Portable SSD Portable | Extreme | Extreme Pro SSD

I tried copying a folder of 101GB to my brand new Sandisk Extreme Portable SSD 1 TB. When i click on the folder (i am using windows 10) in the properties , i see the ‘Size’ field shows correctly the original size of the folder on my drive C: (toshiba 512 GB ssd) as 101gb, but the ‘Size on disk’ Field shows 220GB.
why is this and what is the solution ? this means i will only have less than half the capacity of the disk.

As recommended by Sandisk support, I reformatted the disk with NTFS format and it solved the problem.
