I have a spreadsheet that I update frequently. I'd like to move it from my local folder to a Teams/Files folder. If the file is in Teams, can I create a desktop shortcut to the file so I can open it quickly?
You have two options. You can use open in SharePoint button once uploaded to get to the file in SharePoint )where your files are stored in teams) and open the file. Here you can copy the URL and create a shortcut file on your desktop and paste that in.
Another option would be to open in SharePoint. Then if you have onedrive setup you can utilize the add to onedrive / my files link for the channel. This will add a link with the files In your onedrive folder synced to your computer which you can then create a desktop shortcut for those files.
Same can be done with sync but that’s the old method and recommend using the add to my files / onedrive option over it.
