Actually, if you check the exported CSV file with a text editor, you should see the Full Filename (both header and values) is/are wrapped in quotes. There appears to be a bug in Excel so that if you right-click the CSV file > Open (in Excel - or, accept the FOC prompt to open it, which does the same thing), Excel will strip the quotes from field-1. Go figure...
If you open Excel 'empty' and Import the data (CSV file) into a blank worksheet, and jump though the hoops of telling it what wrapping character (") and delimiters (,) are used, it Imports perfectly fine for me. I even tested it by adding a comma (with a text editor) to a filename of an EXE, and it Imported fine using the manual method (comma present, but no field/column-break occurred).
