Ext2 on SD card how to read and write to it

Dear Experts

I am using windows 7 and before partitioning my mobile's (Samsung Galaxy S7) SD card I did backup to all folders that were installed on it and those apps were moved by AppMgr III (App 2 SD) .

Then I partitioned the SD card using the utility called "Mini Tool Partition" as per the snapshot below (SD card named as Disk2 not 1 and size is 32 GB)

I created 3 partitions as per some online recommendation and as below :

8 GB Fat32
16 GB Ext2
8 GB Swap

Using my laptop slot that is designated to SD card I wanted to copy the backup to the partition Ext2 which utility will let me do that ? because when I copied them back to the SD card Fat32 partition phone was not able to read those apps !!!

So far I tried ext2explore and Ext2Fsd-0.68 with no joy
