The bit your OS hides.
Files carry more than their contents. Windows hangs alternate data streams off them; macOS hangs extended attributes. This add-on lists them, shows what is in them, and lets you edit or remove one on purpose rather than by accident.
Ships — you switch it on
On a normal Tuesday
See the streams on a Windows file.
Listed, named, with their size.
See the extended attributes on a Mac one.
Same list, same place, different operating system.
Change one deliberately.
Editing prefills the current value, binary content is read-only, and removing one asks twice — a stream has no Trash to fall back to.
How you come by it
An add-on is not sold on its own — a bundle is, and holding the same add-on through two bundles is never charged twice. See the bundles.
In the app, off until you move the slider
A fresh install hides anything below the default bar on this add-on’s Minimum readiness slider in Settings › Features. These are in the app today.
- Both plugins. NTFS streams is InTesting and macOS extended attributes is Experimental, so a fresh install shows neither until you move the Platform Minimum readiness slider in Settings › Features.
- The Extended Details view and the attribute editor it opens are shell features and are on by default; what this add-on adds is the per-platform reading and writing behind them.
Nothing announced
Platform is part of the file manager.
Download File Manager, then pick the bundle that grants it.
