FileRun can open office documents in an editor that runs in the browser, so several people can work on the same file at once. The document stays in FileRun; the editor only borrows it while it is open.
Five editors can do this, and they fall into two groups.
These are separate servers that you run on your own infrastructure. FileRun talks to them over the network, using the WOPI protocol, and the documents never leave your systems.
These need nothing installed, but the provider's servers fetch the document from your FileRun installation, so it has to be reachable from the Internet.
All of them are configured in the control panel, under Files → Plugins. Select the plugin
and click Edit.
To make one of them the editor that opens when a user double-clicks an office document, set it as
the default under Files → Plugins → Defaults. Otherwise it is offered in the
Open with.. menu.
Other ways of previewing and editing documents, including the ones that do not edit together, are listed on File preview options.
Collabora Online, ONLYOFFICE Docs and LibreOffice Online share the same two settings.
The address of the editor server, for example http://localhost:9980.
The protocol has to match. If FileRun is served over
https://, the editor URL must behttps://as well; if FileRun runs on plainhttp://, so must the editor. FileRun refuses a URL whose protocol differs from its own, because editing would not work.
When you save a new URL, FileRun contacts the editor and reads its WOPI discovery document. It
confirms this with Document editing service successfully validated!. If it cannot reach the
editor, or the answer is not a WOPI service, the settings are refused and nothing is saved — so a
saved setting is one that was proven to work.
Leave this on. You can turn it off when the editor server is inside your own network and uses a certificate that your FileRun server does not trust.
The editor is loaded by the person's browser, not only by the FileRun server. The address you
configure has to be reachable from both. An address such as http://localhost:9980 works only
when FileRun and the editor run on the same machine as the browser, which is normally true just
while testing.
For everyday use, publish the editor under a hostname your users can reach, with a certificate that matches, and use that hostname in the setting.
