Asking Questions About Files
Once a file is uploaded, just ask about it naturally:Tips for Best Results
Name files clearly
q4-2025-financial-projections.pdf is better than doc_final_v3.pdf. The filename gives AIs context.
Upload relevant files only
Don’t dump everything. Upload files that are directly relevant to this project’s purpose. Quality over quantity.Mention the file
While AIs can find file content automatically, explicitly mentioning “based on the uploaded report” helps them focus on the right source.Update when needed
If a file has a new version, upload the updated version. Old versions can be removed.Consider file size
Large files work, but the most relevant sections are prioritized. If you have a 200-page document, the AIs focus on the parts most relevant to your question.What Files Can’t Do
- Files don’t replace custom instructions (use instructions for persistent rules)
- Files aren’t shared across projects (each project has its own files)
- Files can’t be edited within Suprmind (upload new versions instead)
- Very large files may have partial indexing (most relevant sections prioritized)
