PDF files are excellent ways to pass around your documents are they can be viewed on any computer. All sorts of computers: Windows, Linux, Mac, even PDAs and mobile phones.
You can also make your PDFs more secure by putting a password on them. Before the PDF can be opened, the person who wants to read the file needs to enter a password.
Which is fine until the moment you need to open a PDF that's password protected but you've stored the password in a "safe" place. Maybe the email is at home and you can't access that PC from wherever you are. Or maybe the email with the password has been deleted. Or maybe your view was that you always use one of a handful of passwords so you'd not have a problem remembering it. It could be the PDF was protected by someone who no longer works for your company.
Ebooks you've just bought often have a password to "protect" them (I've no idea why they do this). For some reason, the product owner thinks that because you've just paid them good money, you're now going to rip them off. Personally I think that treating customers like thieves will make them more open to sharing files. After that, I re-name the PDF file so that it includes the password. That way it's easy to find the password and I don't have to hunt through all my emails to find it. I haven't always done this and some files have had to stay locked.
Often you only realize a password has been lost at the last minute. So you need to retrieve the password quickly.
There are several ways to get around this problem.
You can give up and hope that there's nothing of importance in the file.
If you've got time on your hands, you can start to enter all your "favorite" password combinations. Usually in the vain hope that you'll quickly find the password you used to protect the file.
You can download an inexpensive PDF password recovery program that will do all the typing for you and will retrieve the PDF password you've lost in just a few minutes.
