It recently came to my attention that on some NAS devices, the copy of very large files was extremely slow (hours, when it should be minutes).
This was caused by a prior change that attempted to have the progress bars report more accurately – but with the downside that some modern NAS boxes don’t like that.
This release allows the windows file cache to work normally, and has a few other tweaks to try and optimise file copy throughput.
Progress bars may pause at the end of a file copy – this is normal.
