MS-DOS Batch – copying files between directories

This weekend I took advantage of a free time and I did a task for a friend of mine. He had a specific situation that I decided to solve with a MS-DOS batch. To remember my old times as MS-DOS programmer.

The situation was: a series of mp3 files with coded names that were repeated. Because they were formed by a vinyl-to-cd recorder such that – FILE001.mp3, FILE002.mp3 and so on… And each album was saved in a folder named also coded as FOLD3001, FOLD3002, FOLD3003… My task was: move all mp3 files saved in each folder to ONLY ONE folder as repository and destination.

Graphically represented:

+— FOLD3001
|                           |— FILE001.mp3
|                           |— FILE002.mp3
|                           +– FILE007.mp3
+— FOLD3002
|                           |— FILE003.mp3
|                           |— FILE004.mp3
|                           |— FILE005.mp3
|                           +– FILE007.mp3

So what was my solution? Copy each file to destination folder before replacing its name to one that is preceded by folder name where it is originally saved.

This way:

         |— FOLD3001_FILE001.mp3
         |— FOLD3001_FILE002.mp3
         |— FOLD3001_FILE007.mp3
         |— FOLD3002_FILE003.mp3
         |— FOLD3002_FILE004.mp3
         |— FOLD3002_FILE005.mp3
         +– FOLD3002_FILE007.mp3

To get rid of possible filename collisions.

Thus, follow my two batch files to solve this special problem, but that could be adapted to many other similar situations envolved files and directories to move, copy and rename.

To execute this program:

  1. just copy these 2 files (“renome1.bat, renome2.bat”) to a same folder;
  2. customize according to your preferences: working variables (origin and destiny) in “renome1.bat”
  3. open a ms-dos command window;
  4. run “renome1.bat”;
  5. wait for final result.

Enjoy code!
