[BUG] Moved file has size 0

(1/3) > >>

Hello again,

first of all, loved the product and I think you are doing a great job. I was ready to move from tc to mc but I discovered a bug that I think is a very big one. When I move a file, or better said, when I want to move a file from my local drive to a mapped network drive, sometimes it happened that the original file is deleted and the file on the mapped drive has 0 size (I checked in the windows explorer it also says 0). In the whole procedure everything is ok, it says it is copying file, the computer and the network take their time (I can see the data being transfered in my network monitor), then it says it is copied and that everything is ok, then the file from my local drive is deleted and the file on the mapped network drive has 0 size.  If you want I can do more tests to see if the problem is related to only a specific extensions, does it occur in special cases, or anything that would help you solve the problem.

I would also like to mention that the network drive is running just fine and doesn't have any problems.

That is very strange.
I never seen that and no reports of it.

When moving a file the file is first copied and then the source is deleted, The source file is not deleted unless it successfully copied the file to the target.
It actually is verifying the target file size is correct before deleting the source file.
So how it can delete source file when target is 0 is very strange.

What is the network location.. Another Windows Server ? NAS ? Linux ? Mac ?
Any error in any log on the server ?
You are sure that there is no file system issue on the target device ? I seen file go to 0 if the filesystem was corrupt. specially on some NAS devices.
What does the fileoperation log in MC say ? Any error there ?
Do you see the file grow in size during file copy and then end up at 0 ?

NAS DLink DNS-320 with two WD Green 2TB drives in RAID 1 with static IP address. I haven't seen any error report on the NAS.

The problem shouldn't be on the device since TC worked with it for 1+ year and never had any problems.

I made a small video showing you what is going on... I think it will answer many questions...

Strange. In both cases zero-sized file is the same. Looks like antivirus deletes content after file is written.

I tried to copy and move those exact same files, from those same locations, to the same location with WE and TC and everything was fine. Didn't get any error or antivirus / firewall warning....

I should mention that this only happens in MC when I copy to the Z: drive aka. network mounted drive, when I try to move from one HDD to another in my PC everything is fine. It also happens when I access to the drive / folder via the Network (in the drop down menu).
