I am lazy and feel handy with in vi.
Since you have a file full of file names
And since I have no clue how the file was generated
and validated.... I want to inspect the file first.
And, if this is a one time action....
I tend to just make a copy of the file
and edit it to be a script. Working in the
editor can permit me to see problems.
cp ./listOfiles listOfiles.sh
vi ./listOfiles.sh
Check the first and last lines,
these not smiley faces but checking will make ya happy.

search for white space and meta characters ... 6 ways to sunday...
a meta char discovery script line would be handy I can never
recall them all. Mostly I just read the file... I do search for the
obvious.

turn it into a scrip.

:1,$s/$/ new-dir/
If ok...
:wq
bash -n < ./listOfiles.sh | less
bash < ./listOfiles.sh
The advantage is that looking at the listOfiles
is part of the process. My partial list of meta
char searches might indicate the scope of potential
pitfalls.
I can search for spaces and meta characters with vim I can also build it in
safe steps to validate the lines... i.e. replace "mv " with "echo" or
"stat"....
I can insert "set -x" to make it noisy/verbose.
If I am going to do this again and again then
I would do some more interesting looping and scripting.
Clearly some safety testing of the input should be
added.
cat listOfiles | while read i
do
echo ===========================
echo $i
mv -i $i newdir
done | less
or...
while read i < listOfiles
do
echo ===========================
echo $i
mv -i $i newdir
done | less
YMMV.
