What We Learned from 100+ Law Firm iManage Exports

Over the past several years, MatterExport has been used by 100+ organisations to export documents from iManage Work 10 — both on-premises and cloud deployments. We've seen matters ranging from a handful of documents to well over 100,000 — across firms of all sizes that need a fast, reliable way to get documents out of iManage without standing up server infrastructure.

We compiled what we've learned into this article. Some of it confirmed what we expected. Some of it surprised us.

The 9,999 Document Limit Is a Common Problem

A significant proportion of matter exports we've handled involve more than 9,999 documents — the hard cap in iManage's native export tools. Any firm doing litigation, regulatory work, or large transactional matters regularly produces workspaces this size.

Without a tool like MatterExport, firms resort to manual batching — exporting 9,999 documents at a time, renaming folders, and repeating. For a 50,000-document matter, that's 5+ manual rounds. It takes hours and is prone to missed or duplicated files.

Long File Paths Break More Exports Than You'd Think

A common issue we see is file paths that exceed Windows' 254-character practical path limit. iManage allows deeply nested folder structures with long descriptive names — exactly what you'd expect from a well-organized legal matter.

A path like Client Name / Matter / Correspondence / External / Opposing Counsel / Smith & Partners / Response to Motion for Summary Judgment - Amended Draft v3.docx easily exceeds 254 characters when exported to a local drive.

Most export tools (including native iManage export) silently skip these files. You don't know they're missing until a lawyer asks for a document that isn't there. MatterExport handles long paths natively — no files are ever silently dropped.

Lawyer Departures Are the #1 Reason Firms Export

The most common reason firms export from iManage is a departing lawyer — the firm needs all their matters exported, often to a USB drive or network share, sometimes under tight deadlines. Other common use cases include client file delivery, litigation or regulatory production, DMS migration, and backup or disaster recovery.

Server Infrastructure Is the Biggest Bottleneck

Among firms that previously used other export tools, the single biggest complaint was infrastructure overhead. Getting a web server provisioned, waiting for networking approvals, configuring firewall rules — these steps added days or weeks to what should be a 5-minute task.

This is exactly why MatterExport is built as a desktop app that needs no server infrastructure. No web server. No networking approvals. It connects to iManage via the REST API and runs on a single machine. Setup in Control Centre is trivial — for cloud, install from the approved apps list (one click); for on-prem, import a manifest file (~30 seconds).

With MatterExport, the workflow is: download, install, configure in Control Centre, export. Same day.

Folder Structure Preservation Is Non-Negotiable

Every firm we've worked with considers folder structure preservation essential. When exporting a matter, the folder hierarchy IS the organizational system. Flatten it, and the export is almost useless — nobody can find anything.

MatterExport preserves the exact iManage folder hierarchy, including:

• All nested subfolder levels (we've seen structures 12+ levels deep)
• Folder names exactly as they appear in iManage
• Document ordering within folders
• Metadata exported to CSV metadata files and HTML export reports containing document profile properties (author, created date, modified date, document type, custom fields), cumulative across multiple export runs
• All document versions — not just the latest — giving you a complete version history for audit and compliance

Firms That Export Once Always Export Again

One pattern we see consistently: firms that run their first export always come back for more. The initial use case might be one departing lawyer or a regulatory response, but once the team sees how easy it is, it becomes part of the standard workflow.

Data Security Is a Deal-Maker

For law firms handling privileged and confidential documents, the fact that MatterExport operates 100% locally is often the deciding factor. Documents go directly from the iManage server to the user's local machine. Nothing passes through our servers or any third-party cloud infrastructure.

This matters because some competing tools route data through their cloud by default for processing. For firms with strict data residency requirements or client confidentiality obligations, that's a non-starter.

Frequently Asked Questions

Does MatterExport work with iManage Cloud?

Yes. MatterExport is a standalone Windows desktop app (x64) that works with iManage Work 10, both on-premises and cloud. It connects via the iManage REST API. Control Centre setup is trivial — install from the approved apps list for cloud, or import a manifest file for on-prem.

How long does a typical large export take?

Speed depends on your network connection to the iManage server and document sizes. A 10,000-document export typically takes 15-30 minutes. A 100,000-document export can take a few hours. MatterExport runs in the background and can queue multiple exports.

Can I verify that all documents were exported successfully?

Yes. MatterExport provides a detailed HTML export report with total documents exported, any files that couldn't be retrieved (with reasons), and a full log for audit purposes.

What This Means for Your Firm

If your firm uses iManage Work, the odds are good that you've already run into at least one of these issues — the 9,999 limit, long path failures, server infrastructure requirements, or data security concerns with cloud-based tools.

MatterExport was built specifically to solve all of them. It's a desktop app — no server to provision, no networking to configure. Purchase same-day with a credit card in minutes, not weeks. Download the free trial and test it with your most complex matter. If it works for your worst case, it'll work for everything.
