Why we like it

Open With earns its place for folding a multi-step version switch into a single File menu action, then layering addon comparison and crash detection on top of the transfer.

What is Open With?

Open With adds a single entry to Blender's File menu for moving a .blend file between the Blender versions installed on your machine. Selecting File → Open With opens a dropdown that auto-detects every Blender installation on your system, including custom installations on other drives, so you pick a target version and the file transfers in one click.

Each time you switch, the add-on scans the target version's addon folder and compares it against your enabled addons. Any addon missing in the target appears in a compatibility warning dialog with a Transfer button. After launching the target Blender, Open With watches the process, catches the case where Blender exits before the file finishes loading, and reports why it failed rather than only that it did. For large version gaps, it supports stepping a file down gradually through in-between versions.

A More Versions panel fetches the full list of official Blender releases and daily experimental builds from blender.org. Preferences cover auto-save before switching, backup copies, backup location, crash-detection timeout, and custom installation paths. It runs on Windows and supports Blender 3.0 up to the latest 5.x releases.

Who is Open With best for?

Open With is best for blender artists who keep multiple Blender versions installed and regularly need to open a .blend file in a different version.

How much does Open With cost?

Open With is completely free to download and use.

Frequently asked questions

What Blender versions and operating systems does Open With support?

Open With supports Blender 3.0 and above, all the way up to the latest 5.x releases, and runs on Windows. Its version dropdown auto-detects every Blender installation on your system, and you can point it at custom installations on other drives through a built-in file browser. If you keep several versions side by side, such as an LTS build, a production build, a daily build, or an older release, they can all appear as switch targets. For details on any newer releases, check the developer's page.

How do I install Open With in Blender?

Open With installs like a standard Blender add-on. Download the zip, open Blender and go to Edit → Preferences → Addons, click Install and select the zip file, then enable Open With by ticking its checkbox. Once enabled, it appears in the menu under File → Open With. No configuration is required to get started, though its preferences let you adjust behaviours such as auto-save before switching and backup copies later if you want to. The whole setup follows Blender's usual add-on installation flow.

How does Open With handle switching between very different Blender versions?

Open With supports stepping a file down gradually rather than jumping across a large version gap in one move. Switching directly from, say, Blender 5.0 to 3.0 can lead to crashes, so the add-on lets you move the .blend file through in-between versions to keep it compatible. After launching a target version, it watches the process and, if Blender exits before the file finishes loading, catches that as a crash and reports why it failed rather than only that it did.

Does Open With move my enabled addons to the target Blender version?

Open With scans the target version's addon folder each time you switch and compares it against every addon you currently have enabled. Any addon that is missing in the target version shows up in a compatibility warning dialog with a Transfer button, so you can move it across in one click. This comparison runs automatically as part of the switch, which means you can also treat it as a way to carry your enabled addons between Blender installations.

Is Open With free?

Open With is listed as free here in our catalog. Because licensing and any future changes are set by Flidoh Animations, check the developer's page for the current terms before you download. The add-on also lists documentation among its resources, and a demo video is available if you want to see more before installing. Installation follows Blender's standard add-on flow through Edit → Preferences → Addons, so there is nothing to configure beyond enabling it.
