Adding txt files to Vector Database

Dear Retool and community,

I have a lot of small .txt files, which I want to insert into a vector database.

It is not possible to upload them all, so I simply concat them into one big .txt document, which I want to insert.

The problem is, that this big file far exceeds the character limit of the open text field, and Retool does not accept txt files directly.

Is is possible to create a vector based on these .txt files in Retool? It consists of ~11,000 files and ~80,000,000 characters in total.
