obsidian-file-path-to-uri VS obsidian-binary-file-manager-plugin

I can use obsidian-file-path-to-uri to convert them easily once they are in Obsidian but it's a manual process that has to be repeated 1800 times.

Install File Path to URI plugin

I'm not sure if this is the correct solution to your answer but there is a way to put images without Obsidian making a duplicate note of it inside the vault. You need to install the community plugin called File Path to URI. Then you need to follow these steps.

I found this. May that help? https://github.com/MichalBures/obsidian-file-path-to-uri

And ideally, i'd like to merge all these attachments into one attachment group or so. I don't really want to create new folder and load it all there as it is still a folder. Do you guys have better idea or 3rd party plugin to fix this? i found file path to URI but it doesn't solve my problem as i directly screenshot something and load it into the Obsidian without physically saving it onto the drive.

This developer animation shows that in action. Maybe you could do the same thing with a PDF - I haven't tried it. However, in the Settings of the plugin, you can choose which files you want the plugin to monitor. PDF is a choice so maybe it already creates companion files for PDFs. If so, you should be able to treat a PDF like a regular note. And remember that a companion MD file will exist for each PDF.

The Binary File Manager plugin can be helpful for integrating images into your knowledge base. It helps you treat images like notes.

You might also find a use for the "Binary File Manager Plugin" .. here's a description

I don't know if the Binary File Manager plugin will help but it lets you treat an image like a note you can tag and add metadata to. It works with new images you add to the vault. I don't know if it can work with existing images. It works by creating a companion markdown note for each image that goes into the vault.

The Binary File Manager plugin lets us treat an image like a regular note that we can tag, search for and link. (info here)

The Binary File Manager plugin documentation cites benefits of that happening. And that plugin gives you additional options for managing the way that happens.

This Obsidian plugin explains this in terms of being able to catalog images instead of audio files. But the principles are the same.

Check out the Binary File Manager plugin. It will automatically create a Metadata note for your binary files.
