file system – Resuming multiple downloads in Chrome

Many sites give all their files the same name. When downloading multiple files like this, Chrome helpfully adds a (1), (2), etc. to the filename. However, if something interrupts the download, such as a full memory or a connection reset, I find that Chrome often refuses to resume the download, on the grounds that “file already exists.” Typically these are incomplete files and are useless if the download can not be resumed.

Is there any way to get Chrome to finish the downloads in these circumstances?
