Why is my computer lagging everytime I try to simply copy (or move to another disk which I think is the same as copying anyway) 200 GB of file from my C:\ drive to the E:\ drive (external hard disk) ?
I mean I opened the Task Manager and
process it shows
explorer.exe - 14k. Doesn't look like a big problem with Ram. But I noticed that everytime I try to copy files like 200 GB my computer will be laggy.
What's the cause of the lag here?
