CloudFiles vs S3 Link: Which App Works Better for Salesforce File Storage?

When Salesforce File Storage Starts Becoming a Business Problem

Salesforce Files work well until documents become part of business processes. Contracts may require version history and controlled access, while invoices need to stay associated with the right record. Onboarding documents may also need to be sent to people outside the Salesforce org. As these requirements grow, the question is no longer just where documents are stored. It becomes how they are organised, who can access them, and how they remain connected to the business records and processes they support.

This becomes more important as more teams start using Salesforce to manage documents:

• Sales teams may attach proposals and contracts to opportunities. 
• Service teams may add screenshots, manuals, and troubleshooting files to cases. 
• Customer success teams may keep onboarding documents with account records. 
• Finance teams may need invoices and other financial documents associated with the right customer or transaction.

As the volume and variety of documents grow, keeping everything inside Salesforce can make document management harder to control. Files may need different access rules, clearer folder structures, version management, or sharing options that extend beyond Salesforce users.

At the same time, many companies already have established storage platforms such as Amazon S3, OneDrive, Google Drive, or SharePoint integration with Salesforce. These systems may already be part of the company’s IT strategy, security model, and document management processes.

The growing use of cloud storage also reflects a broader shift in how organizations manage business data. According to Fortune Business Insights, the global cloud storage market is projected to grow from USD 197.8 billion in 2026 to USD 809.99 billion by 2034. As companies expand their use of cloud-based storage, Salesforce does not necessarily need to become the primary location for every business document.

This creates a challenge: how to keep documents accessible from Salesforce while maintaining the organization, access controls, and document management practices they already use.

To solve this problem, many organizations start exploring Salesforce file storage options available on AppExchange (now AgentExchange). These solutions help connect Salesforce with external storage platforms and provide different approaches to managing documents outside the Salesforce database.

For this comparison, we selected two AppExchange solutions: CloudFiles and S3-Link, because both address the challenge of storing Salesforce files externally while keeping them accessible within Salesforce.

In this article, we will compare CloudFiles and S3-Link across key areas such as functionality, usability, storage capabilities, security, and overall fit for Salesforce organizations.

The goal is to understand how these solutions work, what challenges they solve, and which option provides the best approach for different business needs.

To make the comparison as objective as possible, each evaluation category will include a scorecard and star rating based on the capabilities of both solutions. At the end of the article, we will combine the results from all categories to calculate the final score and determine the overall winner.

CloudFiles Quick Overview: Salesforce File Management Beyond Storage

Overview

CloudFiles Document Management is developed by CloudFiles and is designed to help Salesforce organizations manage documents without relying solely on Salesforce file storage.

At its core, the app connects Salesforce with external storage platforms such as Amazon S3, SharePoint, OneDrive, Google Drive and more, allowing users to access and manage files directly from Salesforce while keeping the documents stored externally.

As a Salesforce document management solution, CloudFiles covers multiple stages of the document lifecycle. Teams can organize files, automate folder creation, connect documents to Salesforce records, and manage files stored across different storage providers without leaving Salesforce. 

Setup and configuration

The process of installing and configuring CloudFiles can be broadly divided into the following steps:

• Install the managed package and access CloudFiles. After installing the package from AppExchange, the administrator can open the CloudFiles application from the Salesforce App Launcher and start the initial setup.

• Connect the external storage platform. CloudFiles supports Amazon S3, SharePoint, OneDrive, Google Drive, Azure Blob Storage, Box, and Dropbox. During setup, administrators connect the storage provider that will be used for document storage and configure the required authentication.

• Configure document organization and user access. Administrators can define folder structures, record-linking rules, document libraries, and permission settings to control how users access and manage files.
• Add CloudFiles to Salesforce pages and enable optional features. The final step is adding CloudFiles components to Lightning record pages, configuring optional capabilities such as Flow automation and metadata synchronization. Document Generation and Document AI ship in the same package and are licensed separately.

Key features

CloudFiles supports a wide range of document management capabilities:

• External file storage.
• Amazon S3, SharePoint, Google Drive, Azure Blob integration.
• Automatic folder creation.
• Record-linked document management.
• File previews inside Salesforce.
• File version control.
• Document sharing and collaboration.
• Custom Lightning widgets.
• Experience Cloud support.
• Salesforce Flow integration.

Best fit

For me, CloudFiles fits best when an organization wants more than simply moving files out of Salesforce storage.

The platform is particularly relevant for companies that need centralized document management across multiple storage systems, want to automate document-related processes, or expect their document requirements to grow over time. Organizations using Amazon S3 today but potentially adding SharePoint, OneDrive, or other repositories in the future may also benefit from the platform’s storage-agnostic approach. 

Companies primarily looking for a complete document management strategy (including storage management, document generation, workflow automation, and AI-powered document processing), are likely to find CloudFiles more aligned with their long-term Salesforce roadmap than a solution focused exclusively on storage integration.

S3-Link Quick Overview: Focused Salesforce S3 Connector 

Overview

S3-Link by Neilon Technologies is designed for organizations that want to connect Salesforce with external cloud storage platforms, such as Salesforce to S3 Amazon, and manage files outside Salesforce storage limits.

The main purpose of S3-Link is to move Salesforce files outside the Salesforce platform while keeping them connected to Salesforce records. Instead of storing documents directly in Salesforce File Storage, organizations can use connected external storage repositories and manage files through Salesforce.

The solution is primarily focused on Salesforce Amazon S3 integration. Vendor materials also reference additional storage connections, including Wasabi, while other storage integrations require separate verification.

Setup and configuration

Getting S3-Link ready requires connecting Salesforce with an existing Amazon S3 environment and configuring how files will be managed:

• After installing the managed package from AppExchange, you can open S3-Link from the Salesforce App Launcher, go to the Administration tab, and initialize the application configuration.

• Provide the required Amazon S3 credentials, including the AWS Access Key ID and AWS Secret Key, to allow Salesforce to connect with the AWS environment.

• Link existing Amazon S3 buckets or create new buckets directly from S3-Link. A default bucket can be selected where files attached to Salesforce records will be stored.

• The final step is assigning the required permission sets and granting access to Salesforce users who need to manage files through the application.

Key features

S3-Link focuses on Salesforce and Amazon S3 file management capabilities:

• Connect Salesforce with external storage platforms, including Amazon S3 and vendor-documented additional storage options.
• Move large volumes of Salesforce Files to external storage and reduce Salesforce storage consumption.
• Automate file movement based on schedules or defined conditions.
• Share download links and allow external uploads without Salesforce login.
• Support file editing, annotations, PDF merging, and integrations with document generation solutions.

Best fit

S3-Link is particularly suitable for companies already using Amazon S3 and looking for a Salesforce Amazon S3 connector that allows them to maintain their existing storage architecture instead of moving documents into a new repository.

Security and Governance: Which App Has You Covered?

Security is a critical consideration when moving Salesforce files outside the platform. Organizations need to understand not only where documents are stored, but also how access is controlled, how storage policies are managed, and whether the solution can support future business requirements.

In this section, we will compare CloudFiles and S3-Link based on Salesforce security integration, external storage security, governance flexibility, and the ability to support different enterprise storage strategies.

CloudFiles provides more flexibility from a governance perspective because organizations can choose between multiple documented storage providers and manage different storage strategies through one Salesforce solution.

S3-Link provides documented security controls for Salesforce access and Amazon S3 storage, including authentication and encryption capabilities. Amazon S3 is the primary documented storage integration, while additional storage connections referenced by the vendor require separate verification.

CloudFiles vs S3-Link: Licensing and Scalability Comparison

When evaluating document management solutions, subscription costs are only part of the equation. Organizations should also consider storage flexibility, vendor dependency, and how easily the solution can scale as business requirements evolve.

In this section, we compare CloudFiles and S3-Link based on licensing approach, storage strategy flexibility, and long-term scalability considerations.

Both solutions offer pricing models that can work for different types of organizations, making direct cost comparisons difficult without considering company size, user count, and storage requirements.

The more significant difference lies in storage strategy and long-term flexibility. CloudFiles allows organizations to work with multiple documented storage providers and adapt their document management architecture as requirements evolve. S3-Link provides a focused external storage integration approach with Amazon S3 as its primary documented integration.

Wrapping Up: Finding the Right File Storage in Salesforce
