I have some new music on my SD card and Winamp it's not showing it. How can I load the new files.
According to the information wormed out by the comments, the culprit seems to lie in the way the files have been transfered – as the transfer method chosen obviously didn't trigger the media scanner.
Explanation: Most media players rely on the media database (a SQLite database) to find available tracks, as a simple database query is both faster and less battery consuming than scanning all available storage. Hence the latter is left to a single app, the so-called Media Scanner. Once triggered, it scans all available storage and feeds its finds to the SQLite database. This Media Scanner is triggered by different events: following a device boot (
boot_completed), mounting a storage (e.g. putting in a SDCard), and unmounting from USB Mass Storage are some examples. So if the files were copied e.g. via some WiFi app, and the Media Scanner had not explicitly been triggered, those players won't find the new files.
Work arounds you can assume from the explanation: umount/mount the SDCard, or reboot the device. Both not really elegant. Alternatively, check the Playstore for some helpers like SDrescan, Media Scanner, or Rescan Media, which are simply triggering the Media Scanner when you tap their Widgets.
