Why cant the files I copied to my sd card work

There could be several reasons why the files you copied to your SD card are not working.

1. Compatibility: The files may not be compatible with the device you are trying to access them on. Make sure that the files are in a format that is supported by the device.

2. Corruption: The files may have become corrupted during the copying process. Try recopying the files to see if that resolves the issue.

3. File system error: The SD card may have a file system error that is preventing the files from being read correctly. Try formatting the SD card and copying the files again.

4. Insufficient space: The SD card may not have enough free space to store the files. Make sure that there is enough space on the SD card for the files you are trying to copy.

5. SD card compatibility: The SD card may not be compatible with the device you are trying to access it on. Make sure that the SD card is compatible with the device and that it is inserted correctly.

If none of these solutions work, it is possible that the SD card itself is faulty and may need to be replaced.
