How to Back Up Custom GPT Knowledge Files

Keep originals of every knowledge file and decide how they will be loaded after migration.

The editor does not give you a one-click download of everything you uploaded, so rely on your original source files.

Steps

  1. Open the GPT editor and list every file under Knowledge.
  2. Find each original on your computer or drive. Note which are outdated.
  3. Name and version them in one folder.
  4. Type the file names into the checker so they appear in your bundle checklist.

Plan the reload

New platforms may limit file count, size, or format. Convert odd formats to PDF, DOCX or plain text and split very large files by topic.
