Windows 7: Multiple copies very slow

Multiple copies very slow

If I multiselect 2 folders and copy them to a destination across the network vs select the same folders separately to copy to the same destinations (2 copies), the time difference is unbelievable. Sometimes I cannot always mutliselect them (different folders). Is there any way to make it copy faster?

My guess is Windows 7 is throttling between the 2 processes making it like 5x as long.

I know I can do one copy, then the next, but sometimes I want it to be done at one time (I'm not sitting there watching it).

I was hoping to avoid batch files as these are 1 time things usually.

I guess I would think Windows is smart enough to know I am doing 2 copies with that same source drive and destination and work it out.

The data transfer speed is set to the network, so what ever your network transfer data rate is, that's what it is. This it do to the hardware of each PC and the router on the network whether wired or wireless.

Not true.

Try picking (multi-selecting) 2 large files and copying them somewhere on your network and time it.

Then pick the 1st file, and copy it. Then pick the second file and copy it (at the same time the first copy is going). This method will WAY slower than the prior one.

What is the transfer rate difference?

It varies.

Think of it this way though. A hard drive can only read from one place at a time. If it has to constantly switch from one file (assume little fragmentation) to another, that involves overhead. There is also (I imagine) overhead in Windows switching between the copy processes, but this is probably minimal compared to the hard drive issue.
