The Attachment Manager plugin for Obsidian helps users manage attachment folders efficiently by automatically binding folder names to note names. It simplifies tasks such as renaming folders and attachment files, deleting unnecessary folders, and organizing attachments by downloading remote images directly to the attachment folder. Additionally, it allows for hiding and showing attachment folders and automatically renaming pasted images. This plugin ensures seamless organization of attachments, reducing manual file management and offering a smoother workflow for users with multiple media files in their notes.
