Talked to you in ICQ about this one luks... If available space on destination drive reaches zero, PicardQT keeps processing files. You said there wasn't a way that was cross-platform to detect the current remaining hard drive space. However, when this happens, Picard DOES stop deleting the original files (luckily). Is there any way to have Picard check after it processes each file, and if originalfile still exists, have it assume zero drive space has been reached, pause for user intervention, then on un-pause, re-try that file and keep going?
