What We Learned from 100+ Law Firm iManage Exports
After supporting 100+ law firm exports from iManage, we compiled the data on matter sizes, failure points, and what separates a smooth export from a painful one.
Over the past several years, MatterExport has been used by 100+ law firms 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 small to mid-size firms 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 Numbers
Here's what 100+ law firm iManage exports look like in aggregate:
| Metric | Value |
|---|---|
| Firms using MatterExport | 80+ |
| Average documents per matter export | ~12,000 |
| Median documents per matter export | ~4,500 |
| Largest single export | 140,000+ documents |
| Exports that exceed the 9,999 limit | ~35% |
| Exports affected by long path issues | ~20% |
| Average folder depth | 5-7 levels |
| Most common export reason | Lawyer departure / matter handover |
| Average setup time (first export) | Under 5 minutes |
Finding #1: 35% of Exports Exceed the 9,999 Limit
This was higher than we expected. More than a third of all matter exports we've seen involve more than 9,999 documents — the hard cap in iManage's native export and REST API tools.
These aren't outlier cases. Any firm doing litigation, regulatory work, or large transactional matters regularly produces workspaces this size. The firms hitting this limit aren't doing anything unusual — they just have normal-sized matters that iManage's export wasn't designed to handle.
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.
Finding #2: Long File Paths Break 1 in 5 Exports
About 20% of exports we've seen involve file paths that exceed Windows' 254-character practical path limit. This happens more often than people think because 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. The IT team never knows 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.
Finding #3: Lawyer Departures Are the #1 Reason Firms Export
We expected litigation holds or regulatory responses to be the primary driver. Instead, 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.
The breakdown of why firms export:
| Reason | Frequency |
|---|---|
| Lawyer departure / matter handover | ~40% |
| Client file delivery | ~20% |
| Litigation / regulatory production | ~15% |
| DMS migration | ~15% |
| Backup / disaster recovery | ~10% |

Finding #4: Server Infrastructure Is the Biggest Bottleneck
Among firms that previously used other export tools (Bundledocs, DocAuto, or custom scripts), 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).
Several firms told us their previous workflow was:
- Get request from departing lawyer's partner or HR
- Evaluate server-based export tools — requires networking and procurement approvals
- Wait 1-3 weeks for infrastructure provisioning
- Discover the tool can't export more than 9,999 documents anyway
- Go back to manual export
With MatterExport, that entire chain is replaced by: download, install, configure in Control Centre, export. Same day.
Finding #5: 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
Finding #6: 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.
This is why we priced MatterExport as an annual license ($1,200/year for 10 seats) rather than per-export. Firms that need it tend to need it repeatedly.
Finding #7: 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 for processing. For firms with strict data residency requirements or client confidentiality obligations, that's a non-starter.
Frequently Asked Questions
What is the largest export MatterExport has handled?
Our largest single export was over 140,000 documents from one matter. The export completed without manual intervention. There is no hard document count limit in MatterExport.
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 IT Team
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.
