e.g.
s3-zldww.rar
s3-zldww.zip
s3-zldww.7z
s3-zldww.001
s3-zldww.abc
what is at the end of the file name
You may need to go into folder options and set it to show known file extentions to see them
extract the first zip file then and only the first one, the other files are auto linked/extracted when you extract the first
Probobly named s3-zldww.001/s3-zldww.002 ect... you can't see that because windows explorer is set to hide known extentions
