The site looks dated. There appears to be little or no Support.
I’m comparing Dabble to PA. Dabble is slam dunk easy but limited. PA is not the least bit easy but has potentially useful features I’d like. I have four false starts and can’t see how to delete projects and documents to start over. I won’t try much longer.

Hi there,
On Windows, PA will initially store new projects and documents in the default folder (C:/User/Username/Documents/Papyrus Author Documents) unless you specified a different folder via ‘Save as…’
Just delete any projects you don’t need anymore in the Explorer.
I’m on a Mac and Safari.
I don’t see the Explorer. I have Navigator and Organizer. I see no way to delete projects to start over.
Adding chapters: The tutorial says to drag a chapter to the PA Icon. I drag over a docx., the cell darkens, but nothing gets imported.
I want to evaluate the grammar and style tools. Do I have to upgrade to do this? I’m on the introductory version now.
Thanks,
Will
On a Mac this would be your Finder. 
Look for files with the ending *.pap or *.papproject
I am on Windows, so I don’t know how things work on a Mac. But I’m sure @Sam or someone else will be able to help. If all else fails, you can always contact support [at] papyrusauthor [dot] com.
Hi! 
When you drag and drop a .docx to Papyrus Author, it should turn into a Papyrus Author file automatically. 
If this isn’t happening, there might be a hiccup with the file you’re bringing in, or Papyrus Author doesn’t have access rights to change files on your computer.
Have you tried using a different .docx file? If it’s an issue with just this one file, feel free to send it to me in a private message, and I’ll take a look. 
Apple has changed their access policies a bit, and depending on the settings of your computer, you might need to add the rights for Papyrus Author to edit and save files on your computer. Here’s Apple’s quick explanation and guide on how to do that: Controlling app access to files in macOS - Apple Support
You can activate The Style Analysis with the feather icon on the bottom toolbar, and the Readability Check with the eye icon next to the Style Analysis. 
Thanks @joey 
Yep–the projects should be in the “Documents” folder under “Papyrus Author Documents” on both macOS and Windows.
If you’ve saved them elsewhere, you can search for them with Spotlight: Search with Spotlight
Let us know! 
Is there any way in which the default folder can be changed? I have no use for the existing one.
I think a default catch-all location that has all your stuff (even that one quick idea you forgot to name and save 
) is super valuable—I’ve never thought of changing it! 
Do you have some cool workflow where you need to fire up a lot of new documents? Then I can see how setting the default could come in handy.
There’s an option to change the save location when you start a project or when you save an unnamed document, but right now, the preset location (Papyrus Author Documents) can’t be changed.
There’s also a tech reason for this: “Documents” is the safest place for Papyrus Author to save things. Depending on individual computers’ settings, other locations might be blocked or restricted, which could cause problems when trying to save elsewhere.
I try not to store any data on Drive C: which keeps it small and easy to restore from a sector-by-sector backup. It is impossible to measure the total size of all my .pap files but it must be quite large. The contents of my Papyrus Docs folder totals 158GB, but that includes other things such as images, of course.
I think it would be reasonable to assume that if the user selected a place for a Papyrus Author Documents, that it would be as accessible as a folder on C:.
It particulalry irks me that if I open a .pav file from one location, Papyrus does not offer to save the .pap file to the same place.
Thanks Sam.
What’s the next thing after a super user? That’s some huge numbers! 
(For reference, I think 1000 US letter pages of just text take about 10MB )
That’s a monstrous amount to keep backups of as well!
I think computers’ security features want either administrator access, whitelisted destination, a separately set “Trusted App” status, or a mix of these to give write rights to apps consistently for protected destinations.
So a lot that can go wrong, and it’s a bummer to fight with Windows Defender, when all you want to do is write. 
As I understand it, this is a malware (for example, an encryption attack) protection measure, where an untrusted app can’t write into protected locations. 
Yes, most are not .pap files, of course, but I cannot estimate what percentage are. But isn’t it wonderful that terabyte drives are now available. I started with floppies, and thought life couldn’t get any better when I bought a 40MB hard drive for my Atari ST (on which I was running Papyrus).
