There are many ways to drag and drop things around Obsidian to make the experience smoother:

Drag panes

See dragging panes

Drag sources

• You can drag a file, or multiple files from the file explorer.
• You can drag a file from a search result.
• You can drag a file from backlinks or unlinked references.
• You can drag a file from the starred notes.
• You can drag a file from a link inside the note, in preview mode.

Drop destinations

• You can drop a file on a pane header to open the file there. Hold Alt (or Shift on MacOS) to drop anywhere on the pane.
• You can drop a file on a folder in the file explorer to move the file there.
• You can drop a file into an editor to insert it as a link. The generated link also follows your preferences, such as relative paths, or using markdown links.
• You can drop a file on the starred notes to star it.

Dragging from outside Obsidian

• You can drag any HTML content from the browser into Obsidian to automatically convert them into Markdown
• You can drag and drop any files from your native file explorer to have Obsidian import (make a copy of) those files in your vault's attachment folder and insert them as internal links. Hold Ctrl to create file:/// absolute links to those files instead of importing a copy.

Dropping files outside Obsidian

• This will create an obsidian:// URL in the external application for the Obsidian note that you dragged.
