Introduction

You open your laptop, trying to find the slides for Lesson 3 to make a quick edit.

You vaguely remember that “there’s a file somewhere”… but when you search, you see:

• final.pptx
• final_v2.pptx
• lesson3_edit.pptx
• lesson3_edit_new.pptx
• lesson3_edit_latest_THISONE.pptx

Ten minutes pass.

And you’re still not sure which file is the one currently in use.

If this situation feels familiar, the problem is not your memory—

it’s how your lesson files are named.

This article will help you:

• Understand why file naming is more important than you think
• Learn a file naming system that never gets messy, even with multiple courses
• Apply it immediately as a teacher, content team member, or course creator on Ourdemy

1. Why Is Naming Lesson Files So Important?

Naming files is not just a “nice-to-have” habit.

It directly affects three critical areas:

1️⃣ Work efficiency

• How fast you can find files
• Whether you open the correct file—or the wrong one
• Whether you feel confident editing, or hesitate out of fear of breaking something

2️⃣ Consistency as your course grows

At first, you may only have 5–10 lessons.

But as the course expands:

• Updates are added
• Multiple courses exist
• More people collaborate on the content

👉 Messy file names = a messy system

3️⃣ Student experience (indirectly)

If instructors:

• Upload the wrong file
• Miss slides
• Deliver mismatched lesson content

Then no matter how good the platform is, the learning experience suffers.

2. Why Do New Ourdemy Course Creators Get Confused So Easily?

When creating a course on Ourdemy, the workflow usually looks like this:

• Create lesson → save file → upload to lesson
• Make edits → save a new file
• Add slides, PDFs, worksheets to the same lesson

When the course is small, everything feels fine.

But as lessons increase or older content needs updating, problems appear:

• You can’t remember which file is currently used
• You have to open files one by one to check
• It’s easy to upload to the wrong lesson
• You hesitate to edit because the content is already public

👉 The issue is not Ourdemy, nor the number of lessons.

Ourdemy provides clear lesson management and update functionality.

The real problem is that file names don’t support the upload and management process.

Your file name is the “map” that guides the right content to the right lesson on Ourdemy.

3. Common File-Naming Mistakes That Cause Upload Errors

❌ No lesson numbers

Introduction.mp4
MainContent.mp4
Summary.mp4

➡️ Files won’t appear in the correct lesson order on Ourdemy.

---

❌ File names that don’t describe the content

Lesson1.mp4
Lesson2.mp4

➡️ After some time, you won’t remember which Ourdemy lesson they belong to.

---

❌ Using “final – final2 – edited”

Lesson1_Intro_final.pptx
Lesson1_Intro_final2.pptx

➡️ You can’t tell which file is currently live on Ourdemy.

4. The Core Principle to NEVER Get Confused

A simple but extremely important rule:

A file name should tell you exactly which lesson it belongs to—without opening the file.

A good file name should answer:

1. Which lesson number is it?
2. What is the main content?
3. Is it a video, slide, or downloadable material?
4. Is this the active version?

If you need to open the file to check → the file name is not good enough.

✅ 3 Principles for Error-Free Uploading

You don’t need a complex system.

Just follow these 3 rules:

1️⃣ Always include the lesson number

Use 01, 02, 03… so files auto-sort and match the lesson order on Ourdemy.

2️⃣ Use one consistent format for the entire course

Once you choose a naming format, apply it to all files uploaded to Ourdemy.

3️⃣ File names should clearly indicate the target lesson

If you need to open the file to check its content → rename it.

5. Recommended File Naming Structure for Ourdemy Courses

A simple, practical structure:

[Lesson Number]_[Lesson Title]_[File Type]

Examples:

01_Introduction_Video.mp4
02_BasicVocabulary_Slides.pptx
03_Practice_PDF.pdf

➡️ At upload time, you instantly know where each file belongs on Ourdemy.

---

Lesson Videos

02_FoundationKnowledge_Video.mp4

If a lesson has multiple videos:

02_FoundationKnowledge_Part1_Video.mp4
02_FoundationKnowledge_Part2_Video.mp4

➡️ Videos stay in the correct order inside the lesson.

---

Slides & PDFs

02_FoundationKnowledge_Slides.pptx
02_FoundationKnowledge_PDF.pdf

➡️ Avoid accidentally uploading internal slides to students.

---

Downloadable Materials for Students

03_Practice_Worksheet.pdf
03_Practice_Exercises.pdf

➡️ Students immediately understand the purpose of each file.

6. Combining File Names and Folder Structure for Long-Term Management

Before uploading to Ourdemy, organize your files into folders:

Course_ABC
│
├─ Lesson01_Introduction
│   ├─ 01_Introduction_Video.mp4
│   ├─ 01_Introduction_Slides.pptx
│
├─ Lesson02_FoundationKnowledge
│   ├─ 02_FoundationKnowledge_Video.mp4
│   ├─ 02_FoundationKnowledge_Worksheet.pdf

➡️ One folder per lesson

➡️ Fast uploads, no need to recheck files

---

7. A Simple Trick to Never Upload to the Wrong Lesson on Ourdemy

Before uploading, ask yourself:

Does this file name match the lesson name on Ourdemy?

Example:

• Lesson: Lesson 5 – Basic Sentence Structure
• File:

Lesson05_Basic-Sentence-Structure_Slides.pdf

➡️ Just by looking at the file name, you know it’s correct.

Conclusion

In short, naming your lesson files is not just about “keeping things tidy.”

It is how you lay the foundation for your entire course in the long run.

When lessons are clearly numbered and a consistent file-naming format is applied from the beginning, you can upload your materials more accurately, avoid confusion when working on platforms like Ourdemy, and save time by not having to recheck content every time you make updates.

• Your course stays well organized and easy to expand
• Updating and adding new lessons becomes much smoother
• You work with confidence, without the stress of uploading the wrong file

A clear and consistent file-naming system allows you to focus on developing your content, instead of dealing with small but frustrating technical issues.

And when the “foundation” is solid, building and growing your course becomes far more seamless and sustainable.
