I am trying to copy video (mp4) files from the solid state drive of my MacBook Pro to both a external hard disk as well as to a SanDisk USB thumb drive. It goes well up to abut 4.1 GB file size, but for larger files I get an error message "The item "Filename" cannot be copied. The operation couldn't be completed. File too large".
But the file I am trying to copy is only 4.5 GB, whereas there is about 25 GB free space on the USB thumb drive, and about 1 TB on the external hard disk. Does this possibly depend on the file transfer program? First I tried to use Forklift, and then simply Copy and Paste from one Finder window to another. But always the same error message. I checked if there is a limitation on the size of transferred files in Forklift, but did not find any. I would appreciate if someone could tell me where the bottleneck is.
