`virtual' files

Sometimes I'm downloading big开发者_运维技巧 files which have been split into chunks, say, a 1GByte file into ten chunks with 100MByte each.  Currently, I have to concatenate all files into a new file to be able to access it as a whole.  I now wonder whether it is possible to group these chunks into a virtual file (similar to virtual file systems), avoiding this copying.  BTW, I'm using a GNU/Linux box.

You could use FUSE to make something like this. But it probably isn't worth it, because:

1. It would be fairly complex to handle the various split schemes programmatically without false positives.
2. It's easy to do manually, and only has to be done once per file.
3. With a good file transfer protocol (e.g. HTTP or BitTorrent), there's no need to split the files to begin with.
