BOOTH Bulk Import tool

A Chrome extension that registers everything you bought, were gifted or downloaded for free on BOOTH to your Yorimichi Closet owned list, all at once.

If you have a lot of purchases, you can also register only the details such as product names and images — no files — into BOOTH Library Manager (a Windows app that keeps everything you bought on BOOTH in one place) and use it as a list of what you own. You download each file only when you actually need it, so it does not eat up your disk space.

Installation

The full package (zip) contains the Chrome extension, an app that registers your list into BOOTH Library Manager (.exe) and instructions. Extract it and follow the included "Read me first" text file.

Download the full package (about 8 MB)

Extract the zip (keep the folder it creates).
Open chrome://extensions and turn on Developer mode.
Choose "Load unpacked" → select the extracted booth-importer-extension folder.

If you only want the extension, there is also extension only (zip).

How to use

1. Issue a token and paste it in
From "Connections and settings" on My Page, issue a token (a password-like string that connects the extension to Yorimichi) and paste it into the extension's settings.
Open connections and settings →
2. Read your BOOTH purchase history
While signed in to BOOTH, press "Scan BOOTH library". accounts.booth.pm/library opens automatically and every page of purchases, gifts and free downloads is read.
3-A. Send to Yorimichi (recommended, easy)
Press "Send to Yorimichi" and everything you own is registered to your owned list at once. Items not yet on Yorimichi appear the next day.
View owned items →
3-B. Register the list only, without downloading files (recommended for large libraries)
Register only the details such as product names and images — no files — into BOOTH Library Manager and use it as a list of what you own (your disk space is untouched).
1. In the extension, press "Export for catalog" and save yorimichi-blm-catalog.json.
2. Quit BOOTH Library Manager and drag & drop that json onto the included yorimichi-blm-catalog.exe.
3. Start BOOTH Library Manager and every item is listed. Download just the files you want, one at a time, via "product page → other download methods → BOOTH Library Manager".
* Items registered this way can also be imported as owned from the Unity Integration Tool.
3-C. Download all the files at once (optional)
Only if you want every file right now. With BOOTH Library Manager running, press "Bulk download with BLM (files)" and the files are downloaded one after another in a dedicated tab. A large library takes a lot of time and space, so 3-B is recommended if you have many purchases.

Note on 3-C (bulk download): BOOTH Library Manager only accepts 10 at a time. If you have many large avatars, lower the "wave size" and raise the "wait" (for example 4 items / 180 seconds). BOOTH Library Manager comes to the front on each import; that is expected. If you have many purchases, 3-B without downloading files is more comfortable.

Only BOOTH product IDs are sent to the server (files, purchase amounts and personal information are not). The token is stored only in your browser, and your owned list is completely private. The downloads in 3-B and 3-C happen entirely on your own PC.

Requirements

Google Chrome / Microsoft Edge
A Yorimichi Closet account (Discord sign-in)
BOOTH Library Manager (Windows) if you use 3-B or 3-C

If you use Unity, the Unity Integration Tool is also available.
