your Excel files, select Subfolders of this location are also trusted, and click OK.Excel allows users to protect data on various levels, depending on the reason.

The same thing happens if I double-click an Excel file in Windows' File Explorer while is open in Excel.

To free disk space, delete files you no longer need from the disk you are saving to.To make more memory available, close workbooks or programs you no longer need.Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space. When I have open, and try to open a file using File » Open in Excel's menu, I get this error: "Microsoft Excel cannot open or save any more documents.
