Installation

Step 1 - Download ezfetch.ps1 from github

• In a browser window, click here: https://github.com/dwbrott/ezfetch
• Download ezfetch.ps1 and save it into a folder on your computer where you will run it

Step 2 - Add ezshare.card to hosts file

Since the ezcard HTTP servers redirects you to host called 'ezshare.card' you will need to modify the local hosts file on your Windows computer. This is the one step that will require you to be in Adminstrator mode on your PC.

• Start your favorite text editor (e.g. Notepad) in Administrator Mode
  • Click Windows -> Type Notepad
  • Right click on Notepad
  • Choose "Run as Administrator" to run in Administrator Mode
  • Start the application
• (Assuming Notepad) - Click File -> Open
• Open File: %WINDIR%\System32\drivers\etc\hosts
• Add the text below to the end of the hosts file

192.168.4.1    ezshare.card

• Save the file
• Close the editor

Step 3 - Confirm ezshare.card hostname works

• Click Windows -> Type Powershell
• Click on Windows Powershell App (do not start as Administrator)
• Enter the following command in Powershell

ping ezshare.card

• If the hostname file was edited correctly, you should see the following:

Pinging ezshare.card [192.168.4.1] with 32 bytes of data

• Note: The ping test itself will likely fail (Request timed out), that's OK. You want to make sure you see this part: ezshare.card [192.168.4.1]

Step 4 - Navigate to installation folder in Powershell application

• Navigate to the folder where you installed ezfetch.ps1
• In the Powershell application you started above
  • use dir command to see contents of folder and
  • use cd command to change to the correct folder
• Note: If you have OneDrive, you may need to go to OneDrive folder first

Step 5 - create the data directory

• In the folder with ezfetch.ps1
• Enter the following command in Powershell

md data

Step 6 - Confirm you can access the card

• Enter the following command in Powershell

ping ezshare.card

• This time you should see a Reply from the card like this

Pinging ezshare.card [192.168.4.1] with 32 bytes of data: 
Reply from 192.168.4.1: bytes=32 time=7ms TTL=255

Reply from 192.168.4.1: bytes=32 time=2ms TTL=255 
Reply from 192.168.4.1: bytes=32 time=2ms TTL=255 

• If you don't see replies from the ez Share card, go back and troubleshoot

Step 7 - Run the ezshare.ps1 script

• Enter the following command in Powershell

ezshare.ps1

• Watch as your data is downloaded (grab some coffee it will likely be slow)
• Subsequent runs will skip files already downloaded
