if [ -d $1 ]; then DIR=$1
else echo "Wrong directory"

if [ -f $2 ]; then STOP=$2

Please note that "Dir_B" is hard coded (not passed as an argument because you didn't request this).
Note further that I put "echo" in front of "rm" and "cp" so you can test the outcome.
Remove both "echo" statements for the "real" processing to occur.
The source directory should not contain any subdirectories to avoid error messages.
If there are such subdirs please let me know.
Finally, please note that the script does preliminary checks for existence of the source directory and the control file.

Small correction is needed. Only the files in the list.txt are getting copied to Dir_B. The directory structure is not preserved. For example: if the text file has abc.txt as one of the entry and the file abc.txt is in a directory under test1/test2/test3/abc.txt.
test1/test2/test3/abc.txt instead of just abc.txt
Sorry about the confusion !
