Windows 10: Copying Files

There is something I observed while bulk copying : The copy speed while backing up 100s of GB of data from one Hard Drive to back-up drive.


I wonder it is a problem of windows or a problem in my system?

When I, say copying a smaller amount of data (for example 30-40 GB chunk) - the speed of copying shown is X MB/S, but when I select the whole thing (which is of the order of few hundred GB), the speed drastically falls, almost to half this speed. I am using conventional ^c and ^v approach.

Is it some sort of document map it is retaining in RAM, so that the left out portion of RAM for use is reduced ? That would be completely unnecessary.

Though it is copy all (there are many sub folders too), but since the main destination and source folder have different name, I didn't copy the whole folder, but rather selected all the elements in the folder and then use copy paste. (In DOS it would be something like copy D:\X1\*.*/s G:\x1_bak\, but here we don't have the copy-all command, so these have to be selected)


Has any one else observed/ noticed it ?

Java.nio.file - Copying files

You can't copy a folder, thats why it generates an exception (you are trying to copy a folder using a copy file function).
You probably need to list all the files inside that folder and copy one by one

Issue was the above, so thanks temp02.

 

How is copying files in Windows 10?


I created a feature request listing on Windows User Voice to propose the inclusion of advanced copy management options. People can vote for the idea if they also want it, here:

Provide advanced copy file options in the manner of checkboxes in the transfer window to designate what to do with certain types of conflict – Feature Suggestions for Windows
