When looking at the composition in excel in xls format, I noticed that there is a section in there that is XFS, which represents the contents of the set of XFs.

XFS = 16* XF [XFCRC 16* 4050XFExt] I think it means that there are 16 XFs, and then the next XFCRC is optional, and then this 16 * 4050XFExt is really do not understand the XFExt is also a structure, I only know that the 4050 is the maximum value of a composition in the XFExt!

Because I put the WPS newly created an xls parse out to see the next, I newly created this has 64 XF, so here 16 * XF, is a multiple of 16 XF?

There are also similar

FORMATTING = 1* 510Font 8* 218Format XFS *DXF STYLES [TABLESTYLES] [Palette] [ClrtClient]

This 1* 510Font 8* 218Format don't even understand what it means?
