I am afraid that we do not have such API Method exposed that can help you programatically remove the file entry from the Upload widget.
The only possible way I can think of is to use the internal method for this job.
up = $(
allLiElementsToBeRemoved = up.wrapper.find(
Of course instead of removing all the files you can pick just these that you need.
Once again keep in mind that using internal methods is not something that we recommend and it can potentially break the logic for future releases.
I hope this helps.
