Maybe, all in just one script?

Note: Not tested
Code:
set -x # to output to screen the execution of the script

while read f d
do
    if [[ -n $d ]] && [[ -n $f ]]
    then
        filepath=$(locate $f)
        if [[ -e $filepath ]]
        then
            mkdir -p "/home/data/$d" && cp "$filepath" "/home/data/$d"
        fi
    fi
done < data.txt

Detailed Description

       e.g. is it a file, a directory, a pipe etc.

Constructor &; Destructor Documentation
   zipios::FilePath::FilePath (const string &path = '', boolcheck_exists = false)
       Constructor. Parameters:
	   path A string representation of the path.
	   check_exists If true is specified the constructor will check the existence and type of the path immidiately, instead of deferring that
	   task until it is needed.

       Definition at line 18 of file filepath.cpp.

Member Function Documentation
   void zipios::FilePath::check () const [protected]
       This function sets _checked to true, stats the path, to see if it exists and to determine what type of file it is. All the query functions
       check if _checked is true, and if it isn't they call check(). This means stat'ing is deferred until it becomes necessary.

	   true If the path is a valid file system entity.

       Definition at line 129 of file filepath.h.
