Question with Modding, G36e to L85a1

OKKK, i have read Gallapoi...umm... forgot your name
anyways, i read his modding tutorial... but changing hex with the files are confusing D:
well...I'm just a noob with poor grammar,
But i still has question!

I know that g36e has a different file type with L85a1, but wondering if theres any file similarity between these 8 files :P

ANI_G_L85A1MOD
CM_HND_NM_DF_L85A1MOD_SH
CM_HND_SP_DF_L85A1MOD_SH
CW_HND_NM_DF_L85A1MOD_SH
CM_HND_SP_DF_G36E_CH
PVMLA_G36E
PVMLA_W_G36E
PVMSH_G36E

KAY....how did you do it corndog? XDDD

CM_HND_SP_DF_L85A1MOD_SH to CM_HND_SP_DF_G36E_CH
CM_HND_NM_DF_L85A1MOD_SH to PVMLA_W_G36E
CW_HND_NM_DF_L85A1MOD_SH tp PVMLA_G36E
CM_HND_SP_DF_G36E_CH to PVMSH_G36E
I do it thataway and it works fine.
