Copy 20 files at a time from drive G to drive H
Running Windows 7 Pro on a Dell T3400.
I need to copy a large number of files from drive G to drive H. Both drive G and H are usb drives. They are connected to the T3400.
Drive G contains files in multiple directories.
Currently drive H has no data on it.
The T3400 is not a fast computer. Drive G has about 20,000 files on it. If I use Robocopy to copy all the files on drive G to drive H, the I/O is going to slow down the computer considerably.
I'd like to somehow copy say 20 files at a time from drive G to drive H
My knowledge of system programming and scripting is limited.
I thought if I could create a simple batch file containing file names on drive G then I could edit the batch file and make sure only 20 files were listed in the batch file.
I tried creating a list of files to be copied by using the DIR command:
G:
Dir *.* /b > c:\filelist.txt
This produces a list of files but some of them are listed as:
G:\Movies\Purple.avi.<Dir>
I don't know how I would be able to write a script which would remove the <Dir> from the list.
There must be a simpler way to do this.
What process would you create to perform this task? Please give me a DETAILED answer.
Thank you.

the /IGP parameter could be used to slow the copy down, so it could run in the background without slowing the machine much. Try with maybe /IGP:100 then adjust as needed.
If the drives are identical sizes, image G (data) to H (empty) using your favorite imaging tool. Most good imaging tools allow throttling the transfer bandwidth.

Mr Prew:
If I could wish for the perfect solution:
- some application which could copy 20 files and know the name of the 20th file so it knows where to start again.
- OR I could leave my pc on all night and the copy application could detect the overall amount of I/O use and note when the I/O had decreased so the copying could use more system resources.
Also, I included the /B option in my Dir command and still there were the strange characters after the file name.
Mr Green:
Thank you for the link. I will try this.

Mr. Prew:
Yes, I tried the /MT:1 option, Robocopy was running all night and was still running in the morning.
I am not an expert with Robocopy. It seems it can produce a list of files. I'm going to be away from my pc until Saturday so on Saturday I will see if Robocopy can create a list of files.
If so then I could edit the list and see if I can find a way to insert an xcopy command on each line in the list file.
Why xcopy? Well, I don't know of any way to feed a list of files to Robocopy and have it copy files in a list.
Yes, I will look at UltraCopier . Did not know this exists so I really appreciate this links you provide.
Nobus:
You have been very helpful in the past. I'll try Richcopy on Saturday and let you know.
