VirtualBox and Drive changes

I moved the files for my Windows virtual box from a portable hard drive to an SD card, but when I try to open the file, I get an error about the UUID being used for another device. One command fixes it:

vboxmanage internalcommands sethduuid “[new path/file]”

Combine Files

An easy way to combine files in Windows.  Works perfectly with text files (or CSV).  Use the copy command:


copy file1.csv+file2.csv+file3.csv newfile.csv

Files are copied into one new file in the sequence listed.
