In the video below we'll show you an overview of all the features in the Documents page. For more details we refer you to the linked articles.

Archive file upload and extraction

Emma supports uploading archive files to the Documents page. The following archive formats can be uploaded:

• Zip archives (.zip)
• 7z archives (.7z)
• Rar archives (.rar)
• Tar archives (.tar)
• Gzip-compressed tar archives (.tar.gz, .tgz)
• Bzip2-compressed tar archives (.tar.bz2)
• XZ-compressed tar archives (.tar.xz)
• Gzip archives (.gz)

When you upload any of these archive formats, Emma automatically extracts their contents. Each extracted file inside the archive is ingested individually and appears as its own document entry. The original archive file itself is not stored in the Documents list—only its contents will appear after extraction.

If an uploaded archive is password-protected, Emma will not extract its files and will mark it as an unsupported document type in your Documents list.

Processing activity and problems

A live indicator in the top bar shows what Emma is currently doing in your data room without needing to refresh the page:

• Processing tasks... appears while documents are being analyzed.
• Generating summaries... is shown when Emma is writing or refreshing check summaries.
• Tasks need attention displays when a file could not be processed and requires your attention.
• A green checkmark slides in when all tasks have finished with no outstanding actions.

Tracking this live activity gives M&A lawyers and deal teams immediate awareness of document readiness, processing progress, and emerging issues that could impact deliverable timelines or require escalation.

Clicking the activity indicator opens the activity panel, where processing jobs are grouped into four tabs:

• Queued: Waiting to be processed.
• Processing: Currently being analyzed.
• Problems: Files that could not be processed, with reasons.
• Completed: All tasks finished successfully.

Viewing processing issues

The Problems tab lists each file Emma could not process, and for every failed file displays a clear message explaining why the file could not be analyzed (for example: corrupt, encrypted, too large, or unsupported file type). Each row lets you open the affected document directly. The same failure reason also appears when you hover the warning icon shown next to a file in the document list.

For M&A practitioners, this improved transparency means you can act immediately to resolve analysis blockers—for example, you can see at a glance which critical contracts or compliance documents may be unreadable, and respond before gaps delay the diligence process or risk missed disclosures.

What to do if a file cannot be analyzed

• For files that Emma cannot analyze (such as encrypted or corrupted files), upload a readable version—such as a decrypted or clean copy—so Emma can process and extract its contents.
• Files that fail for transient reasons (e.g., analysis failures) are retried automatically. You do not need to take action on these unless the file stays in the Problems tab after some time.
• If a document remains in Problems after you have uploaded a valid copy and waited, contact support for further review.
