Auto move image folder does not work with ./assets/${filename}

[mekrina]

Description

Typora's Auto move image folder works when the custom image folder is configured as:

${filename}.assets

For example, renaming foo.md to bar.md also renames foo.assets/ to bar.assets/ and updates the image references.

However, the same behavior does not work when ${filename} is a subdirectory of a shared assets folder:

./assets/${filename}

Steps to reproduce

1. Open Preferences → Image.

2. Set Copy image to custom folder to:

   ./assets/${filename}
   

3. Create this structure:

   foo.md
   assets/
     foo/
       image.png
   

4. Add this image reference to foo.md:

   ![](./assets/foo/image.png)

5. Rename foo.md to bar.md using Typora's file-tree sidebar.

Actual behavior

The Markdown file is renamed, but:

• assets/foo/ is not renamed.
• Typora does not prompt to move the image folder.
• The image reference is not updated.

Expected behavior

Because the configured image path contains ${filename}, Typora should offer to:

foo.md       → bar.md
assets/foo/  → assets/bar/

and update the reference to:

![](./assets/bar/image.png)

Comparison

Using ${filename}.assets works as expected, while ./assets/${filename} does not.

Could Typora support filename-linked image directories nested inside a shared assets directory, or document this limitation?
