@ccat3z This would allow you to create an extension like com.wps.Office.MUI.zh_CN, which, once installed, will be mounted and symlinked at /app/extra/wps-office/office6/mui/zh_CN. Is this what you needed?

[ccat3z]

It works. Thank you!

com.wps.Office/apply_extra.sh

Line 43 in cc7f405

ln -sr "/app/share/wps-office/office6/$target/$lang" "wps-office/office6/$target/$lang"

Maybe it's better to link to /app/share/wps-office/office6/$target/$lang/extra or somewhere? It seems that only the extra folder is writable at the apply_extra stage. I am not familiar with flatpak-builder. I'm sorry if I misunderstood.

[gasinvein]

If you need extra-data in extension, you can put payload in extra/ directory, and create a symlink for each file in it from its parent directory, e.g. zh_CN.png -> extra/zh_CN.png

[ccat3z]

All right.

[gasinvein]

On the other hand, symlinking each file might be tricky. Probably we should use a subdir indeed, so only it would need to be symlinked to extra.

@ccat3z Ok, added data subdir. It can be a symlink to extra in case of non-redistributable langpack, or to . otherwise.
