thanks for your great question. i have ever considered it. i did not do as the way as your advice just for these reasons :
1.these 30 files typed by myself have not finished.
2.if i pack files together as a .rar or .zip, i am afraid i will influence everyone to study.
3.i appologize to you for wasting your time. i should have uploaded them. when all the files were completed, i will finish it in about three days.
