  3️⃣ Install Perforce Command-Line Client (Optional):
• P4Win works best with P4 (CLI) installed. Download it from the Perforce website.
  4️⃣ Launch P4Win:
• Open P4Win.exe from the Start menu.

3. Understanding the P4Win Interface

The P4Win UI is divided into multiple panels:

Main Sections:

📁 Depot View (Left Panel) – Shows the entire Perforce repository
📂 Workspace View (Right Panel) – Displays your local workspace files
📜 Pending Changelists (Bottom Panel) – Lists your submitted and pending changes

👉 Right-clicking files/folders provides quick access to actions like Check Out, Submit, Revert, and Diff.

4. Working with Files

a) Checking Out Files (Edit a File)

To modify a file, you must check it out from Perforce.
✔ Right-click the file → Select Check Out for Edit
✔ The file is now writable in your workspace
✔ It will appear in the Pending Changelist

b) Submitting Changes (Check-in a File)

Once you finish editing:
✔ Right-click the file → Submit
✔ Add a description for the changelist
✔ Click Submit

c) Reverting Changes (Undo Edits)

If you want to undo changes before submitting:
✔ Right-click the file → Revert
✔ Confirm to discard your modifications

5. Working with Changelists

A changelist is a set of related changes that you submit together.

Creating a New Changelist:

1️⃣ Go to Pending Changelists
2️⃣ Click New Changelist
3️⃣ Add files to the changelist
4️⃣ Add a description
5️⃣ Click Submit

💡 Tip: Use meaningful changelist descriptions to track work effectively.

6. Managing Branches and Labels

a) Branching (Copying Files to a New Path)

To create a branch:

✔ Choose a destination path
✔ Click OK

b) Labeling (Tagging a Snapshot)

To create a label (snapshot of file versions):
✔ Go to Tools → Labels
✔ Click New Label
✔ Name the label (e.g., Release_1.0)
✔ Select files to include
✔ Click Save

🔹 Labels help in versioning releases efficiently!

7. Resolving Conflicts

If multiple users edit the same file, Perforce may detect conflicts.

How to Resolve Conflicts:

1️⃣ Right-click the conflicting file → Resolve
2️⃣ Compare the local and server versions
3️⃣ Choose an action:

• Accept Yours (Keep your changes)
• Accept Theirs (Take the latest Perforce version)
• Merge (Combine both changes manually)
  4️⃣ Click Submit

✅ Tip: Always review changes before merging!

To track changes:
✔ Right-click a file → Select File History
✔ See previous versions, authors, and timestamps

To compare changes:

9. Best Practices for P4Win Users

✔ Use descriptive changelist descriptions
✔ Sync your workspace regularly (Right-click → Get Latest Revision)
✔ Resolve conflicts immediately to avoid merge issues
✔ Label important versions for easy rollback
✔ Use branches for parallel development (e.g., features, bug fixes)
