You can now go back to a file you already used in ChatGPT and keep working from there instead of uploading it again. That makes follow-up questions faster when the PDF, spreadsheet, deck, or notes are already sitting in your account.
The first good use is simple: reopen yesterday's document and ask one sharper question. You save the setup time and get straight to the part you actually care about.
What changed
OpenAI says files you upload to or create in ChatGPT are now saved in a Library so you can find and reuse them later. The feature is available across Free, Go, Plus, Pro, and Business accounts.
OpenAI also expanded the file library rollout to Free and Go users on May 14, along with storage management and recent-file access from the composer.
What this means in plain English
If you use ChatGPT for document work, the annoying part is often the second pass. You already asked for the summary yesterday, but today you need the client risks, the missing numbers, or the three slides that should change before the meeting.
Library turns that second pass into a shorter job. Pull the file back in, ask the narrower question, and keep moving.
This is especially useful for proposals, meeting notes, decks, budgets, policy PDFs, and messy spreadsheets you revisit more than once.
A good first request
Try a follow-up question on a file you already uploaded, such as:
Open the proposal I used yesterday. Give me the three parts a busy client will read first, then flag anything that sounds unclear or too long.
That keeps the task small and easy to verify against the original file.
How to use it
- Open ChatGPT on the web and go to Library from the sidebar.
- Pick a file you already uploaded, or add it from Library through the attachment menu in a new chat.
- Ask one narrow follow-up question instead of requesting a full summary again.
- Check the answer against the source before you reuse it in an email, slide, or spreadsheet.
- Delete old files you do not want hanging around. Files from Temporary Chat are not saved to Library.
What to do today
- Find one file you already uploaded in the last week.
- Reopen it from Library instead of uploading it again.
- Ask one question that would normally make you scroll through the file by hand.
- If the answer helps, save the exact prompt in your notes so you can reuse it on the next file.
