import multiple modules & forms from multiple files into destination file

[Alaa mg]

hi

is there any some procedures to bring modules , forms with all the codes are existed into them from multiple files? for instance the destination file is OUTPUT when I open file should brings modules( SAL1,PUR1,MN1) and forms( FRM1,FORM2,FTR3) from file INPUT and bring modules( INV,CATE,MM) and forms( RET1,RET2,PPT) from file SUMM

so the all files are existed in the same folder .I wouldn't do that manually to open file and copy the modules & forms and paste it will take much time .
thanks
