Frequently Asked Questions
What is an OPML file?
OPML stands for Outline Processor Markup Language. It's an XML-based format used to share and transfer lists of RSS/Atom feeds, podcast subscriptions, and hierarchical outlines between apps. Most feed readers and podcast managers can export and import OPML files.
Which apps export OPML files?
Common apps that export OPML include Feedly, Inoreader, NewsBlur, The Old Reader, Overcast, Pocket Casts, Reeder, NetNewsWire, and most other RSS readers and podcast managers.
Is my OPML file uploaded to a server?
No. Flipper File processes your OPML file entirely in your browser using JavaScript. Your file never leaves your computer and is never sent to any server.
What's the difference between an OPML file and an RSS feed?
An RSS feed is a live data stream from a single website or podcast. An OPML file is like a bookmark list — it contains the URLs of many RSS feeds so you can move your whole subscription list from one app to another.
Why does my OPML file show as XML?
OPML is a subset of XML, so many apps save OPML files with a .xml extension. Flipper File handles both .opml and .xml files as long as they follow the OPML structure.
What does "nested" OPML mean?
OPML files can have folders (called outlines) inside other folders. This mirrors how many RSS readers let you organize feeds into categories. The viewer renders these nested structures as collapsible groups.
Can I view a podcast OPML file?
Yes. Podcast OPML files follow the same structure as RSS OPML files. The viewer will display each podcast with its title and feed URL.
What should I do if my file doesn't load?
Make sure the file has a .opml or .xml extension and that it contains valid OPML markup. If the file was exported from an unusual app, it may have minor formatting issues. You can try opening it in a text editor to confirm it starts with <opml version=.
