Optimizing Copy and Paste from one workbook to another in VBA - performance

Question

I have several .xlsm templates in a folder. I'm trying to read through all the excel files in that folder and based on the type of the file, it reads through all the sheets in each file and copy specific cells into another my active workbook (ThisWorkbook).
Following is my code and it is working correctly. However it is super slow. I'm looking for any solution that can speed up the code. I've already tried Application.ScreenUpdating = False but still it is very slow. It takes about 10 min for 20 files to be processed.
DO you guys have any suggestion on how to increase the speed.
Thanks Veru mich in Advance

Answer 1

I Just realized that the slow performance is due to the formulations that are written in the excel but are linked to the ranges that are pasted from the Macro code. As it was addressed in the previous stack overflow solutions, I simply added "Application.Calculation = xlCalculationManual" in the beginning of the code and "Application.Calculation = xlCalculationAutomatic" at the end of the code and now it is much much faster.
I hope it is also useful to whom is reading this
