Excel 2003 file header/trailer bytes?
I was interested in identifying Excel files (for recovering lost files). I had a look at some Excel 97-2003 workbooks, and they begin: D0CF11E0A1B11AE1 (hexadecimal) Now I download a 250-page document from openoffice.org purporting to be Microsoft Excel File Format but it does not show this string of bytes as the "beginning of file" I hoped to find out what bytes indicate the end of an Excel file. Many file formats do have some footer/trailer bytes, and I wished to know what is the end of an Excel file looks like. I could look at some files with a hex editor, but is there an authoritative reference for this at Microsoft? |
