copy large files fails in explorer

If I copy 3+ or so total GB of data, explorer slows and eventually fails.
copy one movie of 1GB = OK
copy next movie of about the same size = OK
copy 3rd movie of about the same size = fails
I can reproduce this every time.

If it matters, I am copying from SMB network to external SATA HDD

 

so. HDD connected to x9s. x9s connects to a samba share. and you wan't to copy from samba to hdd ? HDD is formated NTFS/GPT?

 

copy works, what I am saying is that if you copy a lot of MB, then it will fail.. Like a memory leak or something..
once it fails, I need to exit explorer (if it didnt crash), clean up, then copy the next 2 files... etc...

 

also if you copy a bunch of smaller files, bmp's for example, there will be no problems.
Only bigger files like movies (1GB plus)

 

Did you try external explorer ?

 

no. I have installed ES file explorer for this reason, but for the life of me I can not get it to see the network.. so I gave up on it
