Possibly. I've exported a virtual 1PB filesystem to windows clients and the=

appeared to handle it ok.

XFS will handle this just fine. Be aware that xfs_repair may take a fair
amount of time and memory on very large filesystems. IIRC there was some
scaling work done recently, but I'm not sure if it made SP3.

I've never seen modern windows clients have problems with large files of
filesystems. I don't expect you will have problems.
