This issue declared in version 3.08 (October 2006) is still active in the second edition of version 3.10 (January 2007).
In year 2007 i think that on entreprise grade products, an FTP server MUST have resume fonction activated for many reasons :
It is just a parameter in a proftpd config file
It is the most useful feature of an FTP server
It is an entreprise feature where you can't lost the time you spent transfering 40Go during hours because of a temporary network failure
The issue was declared 1 update ago and more than 2 month ago.
We are speaking here of a code of practice... so please, give "NAS-XSR" Entreprise version real entreprise grade features.
Thanks a lot,
