This question was previously asked in
RRB JE 2025 CBT 2 Mechanical and Allied Engg Question Paper English (2-Jul-2026) (Shift-1)
The correct answer is

Using the Search box in File Explorer with *.ext

In Windows File Explorer, you can use wildcard characters to search for files:

  • * (asterisk) represents any number of characters
  • *.ext finds all files with the specified extension

Examples: *.pdf finds all PDF files; *.docx finds all Word documents.

Type the pattern in the search box (top-right in File Explorer) and press Enter.

This is more efficient than browsing through directories or using the dir command, and works across the selected folder and subfolders.
