Hi all,

Please let me know which one takes long time. Cut+Copy+Paste or Copy+Paste?

The only difference between cut+paste and copy+paste is that copy duplicates the file in a new location and stops, cut duplicates the file then deletes the original. So cut has one more operation which will take a little longer, but not significantly.

One exception is if you move (cut+paste) a file to a different location on the same drive partition, the file doesn't actually have to be copied, it can be left where it is and just the file directory changed so it shows in a different folder. This is much faster than copying the entire file. So moving within the same drive letter, copy+paste takes longer than cut+paste.

Really helpful,Thanks.

I have another question, which file is first getting registered/installed/deployed at the OS boot up.

Well, that varies between types of computer and operating system. In principle, bootstrap code in the boot sector of the system's boot device (eg hard drive) determines what executable runs first.

With an IBM compatible, the CPU must start in Real Mode, whereas a modern operating system requires Protected Mode, so for an OS like Windows the first executable that runs is a Real Mode Loader. It starts in Real Mode, switches the CPU to Protected Mode and commences loading the OS kernel. In 32-bit NT-based Windows it's called ntldr.exe, but I haven't investigated if a 64-bit OS is structured in exactly the same way, just with 64-bit executables.
