Is there a straightforward way to deal with edge pieces? about torrent HOT 4 CLOSED

Not currently. It's definitely an interesting case. On most filesystems, those edge pieces will be stored efficiently, although appear confusingly in the filesystem. There's not a simple way to handle this case, except perhaps to always store partial files with a special marker in their name. What do you think of that? Say files a, b, and c in a torrent, and you request b. If there are edge pieces overlapping with a and c, you might see in your directory upon completing b, {a.part, b, c.part}.

Sounds good. But then there should be an efficient way to merge and grow pieces. Especially when the file system nearing its capacity or heavily fragmented.

Assuming the filesystem in use supports sparse files (most modern ones do), the merging isn't necessary, and growing is automatic with the existing mmap and file data backends. In the case that the filesystem doesn't support sparse, you can use the piece backend, and access the files through Torrent.NewReader as required, to get maximum space efficiency.

Ok. Thanks!
