How Do I Use Bankr's File Storage?

Every Bankr wallet comes with its own persistent filesystem. This isn't just a temporary cache; it is a permanent workspace where the agent stores documents it generates for you, files you upload, and the data it needs to remember your preferences.

Accessing Your Files

The easiest way to manage your storage is through the web interface at bankr.bot. Once you're logged in, click the Files panel. From here, you can:

• Upload: Drag and drop files directly into the panel or use the upload button.

• Edit: Click on text-based files (like .md, .txt, .json, or code) to open them in the built-in editor.

• Preview: View images, PDFs, and formatted Markdown files directly in your browser.

• Organize: Browse through folders to see how your agent is organizing its work.

Asking the Agent to Manage Files

You don't always have to click around the interface. You can ask Bankr to handle file operations using natural language. For example, you can ask the agent to download a report from a website or move data between folders.

Try prompts like these:

• "Download my latest transaction statement as a CSV and save it to my root folder."

• "Read the file at /research/notes.md and summarize the key points for me."

• "Create a new folder called 'Invoices' and move all my recent PDFs there."

• "Upload my tax-doc.pdf to the form on this website."

Refer to a file however is natural — a path such as /research/notes.md works anywhere a file ID does, on every file tool.

Asking Questions About a File

Some questions are about a file rather than its contents: how many rows match, what's the total, which entries are over a threshold. Loading a 4 MB CSV into the conversation just to count lines is slow, so the agent can instead run a small read-only pipeline against the file in a sandbox and return only the answer — the file itself never enters the conversation.

• "How many rows in /exports/portfolio-2026-04.csv have a negative pnl?"

• "Count the ERROR lines in /logs/run.log"

• "What's the highest score in /data/candidates.json?"

This is available on every wallet — no Bankr Club subscription needed — and you don't have to ask for it by name; the agent reaches for it when a question is an aggregation rather than a read.

What it can run: jq for JSON and JSONL, plus grep, egrep, fgrep, awk, cut, sort, uniq, wc, head, tail, cat, tr, nl, rev, paste, column, and comm. These can be piped together, but there's no redirection, command chaining, or network access, and the pipeline is strictly read-only — it can never modify the file.

Limits: text files only (not PDFs, images, or archives), up to roughly 5 MB per query; answers are capped at about 8,000 characters; and the pipeline is cut off after 10 seconds. Above the size limit the agent falls back to reading the file in ranges. If you hit the other two, narrow the question — a count or a top-N rather than a dump.

Understanding the File Layout

Bankr uses a specific folder structure to keep your workspace organized. You'll notice a few special directories:

• /.memory/: This is where the agent stores what it knows about you. Editing these files directly can change how the agent behaves or what it remembers.

• /cli/: This folder contains your installed CLI skills and custom tools.

• /apps/: If you use or develop Bankr apps, their code and assets live here (e.g., /apps/my-cool-app/).

Storage Limits and Tiers

Your storage capacity depends on whether you are using a free account or are a member of Bankr Club.

Safety and Restrictions

To keep your environment secure, Bankr blocks certain executable file formats. You cannot upload or store .exe, .sh, .bat, or .com files. However, almost all common document types—including PDFs, images, spreadsheets, and code files—are fully supported.
