How does SolidWorks ePDM manages physical files in Archive server ?

For one of assembly, we are having total 8 versions in SolidWorks EPDM . Let's say the name of Assembly is Abc.sldasm and this file is having version 1 to 8 . Version 8 is latest version .

I checked in Archive server folder structure only some physical files are present .

00000001.SLDASM.gz (file for version 1st)

00000002.SLDASM.gz (file for version 2nd)

00000003.SLDASM.gz (file for version 3rd)

00000006.SLDASM    (file for version 6th)

So it means files only for version 1 , 2, 3 and 6th is present then where are the files for version 4th , 5th ,7th , 8th are stored ? Is it default behaviour ?

At list for latest version 8th Physical files should be there. If it is not there from where EPDM will open the file ?

Thanks in advance .
