If there's money in the budget for a few HDDs, does that avoid the problem?I just need to do a disk space check at the beginning otherwise it will break down when the disk space is too low. I'm no programmer really. I call other programs in the batch file and use a load of error checking along the way. I'm pretty pleased how it's turned out so far considering all the complexity I've had to add.
