Hi there, I am on a MacBook Pro 2019, Big Sur 11.2.3, Memory 32G, processor 2.3GHz 8 core Core i9.
I am trying to copy a folder to my u-disk, the file size is 17.19 GB (contained formats: OTF, TTF, WOFF, WOFF2)
after compressing, the size reduced to 11GB. However, I got an error 1309 when it's getting close to end. I wonder why this happens and seek for a solution.
Thanks for your help.

Mac OS error -1309 (fileBoundsErr): file's EOF, offset, mark or size is too big
if you are copying an especially large file, the destination drive format may not accept a file that large.
Otherwise, the file may be damaged.
Volumes formatted as FAT32 can't be used to store files that are 4GB or larger.
