Our law office is trying to go paperless, so when we get correspondence in the mail, it is scanned into a common folder where it gets renamed and then moved to the appropriate client folder. I don't understand how other software developers have figured out a way to allow renaming or deleting a PDF file while previewing it, and Adobe and Microsoft can't put their tiny brains together and figure it out, but still manage to charge an arm and a leg for their products. This is an issue that has been present for YEARS, and it's still not fixed. Sorry, but the 'don't use the preview pane,' 'use another file manager,' or 'don't ever plan on recovering your deleted file' aren't viable work-arounds for as much as we pay for this product.
