- About 18 minutes
- Safe file activity
- 4-question check
Learning Objectives
What you will learn
By the end of this lesson, you will be able to:
- Explain the difference between a file attachment, a Library file and a Project source.
- Upload a suitable file and give ChatGPT a focused instruction for it.
- Find, filter, reuse and download saved files from Library where available.
- Check important answers against the original file instead of assuming they are correct.
- Delete a Library file independently from its original conversation.
- Apply basic privacy checks before uploading or sharing file-based work.
Library Guide
Your reusable file collection
On supported accounts, files you upload to or create in ChatGPT are saved in Library so you can find and reuse them later. Generated images continue to appear in the Images area.
Availability can vary
Library is currently available across several individual plans and is rolling out to some managed workspaces. If it is not in your sidebar, you can still attach supported files directly to a chat where file uploads are available.
Common File Types
Choose a file ChatGPT can work with
ChatGPT supports common documents, spreadsheets, presentations, text files and images. Exact features and limits depend on your plan, file and tool.
PDF documents
Ask for a summary, headings, comparison, key facts or a list of actions.
Word and text files
Review structure, rewrite sections, extract information or create a checklist.
Spreadsheets and CSV
Clean data, explain patterns, calculate results or produce a chart.
Presentations
Summarise slides, improve the flow or create speaker notes and questions.
Images
Describe visible content, read suitable text, compare designs or discuss a photograph.
Plain text and code
Organise notes, explain code, find inconsistencies or convert content into another format.
Do not rely on file extension alone
A supported extension does not guarantee perfect extraction. Scanned PDFs, unusual layouts, damaged files, small text and image-heavy pages may need extra checking or optical character recognition.
Step-by-Step
Upload, instruct and verify
A good result depends on both the file and the task you give ChatGPT.
- Choose a non-sensitive practice file you understand.
- Open a chat or the relevant Project.
- Select the attachment/add control and choose the file, or drag it into the chat where supported.
- Wait for the upload to finish before sending your instruction.
- State the task, audience, required format and any boundaries.
- Ask ChatGPT to identify which parts of the file support its answer.
- Compare important claims, calculations and quotations with the original.
- Download the result if useful, then review your Library and storage.
Practical Uses
Turn files into useful work
Summarise
Extract the main message, decisions, actions and questions from a long document.
Compare
Compare two documents, product lists, proposals or versions against clear criteria.
Analyse
Explore spreadsheet patterns, totals, outliers and possible explanations.
Rewrite
Adapt supplied content for a different audience, tone, format or reading level.
Question
Ask focused questions and request evidence from specific pages, headings or rows.
Build
Create a draft report, checklist, lesson, presentation outline or action plan from the source.
Know Where It Lives
Chat attachment, Library or Project source?
| Place | Best used for | Important point |
|---|---|---|
| Chat attachment | A file needed for the current conversation. | On supported Library accounts, ordinary uploaded files are saved for later reuse. |
| Library | Browsing, searching, filtering, reusing, downloading and deleting saved files. | Deleting the original chat does not delete its saved Library file. |
| Project source | A reference file that should support several chats in the same Project. | Project file limits vary by plan; removing a shared Project file affects members. |
| Temporary Chat file | Short-lived work that should not appear in chat history or Library. | Files uploaded in Temporary Chat are not saved to your account or Library. |
Deleting the chat is not enough
If the file is saved in Library, delete it from Library when you no longer want it stored. If Recently deleted is available, it may remain recoverable there until permanently removed or deleted forever.
Practical Activity
Complete the safe file workflow
Use a harmless practice document with no private details. Tick each step as you finish it; progress is saved in this browser.
Safety and Accuracy
Pause before uploading
Remove private information
Delete unnecessary names, addresses, account details, health information, passwords and confidential business material.
Respect ownership
Only upload material you are allowed to use. Check copyright, client agreements, workplace policies and consent.
Check the extraction
Ask ChatGPT what it could not read. Scans, tables, diagrams and complex formatting may be interpreted incorrectly.
Verify every important result
Confirm numbers, quotations, dates, names and decisions against the source before publishing or acting.
Review Data Controls
Understand your “Improve the model for everyone” setting and any additional rules for a managed workspace.
Manage stored copies
Review Library and Settings → Storage regularly. Remove old files from every place where they remain stored.
Knowledge Check
Check your understanding
Select one answer for each question.
