Hi,
When it comes to "copying" songs from floppies to the SDCard, or from hard disk to SD Card, vice versa, or from SD-Card to SD-Card, or from one folder to another on an SD-Card ... the tool with best price performance for this task is the KN-SDExplorer tool.
Note: the tool runs on Windows 2000 and Windows XP guaranteed. For older Windows I recommend to download and install the demo version from the site and try it out. For Windows ME it might run, depending on the hardware (USB connections).
You can use any SD Card reader.
