7z

I am using 7za command line

File dfat_clist.xls in directory 2010_05_07

The same dfat_clist.xls in directory 2010_05_08

Zips are created in the same directory where the xls files resides

string pars = "a -tzip \"" + Path.Combine( SourceDir,ZipName) + "\" \"" + Path.Combine( SourceDir, Mask ) + "\"" ;

Parameters given to 7za are full paths for zip and xls. For some reason a couple of bytes are different A7 and A8 values for directories 2010_05_07 and 2010_05_8 respectively. How to achieve identical results and out of curiosity what causes this problem.
