Medadata files associated with BitTorrent tool can be saved with .ZED extension. ZED files are of the BitTorrent Metainfo format and are similar in structure to .Torrent files standardized by BitTorrent Inc.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the ZED file after converting to UZED may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from ZED to UZED to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting ZED to UZED does not meet your expectations, you can simply try to find on the Internet a different version of your file in ZED format, properly converted to a UZED file by someone else. If this fails, use the information provided in the further part of the website.
Unfortunately, if after performing the two previously described steps (trying to find your ZED file converted by someone else, and the attempt to convert it to UZED on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the ZED file in its original format (without conversion to UZED file). Such a solution will be difficult to implement, but it certainly will give the best result.
