Short answer: You can upload up to 100 files or 100 MB at a time, whichever comes first.
Full explanation:
When uploading documents to an index, AskTuring allows a maximum of 100 files or a total of 100 MB in one upload batch, whichever limit is reached first.
If you need to upload more than this, you can simply perform additional uploads until all your files are added.
Tips:
Larger batches may take longer to process, especially for complex files.
Consider organizing your uploads in logical groups to make managing them easier later.
