How to get all items checked out to all users in a specific source location
tf status /user:* /recursive "$/My Folder1/My Folder2"

tf status /user:* /recursive "$/My Folder1/My Folder2" | FIND " add "

Step 1) Get workspace and user name of checked out file.
tf status /user:* /format:detailed "$/My Folder1/My File1.txt"

Step 2) Undo checked out file.
tf undo /workspace:myworkspace;myusername "$/My Folder1/My File1.txt"
