Are you sure these files are corrupted, or you can simply not read them with your media player?
Note for example that Windows Media Player cannot read all qualities of MP3 files. Other software players (Real Player, Apple iTunes/QuickTime, Netscape WinAmp...) or mobile players (iPod, Creative, ...) or DVD top-box players are less limited and recognize more encoding options, including support for AAC (the Sony format supported in MPEG4 and used internally in the audio stream of many musical video DVDs).
One thing that makes some files unreadable by some media plyers is the presence of ID3v2 tags.
Note that the basic player integrated in LimeWire (not the greatest one but at least you can check that a file is readable, even if you'll get better performance and audio quality with another player) now can read MP3 files with embedded ID3v2 tags.
But it's true that some people have downloaded corrupted files, and left them in their share folders, instead of deleting them. If you download from them, you'll get the same corrupted files they have, and LimeWire will not complain about file corruption because it won't inspect the actual content of files downloaded, but will only check that the downloaded data matches its advertized size and numeric fingerprint sent in QueryHits (the filename is not relevant) |
