Currently (1.7), limewire is able to resume a download only if name and size of the file are the same, even from a different host. However, people name their files the way they want, add little comments etc. Thus, it should be possible for the user to force limewire to accept a differently named file to resume downloading if it has the exact same file size as the original file.

Yeah, it would be great for downloading of BIG files (for resuming). I would see it like message box "You have been downloading a file of the same size but different name, do you want to resume the download with the old file name?"

You can!!!!

Go to your incomplete folder and just rename the file to match the one you want to download. Just don't mess with the T##### stuff, 'cause that's the filesize info.

I've done this, it works.

Along the same lines...
The "DownLoad ALL" does not work well.

I am trying to download the movie K-PAX right now with 1.7c.
I search and 100 duplicate files come up, but when I DownLoad ALL - Limewire picks one - tries to download - and if it fails - I'm out of luck.

On these BIG files and using previous version of Limewire (ie. 1.3/1.4), you could actually download multiple copies of the same file with the same name.
If multiple copies started to download - then I would kill the slower ones. If you ended up completing multiples - then they would overwrite one another (so what).

Why not allow us to download multiples and eliminate that annoying message ("You are already downloading file xxx.xx").
Or at least don't pop that message up until it is actually starts downloading (not just connecting to ip address).
