Windows 10: Nested Folder copy/moving hangs for several minutes per folder creating insanely long copy...

Greetings, I am having an intermittent issue with Windows 10 and the handling of nested sub-directories and moving them around my hard drives. An example would be Unraring a file with 8 folders, each folder having 2 sub-directories and 50 files of various types per folder. Unraring the entire example took 7 hours and 41 minutes. Manually moving each folder took around 4 hours, and manually creating each folder tree and only moving the files from folder to folder took about 13 minutes, most of which was making directories and navigating them before copying files. If I manually create the directory tree, then try and copy everything, I get the same result as if I hadn't created the directories at all.

I don't run 3rd party file scanners, I don't run windows defender, I don't even have indexing or windows search enabled.

I've tested this with many combinations of conventional hard drives, ssds, usb drives, rar files, zip files, CD/DVD/BD-Rom images or real media, even a tape drive.

There appears to be one exception to the horrendous speed. If it's a zip/rar file that's been packaged as an MSI installer or generic executable, there isn't any slowdown and the files extract in a timely matter.

I've had this problem going on a couple months now and it hasn't really been a major issue until I went to grab a latest git repository and have 300~ directories and associated files. It's been copying in the background for a little over two days now.

Of side note, explorer.exe stops responding between bursts of file progress, but there are no other ill effects on the system. I can access files and programs on the drives in question with no latency beyond normal HDD seek times.

Any thoughts?

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
