Links between org files

Question

Say I have two org files, file1.org and file2.org on disk (let's assume they are in the same directory). How can create a link on file1.org to file2.org?

Once I have the link on file1.org, let's assume I have cursor (point) sitting on that link. How can I tell Emacs to show me the corresponding file?

Finally, what if I want to create a link to a specific item of file2.org ?

Answer 1

Use the C-c C-l shortcut to create link and use the syntax

file:./file2.org

and use C-c C-o with cursor on link to visit that link.

To link to a specific item, use

     file:projects.org::*task title            heading search in Org file

the doc: http://orgmode.org/org.html#External-links

you can even search for words:

file:projects.org::some words

Answer 2

I like to use org-id-copy. It's kind of a precision instrument compared to the other methods that give you troubles when there are many candidates.

After the call, current heading will have ID set in its property drawer. The ID looks like 5d76eafc-94f6-47b1-ae4c-a7e917986fd1 and it's in your kill ring now. You can insert with C-c C-l to make it look like

[[id:5d76eafc-94f6-47b1-ae4c-a7e917986fd1][link]]

You can see a sample usage within one file at https://gist.github.com/abo-abo/6040382 , but it also works across multiple files.
