@jgrantr is there a better way to do this? I just need a promise that I'll resolve somewhere else

No. If you don't want everything in the block, what you have done here is what I've done in other places. May want to give it a more descriptive name (like, what does the promise represent) so it's clear what it is used for, but the general approach looks good.

Rename these so the are more readable

| purgeSize += file.size; | ||
| logger.debug("Would delete:", file.fullpath, eidTimestamp, startEidTimestamp, endEidTimestamp, size, maxStorage, eidTimestamp < startEidTimestamp, eidTimestamp > endEidTimestamp && size > maxStorage); |

@czirker This will fix us not having an S3 file for the given index, right?
