You could find a kid to help you. But if you can't locate a crumb cruncher, here's how you do it.
First, make sure the file is in PDF format. If the file doesn't have a .pdf at the end or the Adobe icon representing the file, check with your publisher. If you can't get a copy from your publisher, you can convert a .doc, .epub, .mobi, or other format into .pdf by using a free conversion program, such as Calibre (http://calibre-ebook.com/). Calibre has been used successfully by many people and it's pretty easy to use. If you convert your file yourself, let us know so we'll be aware of any issues that may arise from the conversion.
Now that you have a pdf file, open it. Select "save as"; a dialog box opens with a suggested filename. Your operating system won't let you just save it with the same name, because it wants a different one. In the suggested filename, type in the category code (letter-number for most categories, available in the category descriptions in the rules), add a hyphen, then type in the full title of your work. Make sure you choose the file type as PDF. Click on "Save". It should save a copy of your book under that name. There will now be two copies of the book: one with the original name and one with the new name.
Simpler method: Open your file manager. Find the PDF file. Right click and select Rename. Type in the correct name and return. The file will be renamed.
Note: The file may move after you rename it this way. Your file manager may resort the files to put the newly renamed file where is should be, based on how your file manager settings are set.
Pay attention to the category code. We have made some changes to the codes, as well as to the categories. For instance, make sure PO, CH are all letters. Make sure F01, R07, etc., are "F-zero-one" or "R-zero-seven" - with no hyphens between letters and numbers. Your book won't be put in the correct category if this isn't correct.
