How can delete pending downloads?

[AC Question]

Delete those pending

A Cache Partition wipe might do it.

Airplane mode will stop the download cold.

Then see if you can delete the download from /Downloads. If you can (I've never tried it, I let it finish, then delete it), it won't "rewind" on most servers, it'll just give you a failure notice which you can tap OK on and forget.
