[p4] Editing a Branch spec

[R K]

All,

I have a branch spec wherein i get files from different folders of one
branch (Integration already done ) .I  now want to edit my branch spec such
that i remove source paths for 2 folders ( I do not need them to be in my
branch ) . If i integrate once again will the files under those 2 folders in
my branch  be deleted or will they continue to exist ?

Regards
Ram
