Take the 2-minute tour ×  I had an ISO file that was over 4GB.
When I tried to copy or move the file from my computer to a USB
key, I remember getting some error about the file being too
large for the operating system to move.  So then I ran this
command to have tar break it up into a disk1.tar and a
disk2.tar:  tar -c -M --tape-length=2002400 --file=disk1.tar
bigfile.iso  Once done, I copied the file onto USB. Now when I
try to put the file back together, I ran the command:  tar -x -M
--file=disk1.tar  But I get the error  tar: Archive value
4209604608 is out of off_t range 0..2147483647 tar: Exiting with
failure status due to previous errors  So my question is how do
I move a large file from my computer to a USB key? I even tried
SFTP the file from one server to another, and it also complained
about file being too large.  share|improve this question What

it to another filesystem.
