Is this true, because if the slowdown is great, >>I may want to reconsider buying AD (or give up Filesaver). The problem here is not so much the slow down, but the fact that FileSaver is rendered ineffective by programs that generate lots of temp files. This is because file recovery utilities keep a record of only the most recently deleted files. Consider the case in which you delete file x, after which AD runs, creating and erasing enough temp files so that x is no longer on the recovery list. When you notice that you deleted x in error, and try to recover it, you are out of luck. Not that for similar reasons running a disk optimizer (such as Disk Express) makes file recovery much less reliable. This is because the sectors used by the file to be recovered might have been reused in the optimization process, overwriting the original data. In short: It is probably a waste of resources running a file recovery utility, a defragmenter, and a compressor all at once in the background. Edgar Knapp
