Do you really not find a backup-file like #filename.dxf, as perepujal suggested? You must have deleted it then, as they are automatically created. You can just try to open it as it is, not really necessary to rename it.
There is also an other type of backup file: filename.dxf~, which I think can often be found after a crash. Remove the ~ and it can be opened.
