Handheld devices
If you've managed the files on it through anything else apart from MC (eg deleted files off if while at work) there appears to be now way of getting MC to just recheck the free space on the device
You can get in a situation where MC won't let you add any files, reporting that the device is xMb over capacity
If you've deleted everything off the device, there's nothing for MC to delete and you can't add any more, and you can't get it to realize that there's free space
Please can we at least get the refresh button to recheck the free space
[edit]
Quitting MC, deleting the 2 RJiver files off the device and restarting MC works, but it's kind of 'hacky'
