Error when trying to upload an SQL file using the source command in MySQL

I am a fairly new student currently enrolled in Python and SQL for Data Science course from a website called Scaler. As part of the course, I am trying to understand the concepts of MySQL.

The instructor provided an SQL file named imdb.sql and demonstrated how to upload it to MySQL using the source command. However, whenever I try to do the same, I encounter the following error:

ERROR:

ERROR:

ERROR:
Failed to open file 'D:qlpracticescaler\imdb.sql', error: 2

I have double-checked the file path and ensured the file exists.

Additional Information: MySQL version: mysql Ver 8.0.37 for Win64 on x86_64 (MySQL Community Server - GPL) Operating system: Windows 64-bit operating system Size of imdb.sql file: 150,181 KB

What could be causing this error, and how can I successfully upload the imdb.sql file to my MySQL database using the source command?

Any help or guidance would be greatly appreciated. Thank you!
