I personnaly download to an unshared folder!

sometimes MP3s are not of very good quality, even chopped of in the end. So I always download 4 or 5 times the same "title" but has different size and/or bitrate. then I share the good files only!

same goes with compressed stuff... I always check if there is a virus, if the zip is damaged, etc.

this way I can filter out the fake files (text files disguised as porn links, or downloaders through a high cost overseas call!)

unfortunately... my files would appear in other's search result as a file with the same name, same size, but not grouped with the original source!

limewire already test MP3s if they are corrupted or not when finishing the download... it should also test ZIPs and RARs, or at least let an antivirus check the files before sharing them. There should also be a more advanced file manager so you can create subfolders, save or move files within a shared folder...
