Yes, the upload files are saved to disk, then load it by filer parser

GenAIComps/comps/dataprep/src/integrations/redis.py

Line 395 in 589587a

await save_content_to_local_disk(save_path, file)

Keep files in memory for this step.
But list files and other need to be changed and evaluted.

I'll propose a PR later to fix this following the doc/docx file convention, after I fixed #1324
