People suggested formatting to exFAT which is valid, but first you could just try either compressing the file (tar czvf file tarball.tgz for instance). FAT32 cannot handle files larger than 4GB, and compression might just make your file small enough.
As a workaround you could also split it in half and stich it back on the target machine
They get hated on because :
they inspect packets. They terminate the TLS sessions at their servers and reencrypt to forward to the backend. This allows them to analyze the data to spot spam, optimize compression and such
they are used everywhere. If they go down, 30% of the internet goes with them.
