How to Unzip Files in Google Drive (And Streamline Agentic Access)

Identity-based attacks targeting Google Workspace environments rose by 127% year-over-year in 2025, driven largely by malicious OAuth app integrations and credential theft Guardz 2025 Security Report. Connecting third-party zip extraction extensions to a corporate Google Drive exposes organizations to substantial supply chain risks, which is where this guide lives. Unzipping files in Google Drive refers to extracting compressed folder contents, a task that currently requires third-party add-ons or downloading the file locally due to the lack of native Drive tools.

When a team needs to extract files within a shared directory, they often select tools from the Google Workspace Marketplace. The marketplace hosts over 5,000 applications, many of which require extensive API permissions. If a user connects a file extraction utility, they must grant OAuth scopes that allow the app to read and write every file in their account. If the developer account of that utility is compromised, attackers can access session tokens and compromise the directory within 11 days on average Google Cloud Cybersecurity Action Team Threat Horizons Report.

To prevent these security gaps, developers have traditionally chosen from the following alternatives when managing shared file archives:

• Local Desktop Extraction: Downloading the zip archive to a local hard drive, unzipping the folder using operating system utilities, and uploading the files back to the cloud. This method is secure but slow.
• Dedicated Cloud Storage Buckets: Storing archives in isolated S3-compatible cloud storage, which allows programmatic access but lacks a collaborative interface for human users.
• Isolated Container Workspaces: Using temporary sandbox environments to process files, which protects the main corporate directory but loses persistence when the container shuts down.

Establishing isolated folder boundaries is the first line of defense. By restricting applications and agents to designated folders rather than the entire drive, security teams protect corporate files while providing the data context needed to complete tasks. Setting up this isolation requires configuring permissions on the Google Cloud project side. Without strict scoping, external tools gain read and write capabilities over files they do not need to access, increasing the risk of data exposure.

When designing storage pipelines, security teams prefer workspaces that are isolated at the API credential level. If a tool or agent is compromised, the breach is limited to the specific folder shared with that credential. This boundary limits lateral movement across the company's file directories. Developers must design the exact permission structure before executing the first API request to ensure that assets remain secure throughout the workflow.

A primary secure method to unzip google drive files without exposing your account to third-party software is by performing the extraction on your local machine. This method uses your computer's built-in operating system tools to handle the files, ensuring that no external application gets access to your cloud directory.

To unzip files locally, follow these standard steps:

1. Open Google Drive in your web browser.
2. Locate the ZIP archive you want to extract.
3. Right-click the file and select "Download" from the context menu.
4. Wait for the download to complete and find the file on your local machine.
5. Right-click the ZIP file and select "Extract All" (on Windows) or double-click the file (on macOS).
6. Choose the destination folder on your local disk and complete the extraction.
7. Return to Google Drive, click "New", select "Folder upload", and choose the extracted folder to upload the files back to the cloud.

While this approach protects your account from external access, it is highly inefficient for large archives. For example, inspecting a large archive (such as a 10 GB zip) in Google Drive requires downloading the entire file to local storage. This process consumes significant network bandwidth and takes several minutes to complete, making it impractical for teams that handle multiple large archives daily.

Alternatively, you can use the Google Drive for Desktop application. This application mounts your cloud drive as a virtual disk on your Mac or Windows computer. When you open the folder in your file explorer, you can unzip archives directly inside the virtual directory. The desktop client then syncs the newly extracted files back to the cloud automatically. However, this method still requires downloading the ZIP file data in the background, which can cause sync delays and consume local disk space during the extraction process.

If you want to extract zip google drive archives without downloading them to your computer, you can use cloud-based applications from the Google Workspace Marketplace. These tools run directly in the cloud, processing the ZIP file and saving the extracted contents back to your Google Drive.

To extract files using a marketplace app like ZIP Extractor, follow these steps:

1. Open Google Drive in your web browser.
2. Locate the ZIP archive and right-click it.
3. Hover over "Open with" and select "Connect more apps".
4. Search for "ZIP Extractor" and click "Install" to add it to your Google Workspace.
5. Right-click the ZIP archive again, select "Open with", and click "ZIP Extractor".
6. Authorize the application to access your Google Drive by accepting the OAuth consent screen.
7. Select the specific files you want to extract or click "Extract to Google Drive" to extract the entire archive.

Marketplace applications process files quickly because the data transfer happens entirely within cloud servers. This method eliminates the need to download large files to your local drive. However, it introduces significant security and privacy concerns. Many web-based extractors require full read and write access to all files in your Google Drive, meaning your data is exposed to a third-party developer's infrastructure.

Furthermore, these graphical marketplace integrations are designed exclusively for manual human use. They require active browser sessions and manual button clicks to authenticate and extract files. Because they rely on interactive OAuth consent screens and visual interfaces, they cannot be integrated into automated software pipelines. AI coding agents and background processes cannot interact with these browser extensions, forcing developers to look for programmatic alternatives.

For developers and agentic teams, managing ZIP archives in Google Drive introduces operational friction. AI agents cannot use browser extensions or click on Google Workspace Marketplace dialogs. When an agent needs to inspect a ZIP archive, it is forced to download the entire file to its container sandbox, unzip it locally, parse the contents, and then write the results back to storage. This process consumes heavy CPU, memory, and network resources.

Fastio solves this bottleneck by providing an intelligent workspace built for both humans and AI agents. Fastio allows agents to inspect archive metadata via MCP without full downloads. The platform exposes a consolidated MCP toolset that operates over Streamable HTTP at /mcp and legacy SSE at /sse, allowing developers to integrate secure file management into any LLM application by following the Fastio developer documentation.

Using Fastio's Cloud Import tool, developers can connect their Google Drive accounts via secure OAuth to import files directly while preserving the folder structures as detailed on the Fastio storage for agents page. Once the files are in the Fastio workspace, they are processed by the built-in AI engine, Ripley:

• Workspace Intelligence: Ripley automatically indexes imported files, enabling semantic search and natural-language Q&A across the entire directory.
• Collaborative Notes: Humans and AI agents can co-edit notes in real time with visible cursors, establishing a shared space for prompt engineering and project documentation.
• Workflow Automation: Developers can construct visual DAG workflows with triggers and approvals, ensuring that agent actions are governed by human review.

Instead of writing complex code to download and unzip files locally, developers can run a simple API call or MCP command to inspect the contents of an archive. The Fastio workspace serves as the single source of truth, managing version history and activity logs for every file write. This approach eliminates the local storage and bandwidth bottlenecks associated with legacy cloud sync setups, allowing agents to process data-heavy files with minimal latency.

When evaluating file storage for automated pipelines, the differences between legacy sync networks and intelligent workspaces become clear. Google Drive was built for human document synchronization, meaning it lacks the native API tools and metadata inspection features required by automated agents. Fastio bridges this gap by combining secure storage with an intelligence layer that indexes files on arrival.

The following table compares the workflow capabilities of Google Drive and Fastio:

Fastio offers flexible, credit-based pricing across three plans, which you can review on the Fastio pricing page: Starter is priced at $29/mo (1 TB of storage and 300,000 credits), Business is priced at $99/mo (10 TB of storage and 1,200,000 credits), and Growth is priced at $299/mo (50 TB of storage and 4,500,000 credits). The platform has no permanent free plan or free agent tier. Every organization starts with a 14-day free trial that requires a credit card to activate. The trial allows teams to test the full capability of the workspace, including the MCP server and Cloud Import workflows.

The credit system meters resources based on actual usage:

• Storage: Consumes 100 credits per GB.
• Bandwidth: Consumes 212 credits per GB.
• AI Tokens: Consumes 1 credit per 100 tokens.
• Document Ingestion: Consumes 10 credits per page.
• Image Ingestion: Consumes 5 credits per image.
• Video Ingestion: Consumes 5 credits per second.
• File Conversions: Consumes 25 credits per each conversion.

For developers building client pipelines, Fastio supports ownership transfer. An agent can set up the organization, create the workspaces, and import the initial files. Once the setup is complete, the agent generates a claim link to transfer the organization to the human client. The human enters their credit card to start the 14-day free trial, while the developer agent maintains admin credentials to monitor the pipeline. This transfer ensures that the client takes over billing while the agent retains the access needed to run background automations.
