SOLVED Copying Large files results in "._" files of 4096kb AS WELL as the correct file

[melvynadam]

I am using my FreeNAS box (FreeNAS-8.3.0-RELEASE-x86 (r12701M)) as a backup server for my media server.

Using my MacBook Pro, I just copied a large folder (70GB) of material from my QNAP NAS to the FreeNAS box.

The source folder looked something like this:

S01E01.avi 185MB
S01E02.avi 185MB
S01E03.avi 185MB​

The resulting folder on my FreeNAS looks like this:

.@__thumb <Folder>
._.@__thumb 4,096K
._S01E01.avi 4,096K
._S01E02.avi 4,096K
._S01E03.avi 4,096K
S01E01.avi 185MB
S01E02.avi 185MB
S01E03.avi 185MB
​

What have I misconfigured on the FreeNAS or is this somehow caused by using MacOS for the copy operations?

The ._ files are a Mac thing, they're emulating HFS+ features in a non HFS+ filesystem. Delete them if you like, they're completely disposable: all they hold is previews and metadata which you won't care about. Info here.

4096K is very different to 4096mb as in your thread title, though!

/Edited to add: Mind you, I don't get these on my NAS when I copy movies to it. Are you certain they're not generated by the QNAP?

The ._ files are a Mac thing

Thanks. Even though I thought it unlikely that the Mac was the cause, I included that info to be as comprehensive as possible. Will delete them.

100% right but I can't see how to edit it now :(

Well they're not on the QNAP in the source folders and if I copy a folder to my Windows box, using Windows, those files don't appear. So it looks like the Mac is the problem.
