Computers are tools to create work that you can later publish or share. Saving, editing, and sharing that work depends on the file type!
Before we dive into software, we need to talk about a concept that often gets lost in the world of phone apps and social media:
When you create something on a computer, there are usually two versions of your work:
a working file (used for editing and making changes)
a deliverable file (used for sharing, submitting, or publishing)
Computers and software are tools that help you create work that can later be shared with others. Understanding the difference between these two file types will save you time, frustration, and lost work.
Working: Photoshop .PSD file with layers, adjustments, and notes
Deliverable: Exported .PNG or .JPEG for a website or client
Working: Word .DOCX file with notes, edits, and tracked changes
Deliverable: Exported .PDF for submission, sharing, or printing
Working: Adobe Premiere .PRPROJ project file with all clips, edits, and timelines
Deliverable: Exported .MP4 video ready to upload or share
Working: Audacity or Logic project file with multiple tracks and edits
Deliverable: Exported .MP3 or .WAV ready for distribution
Working: Excel .XLSX file with formulas, raw data, and multiple tabs
Deliverable: Exported .CSV or .PDF report for sharing or submission
Working: PowerPoint .PPTX file with all slides, animations, and notes
Deliverable: Exported .PDF or .MP4 version for sharing or submission
Understanding the difference between working and deliverable files helps you:
Submit the correct file type for assignments
Keep an editable version of your work
Share files that actually open for other people
This distinction applies across all software, not just the tools listed above.
You will use Diagrams.net to create a mind map. Here is how the working vs. deliverable file distinction applies:
Working file: Save your mind map as an XML (.drawio) file. This file keeps all of your structure and allows you to edit your work later.
Deliverable file: Export your mind map as a PNG file. This is the version you will submit, share, or post online.
Saving commits your changes so the program can read and edit them later (working file).
Exporting converts your work into a format that other programs or people can easily use (deliverable file).
If you only save a working file and never export it, others may not be able to view your work. If you only export a deliverable file, you may not be able to edit it later.
Understanding this difference is a core digital literacy skill you will use in every course and most jobs.
