If you want to remove contacts from a read-only folder, there are a few different ways to go about it. The first way is to use the Windows File Explorer. Open the folder where you want to remove the contacts, and then select the file called “Contacts.” Right-click on this file and select “Properties.” In the “General” tab, click on the “Remove” button next to the “Contacts” field. This will remove all of the contacts from this file. The second way is to use Windows PowerShell. Open an elevated command prompt window by clicking on Start, typing cmd in the search box, and pressing Enter. Then type powershell and press Enter. At the prompt, type get-item Contacts -path C:\Users\YourUserName\AppData\Roaming\Microsoft\Windows Contacts. This will return a list of all of your contacts in a comma-separated value (CSV) format. To remove a contact from this list, type Remove-Item -Path C:\Users\YourUserName\AppData\Roaming\Microsoft\Windows Contacts -Recurse -Force . This will delete that contact from your computer permanently. The final way is to use Microsoft Outlook 2010 or 2013. Open Outlook 2010 or 2013 and open your email account (or create an email account if you don’t have one already). Click on the gear icon in the top right corner of Outlook 2010 or 2013 and select “Mail Settings.” In the “Mail Settings” window, click on the “Accounts” tab and then select your email account from the list that appears. Underneath your email account name, click on “Contacts.” You’ll see a list of all of your contacts in this window. To delete a contact from this list, double-click on that contact’s name and then click on “Delete.” ..
