As far as I'm aware, Xxcopy doesn't have a file size limit
but the destination disk may have. See the following for
the file and volume limits of various disk formats:

Basically the max file size is 4GB for FAT16/FAT32 and
16TB for NTFS.

If you can copy 8GB, that implies an NTFS destination so you
should also be able to copy 100GB. The only things that come
to mind are:

1. Insufficient room on the destination for both the existing
copy and the new copy. By default, xxcopy checks that there
is enough free space on the destination for the file before
copying. This means that there must be enough room for 2
copies of the file. You can disable this check with /ck0
or delete the destination copy beforehand.

2. Maybe there's a bug in Xxcopy. What errors do you get?
Create a log file and use the /oe3 parameter to get more
detailed info on any errors e.g.

xxcopy \src\ \dst\ /oa:xxcopy.log /oe3

3. If the src or dst is a network drive, I've read that there
are some limits transferring large amounts of data with some
protocols. I don't recall the details but you can try using
something like COPY or XCOPY or ROBOCOPY to see if the same
limit applies i.e. can you isolate the problem to xxcopy only?
