Delete File (Unpin)

Delete a file by CID

Unpin All Files

If you find yourself in a place where you need to unpin a lot of files or perhaps all your files, you can use a script like this to create an array of CIDs and unpin them one by one. The example below uses the pinList queries to target all pinned files and return 1000 for each request. This could easily be done with a different query to target different files, please check out the listing files doc for more info.
