GitHub has nice feature that you can attach files to issue comments.
But is there any way to undo attaching unwanted file?
Even if comment is never submitted the file stays there forever, see for example https://user-images.githubusercontent.com/899988/146889867-edb59e9a-5709-4c17-b6d5-b0c863bc5f9e.png
It is even worse with .ods files where randomly generated part is much shorter.
How can I trigger deletion of such accidentally uploaded files if I have link to them?
If you're the uploader of the image, which has an URL in this format https://user-images.githubusercontent.com/123456/123456789-abcdefgh-1234-abcd-1234-1234abcd5678.png, you can now make use of the virtual agent to remove the image: https://support.github.com/?q=remove+image+attachment
Click on the button "Remove uploaded images with our Virtual Agent".
If you're trying to delete an uploaded file with an URL in this format https://github.com/github/linguist/files/1/example.docx, use this link instead: https://support.github.com/?q=remove+file+attachment
The deletion is not instant, but took less than a day.
