[Orgmode] Adding path and file name into file links

[Graham Smith]

When adding a file link, is there some way of searching for the file you want to add while in the file link and then inserting the path and file name of the found file rather than having to type the whole thing in. 

Or alternatively, can you search for the file with dired and then copy and paste the path from dired into the file link. 

Thanks,

Graham
