I recently ran into an error with a client’s off-site backup using Cloudberry to Backblaze B2 that simply said: file name segment must be no more than 250 bytes

Nice, right? Digging into the logs, I found that it was erroring out on an amazingly long .JS file a user had copied over with a bunch of personal files.

Enter SuperDelete on Github. Download it from the release page or compile it yourself, move it to the problem folder and let it do its magic. Simply run the executable (no installation necessary!) and name the file in question and you’re golden!
