EXFAT drive to NTFS
Have a look at this: http://forums.guru3d.com/showthread.php?t=373964
Seems like all my research points to "you can't". Other than removing
the data, format it, and put the data back. If it's your OS, that's a
tough one.
+1.

Buy an external drive (you should have one anyhow, for additional
back-up -- reduced odds of losing data). Do what Big Al suggests.

Have a good day,

currently, in one directory and its subdirectories, I have files which
total 26.5 GB, but take up 78 GB on disk

is this the result of using an exFAT filesystem? would NTFS be more
economical with space on disk?

allocation unit size for an exFAT format is 128 kBytes
allocation unit size for an NTFS forrmat is 4096 bytes

this is a no brainer, isn't it? it's got to be NTFS

If the files are ZIPped (even in store mode, not compressed),
that could save space when they're moved to the exFAT storage.

If you made a single 26.5GB ZIP file, you'd only need 26.5GB
to store it. There is no wasted space in that case.

You may have space on the device to do that now. Take the 78GB
used space, create a ZIP which takes another 26.5GB. You need
at least a 105GB storage device, so a 128GB would be the next
nearest size, and would have room for the operation.
Once you're satisfied the ZIP was created successfully,
you can delete the 78GB section. Which frees up a lot of space.
