# Feature Matrix

BabelBird Enterprise Drive can be understood through the full file lifecycle: upload, creation, preview, editing, synchronization, sharing, permission control, version retention, search, archiving, audit, automation and AI retrieval. Actual availability depends on the deployed version, licensed modules and administrator configuration.

## Key New Or Easily Missed Capabilities

### Encrypted Folder

Encrypted folders are password-protected folders inside shared enterprise drive spaces. Users create them from the New menu, enter a folder name and password, and receive a folder with a lock indicator. Opening the folder requires the password each time; even when files inside are shared, recipients still need the encrypted folder password to access the content.

The password must be kept by the creator. The feature uses anonymous encryption, so a lost password cannot be recovered by operators or engineers. See [Encrypted Folder](encrypted-folder.md).

### Sensitive Content Recognition

Sensitive content recognition lets administrators configure sensitive keywords or recognition policies in the enterprise console. Files detected as sensitive can be marked and, depending on configuration, restricted from viewing, sharing or routed to manual handling. It is useful for contracts, certificates, personal data, customer materials, finance files, R&D materials and regulated content. See [Sensitive Content Recognition](sensitive-content-recognition.md).

### Waterfall View

The waterfall view is designed for image-heavy scenarios. It lets users browse material files, design images, product photos, drawings and campaign assets as thumbnails. Image-heavy folders can be switched or adapted to waterfall mode and combined with material libraries, tags, image metadata, text-to-image search and image-to-image search. See [Waterfall View](waterfall-view.md).

### OCR Image Recognition

OCR image recognition covers search, Zhichao AI and image preview. Users can search text inside images; private-cloud deployments can optionally search image-based PDF documents and images embedded in Office files. Zhichao AI and the image previewer can also extract text and export the result as Word. See [OCR Image Recognition](ocr-image-recognition.md).

### Batch Rename And Image Metadata

Batch rename applies naming rules to selected files immediately. It is useful for migration intake, photo cleanup, contract scan archiving and project deliverable organization. Image metadata can participate in advanced search, waterfall filtering, material library management, auto rename and batch rename. See [Batch Rename](batch-rename.md) and [Image Metadata](metadata-search.md).

### Watermarked Downloads

Watermarks apply not only to previews but also to download and print scenarios. Administrators can combine download permissions, preview-only access, sharing policies and PDF conversion to allow users to download watermarked PDF files, preserving visitor or enterprise identifiers in outbound materials. See [Watermark](watermark-security.md).

## Usage Guidance

1. Map the workflow around file intake, collaboration, sharing, archiving and retrieval before choosing modules.
2. For sensitive files, combine permissions, file access control, watermarks, encrypted folders, sensitive content recognition, audit logs and download controls.
3. For image and material scenarios, prioritize material libraries, waterfall view, tags, image metadata, text-to-image search and image-to-image search.
4. For repetitive file handling, use automation tasks to standardize naming, organizing, PDF conversion, cleanup and folder creation.
5. For AI usage, confirm knowledge scope, permission inheritance, model deployment, data flow and audit requirements first.
