Copying Large Files

Overview

You need to copy a very large file - at least in the gigabyte, often hundreds of gigabytes range. You are finding that it is slow (mb/sec) or fails.

This is often encountered when copying the EHR database (e.g. the Works DB for Allscripts) file, especially over a network.

Option 1

Use Eseutil. This is the solution recommended by Microsoft - technically, the Enterprise Platforms Support Windows Server Performance team. You can check out the article here.

It is a command-line program. The usage for file copies is: eseutil /y <srcfile> /d <destfile>

Option 2

A client of Galen's has used CLF with consistent success copying a 400gb file across its network.
