Error while copying files to flash drive

When I copy files & folders from my macOS Catalina (latest version) to any of my flash drives in ExFat, I receive this error message.



But when I copy the same files & folders from the flash drives to my MacOS then it works just as fine.

MacBook Air 13″, macOS 10.15

Did you create this exFAT USB drive on a Mac? Backup the files from the USB stick and use Disk Utility to erase the whole physical USB stick. Within Disk Utility you need to click on "View" and select "Show All Devices" before the physical drive appears on the left pane of Disk Utility.


If you still have problems, then try using another USB stick or another even another brand since the quality of USB sticks is quite poor.
