Currently this feature is not fixed/fully implemented.
Fixed: All space chars should be changed to %20 in the generated URL string so that it can properly be pasted as escaped HTTP links.
Fully: You can only generate an HTTP URL for a single file. If you have 10,20,100 links you need to create, you cannot just select all of the files at once to create URLs for in the clipboard, you have to do them individually 10,20,100 times based on need.
The features above currently are currently implemented in your competition SmartFTP ('copy http url' function).
