You chose Save, but the specified file was modified outside the Quartus II software. As a result, the open version of the file, which contains unsaved changes, is different from the saved version of the file, but the Quartus II software cannot allow two different versions of the same file to exist in the same directory. The Quartus II software is asking whether you want to overwrite the saved version of the specified file with the open version of the file, which may result in the Quartus II software overwriting some or all of the changes made to the file outside the Quartus II software. |
