Rename Files with Date Prefix

Rename all files in a SharePoint document library to prefix them with their created date in yyMMdd format (e.g., 251203-Status Report.pdf).

Steps

1. Identify the Target Library

• Use the current document library if the user doesn't specify one.
• Call get_current_list_or_library to get the library ID.

2. Get the Library Schema

• Call get_list_schema to confirm the library has Created and FileLeafRef fields and to understand the structure.

3. Retrieve All Files (Including Subfolders)

• Call get_list_item_metadata with fetchAll: true to retrieve all items.
• Use a CAML query that filters to files only (FSObjType = 0):

  <Query><Where><Eq><FieldRef Name='FSObjType'/><Value Type='Integer'>0</Value></Eq></Where><OrderBy><FieldRef Name='FileLeafRef' Ascending='TRUE'/></OrderBy></Query>
