Why do small files take longer to copy?
Metadata. Every time you copy a file, the system must also copy over some metadata. Things like the filename, creation date, modification date, filesize etc. If you copy a mix of large and small files, the computer can’t figure out how long the copy will take, so just adjusts the estimate as it goes along.
Why is Windows slow at copying small files?
Small file transfer is slow During file transfer, file creation causes both high protocol overhead and high file system overhead. For large file transfers, these costs occur only one time. When a large number of small files are transferred, the cost is repetitive and causes slow transfers.

Windows 7 and newer versions come with a new version of the robocopy command that is able to copy files much faster then the normal copy command or copy function of the file explorer by using several simultanious threads.

What’s the best way to copy small files?
Robocopy can copy in parallel, which can take advantage of off-loaded disk and network IO. I’d set the parallelism to 4 in your case as this seems to provide the best throughput for small files. Was this post helpful? Thanks for your feedback! This person is a verified professional.
How to copy first n files in different directory?
A pure shell solution (which calls cp several times). This copies a maximum number of $N files from $srcdir to $dstdir. Files starting with a dot are omitted. (And as far as I know there’s no guaranty that the set of chosen files would even be deterministic.)
How big are the files on my computer?
I need to relocate 4 folders from one computer to another. Both computers are on the network, and I can access the source and destination folders from anywhere. The issue I have is that each folder contains anywhere between 150,000 to 350,000 files, each file being very small (typically under 50kb).
