How to download compressed files using idm

Overview

When you request a zip download from Firmex that is larger than 5GB in size, the download is split into multiple parts:

• Part 1 is a .zip file
• Part 2 is a .z01 file
• Part 3 is a .z02 file
• etc.

You must download all of these parts to your computer in order to view the download. You must also use an application like WinRAR (Windows) or Winzip (Windows or Mac) to extract the download, rather than your operating system’s built-in zip extractor.

1. Download all the parts to the same folder on your computer

Download all the parts to the same location on your computer before trying to extract the .zip file.
For example, if your download contains three parts, your folder should contain one .zip file, a .z01 file, and a .z02 file.

What do I do with the .z01 and .z02 files?

You do not need to do anything with the .z01 and .z02 files. WinZip and WinRAR will extract the contents of the files for you.

2. Download WinZip or WinRar

You will need an application like WinZip or WinRar to extract the .zip files and .z01 files.

Download WinZip (Windows or Mac)or
Download WinRar for Windows

3. Extract the .zip file

Right-click the .zip file and choose WinZip > Extract to here or Extract Here with Winrar. The contents of your bulk download will be extracted to the folder you are in. There is no need to click the .z01 or .z02 files.

4. Viewing the content of the bulk download

The extracted content contains an interactive web-page of your project, and a folder structure containing your project’s documents. Both may be copied to a DVD or USB for backup purposes.
