# Troubleshooting Transfer
You cant drag and drop more than one hex file at once onto your micro:bit. If
you try to drag and drop a second hex file onto your micro:bit before the first
file has finished downloading, then the second file may fail in different ways.
When the first program has been written to the micro:bit, the drive will
disengage. If you drag and drop a second file at this point it may not find the
drive and the second write will fail.
The errors may look like this:
**Windows**
![](/static/mb/device/usb-windows-copy-file-error.jpg)
**Mac**
![](/static/mb/device/usb-osx-copy-file-error.png)
Or it may appear that there are two hex files on your micro:bit so the micro:bit
wont be able to run multiple files. To rectify this, unplug your micro:bit and
plug it in again. Make sure that your micro:bit appears as `MICROBIT` and not
`MAINTENANCE`.
