Need better explination of Permissions.

Turk

These are the "actions" I believe there can be. If there are more please list them for me.

• View File Contents
• Add Files
• Add Folders
• Delete Files
• Delete Folders
• Execute
• Modify Files
• Modify Folders
• View Folder Permissions
• Modify Folder Permissions
• List Files in Folder
• Switch to Sub Folder
• Delete Sub Folder
• Rename Files
• Rename Folders

Now when it comes to which actions can be done under which permissions I'm not sure if my reading material is leaving things out or not. Here is what I believe to be true. Please help me out and let me know if they are correct of need to be changed.

WRITE

• View File Contents
• Add Files
• Add Folders
• Delete Files
• Delete Folders
• Execute
• Modify Files
• Modify Folders
• View Folder Permissions
• List Files in Folder
• Switch to Sub Folder
• Delete Sub Folder
• Rename Files
• Rename Folders

READ

• View File Contents
• View Folder Permissions
• List Files in Folder
• Switch to Sub Folder

LIST FOLDER CONTENTS

• List Files in Folder
• Switch to Sub Folder
• Execute

MODIFY

• View File Contents
• Add Files
• Add Folders
• Delete Files
• Delete Folders
• Execute
• Modify Files
• Modify Folders
• View Folder Permissions
• List Files in Folder
• Switch to Sub Folder
• Rename Files
• Rename Folders

READ AND EXECUTE

• View File Contents
• Execute
• View Folder Permissions
• List Files in Folder
• Switch to Sub Folder

*Some of the thoughts I have is...

• Can READ or LIST FOLDER CONTENTS view and/or modify folder/file permissions?
• Which permissions can modify folder/file permissions?
• I know MODIFY can't delete sub folders or the files in them, but can it modify, add, or rename them?

Thanks for the help everyone. I'm probably leaving a few more holes in what I'm seeing so if you see any list them out please.
