Read/write very large xl2007 files

[spreadsheet1]

I have used 1000s of XLSB Binary files without an issue for almost 3+ years. The larger the file (e.g. 10MB+), the larger the time & disk space saving obviously (sometimes up to 80%+). File size reduction is very useful, if files are uploaded to Sharepoint, email attached etc.

The only drawback I can think, is that the Excel file cannot be rename to ZIP and unzipped or used with some 3rd party Excel software that read only xls,xlsx & xlsm.
