Netdrive2 and Dropbox

I have NetDrive2 on Windows and mount Dropbox as netdrive. When I try to copy a file to Dropbox from a local directory, I get (translated by me from Swedish): “Do you want to copy this file without properties? …The file has properties which can not be copied to the new place …”. When I answer “Yes”, the file gets copied but with todays date!

What is wrong?

NetDrive does not support file streams. But probably files are work as normal.

Dropbox API does not support set file date or time. When files uploaded, dropbox sets a time for file.
