Cannot copy file, file is in use

Update:

The problem is finder.

I tried double commander and mucommander and all worked fine. The files were copied and no error message.

So there is a way to use finder to copy file on NAS?

Yes.

a little update: The copy works sometimes but i didn't find when and how.

the last one works when i disabile the icon preview in the wdtv ( after I tried to copy the file for 20 times). But i try many other times this method and it didn't works.

I think there is a problem with finder and how it managed the file.

Like I written on the first message is an WDTVLIVEHUB.

on the web I find that is a common problem (not only with the WDTVLIVEHUB , but with other NAS (ex. Synology))

And it all started with lion (lack with the samba protocol).

update:

both mucommander and doublecommander transfer files with the speed of 3,2MB/sec instead of 9-10MB/sec. I think that there is a problem with finder about the speed of transfer or maybe with the properties of file

as i written on the first post i try about everything.

before i write this post i search both on apple and wd support forum but no one resolve this issue. Sometimes the suggestion to try in cifs or disable preview works for one file but when i try to copy another file the error represent.

I repeat what i suppose: there is a bug on finder (maybe the preview of the file - they are video file - and disable it doesn't work, or maybe how it can handle the connection...i don't know...security on the transfer o check the file integrity).

as i said i tried the smb and cifs connection (the afp doesn't work). And both in ways i have the same errors.

With my notebook with windows 7 all went well. With my desktop with windows 8.1 all went well. I pick an old pc with windows xp and the copy went great.

With osx yosemite (and as i written lion, mavericks) the copy doesn't work. Strange is that the copy interrupts at the end of the process and not when it start.

So i think is a problem with the preview of finder. But ,like i said, even though i disable it (on the wdtvlivehub or in finder or in both), it works randomly (one file copied, the next two doesn't).

Like i said with mucommander and double commander (two files manager) all goes well.

i don't think so.

If you read on the web not only the wdtv but many other nas owner had problem from lion to yosemite.

Most of them said that is the new smb protocol that affect the transfer of files. Other suggest to disable the preview. Still nothing of this works (works sometimes but not always).

So ,as i written in the message above, if a system with windows (from xp to 8.1) works, i think is a yosemite (and lion and mavericks) problem. Specifically is a finder bug in some ways (the preview, the smb protocol...i don't know) expecially when two programs (mucommander and double commander - two files manager) succeed on the same OSX.

wait wait wait maybe i found the culprit.

during the thousand test 😉 i make, i created an other administrator account.

In this account i notice that the movie file are associated with quicktime while in the other account they are associated with mplayerx (a player that can play almost evevrything and with subs).

So i try to copy over 1,8 GB of video e subs file to the WDtv and all goes well.

So.....do you have any suggestion to which player i must download (no vlc and no mplayerx)? 😉

Thanks for you patience and i hope this may help someone else
