I (as well as many others I'm sure) use Dropbox to sync with offsite professionals while needing to use multiple workstations. Rather than keeping local copies on each of these computers (as they aren't private workstations and often are cleared), I keep my Dropbox on an External drive.
I've now been presented with a need to utilize this system over multiple OS, and have just found out that Dropbox cannot be linked to an ExFAT external drive.
The 4GB file limit has been removed with FAT32, and many professionals have to utilize multiple OS environments to do their job. This is a problem with a solution that's far overdue.
Please let me continue to use Dropbox to connect with other professionals regardless of the OS I am working on in that moment.
