You are welcome. This is safer than Copy/paste: Context Menu - Add Copy To Folder and Move To Folder
I recommend TeraCopy Portable as being infinitely safer than Windows native copy/move.

I used Windows Drag/Drop to copy something like 12 files totalling 30 GB from my secondary SATA HDD to a USB2 connected external HDD.

My files were Macrium Partition Image backup files, and most of the copies failed Macrium's checksum based validation immediately after copying.

Immediately, without dislodging the USB2 connections,
I used Teracopy and that did the transfer perfectly.
It retries appropriately any file that is temporarily in use,
rather than an immediate abort of the whole series of pending transfers.

Even better, after transferring it remembers the MD5 hash checksums for each source file,
and then reads back all the copies and computes checksum and compares with the original source checksum,
and if required then retries all the failures.

My files may have been corrupted by some intermittent glitch in the chosen USB2 port,
and Windows never noticed any difference between the original and the copy it made.

I am using version 2.0.1.0

I believe 2.0.5. is better, available from
TeraCopy Portable Download - Softpedia

The latest version is 2.2.7 from the developers at
Code Sector Blog » TeraCopy

CAUTION :-
I have not tried the latest.

In the past the Free Portable did not have all the bells and whistle of the Licenced and Installed version.

Both versions are now at the same version 2.2.7,
but I understand the Free Portable has cripple restrictions - just like share-ware,
and perhaps Crippled 2.2.7 has less capability than my free 2.0.1 or SoftPedia free 2.05.
