Holy cow, I wrote a book!
Consider the following sequence of operations, assuming that F: is a
USB thumb drive with plenty of disk space.
C:\Users\Bob\Downloads> copy readme.txt F:\
1 file(s) copied.
C:\Users\Bob\Downloads> copy Update.iso F:\
The parameter is incorrect.
Why is the second file copy failing?
The hint is the file extension: *.iso, which suggests that this
is a CD or DVD image, and DVD images have the feature that they
tend to be really big.
Like more than
USB thumb drives tend to be formatted with the FAT32 file system
FAT32 has a maximum file size of 4GB minus one byte.
The user confirmed that the Update.iso file was
larger than 4GB and that the USB thumb drive was formatted as FAT32.
Mind you, the error message doesn't help at all in identifying
that this is what's going on.
I don't know where it's coming from, but my guess is that
somewhere inside the copy command, it tries to create
the destination file and set its file size.
Since the file size is out of range for FAT32, the call fails
with the error ERROR_INVALID_PARAMETER,
and that's what ends up bubbling out to the user.
But at least now you know what the confusing error message is trying
to tell you.
