Describe your proposal

If you specify the name of the directory, when executing the GHA, keep that directory intact.

Describe the solution you'd like

I would like to be able to keep contents of a directory even after pushing files to the root.

Describe alternatives you've considered

I do not know the details of your demand. But the option keep_files seems worth reading.

This wouldnt replace existing file, which I would still need.
Let me try to explain in more details. The destination dir is root so on every run of the GHA, everything is the root would be removed. I do want all the single files to be removed and recreated (even if some of them are named the same, maybe its content is different). But if there is an option like exclude_dir: name_of_directory it would keep this directory intact.

This would also be very useful when using pr-previews https://github.com/rossjrw/pr-preview-action

Every time a new build is deployed it wipes the pr-preview directory so all active previews are killed.

This issue and #771 are very similar.

A related use-case is when static content refer to specific versions of published software. Say we have content for v1, v2 and main/latest.

It would be really cool to be able to have the action publish on tag push to docs/{tag}/index.html, and merge to main to docs/latest/index.html

This requires "overwriting" latest, but not any other content. In other words, a whitelist or regex expression declaring what to delete (keep_files is essentially a special case of this where true <> "*"

I switched to JamesIves/github-pages-deploy-action@v4. It has the following options

force: false
clean: true
clean-exclude: pr-preview/

which works perfectly for my use case.

I just realized that destination_dir and keep_files: false is enough for versioning since we can just have one dir per version and have a "latest" or "main" for the latest.
