Where are my files kept?

On your own device, inside this browser. Nothing is uploaded to SparkPrep. That also means clearing your browser data deletes them, so use Download a backup now and then.

How should an author organize book files?

Keep one folder for the current manuscript, one for every older draft and edit, one for notes, one for cover files, and one each for research, marketing and paperwork like ISBNs and contracts. Put the date or a version number in every draft's name so you never send the wrong file to the printer.

File Manager for Authors

Q: Is the SparkPrep file manager free?

Yes. It is free, with no sign-up and no limit on folders or notes. The only limit is the storage your own browser allows.

Keep your book, every draft, your notes and any other file in one place. Free, no sign-up. Your files stay on your device.

Folders made for writing a book

Every author ends up with the same mess: final.docx, final-2.docx, final-REAL.docx, notes in three apps and cover files nobody can find. This file manager starts you with the folders a book needs:

My Book for the one manuscript you are working on now.
Drafts & Edits for every older version and your editor's markup. Add a file with the same name twice and both are kept, each with its date.
Notes for ideas, characters, timelines and feedback. Write them right here.
Cover Files for your front cover, full wrap, artwork and barcode.
Research, Marketing and Publishing Paperwork (ISBNs, contracts, printer emails).
Other Files for anything else. It takes every kind of file.

Your files stay with you

Files are saved inside this browser on this device. Nothing is sent to SparkPrep, so there's nothing to hack and no account to make. Two things to know: your files won't show up on your other devices, and clearing this browser's data deletes them. Press Download a backup now and then to keep a copy.

Questions

Is it really free?

Yes. No sign-up and no limit on folders or notes. The only limit is the space your browser allows, which on most computers is several gigabytes.

Can I open my files here?

Pictures, PDFs and text files open right on the page. Word files and others download so you can open them in their own app.

What should I do when my book is finished?

Check it before you upload it. KDP and IngramSpark reject books for margins, bleed, fonts, low-resolution pictures and ink. SparkPrep's free audit finds all of them, and SparkPrep can fix them for you.
