# Why Version Control Exists: The Pendrive Problem

**1\. Why Version Control Exists**  
Version control helps track code changes, avoid data loss, and allow multiple developers to work together safely.

**2\. Pendrive Analogy in Software Development**  
Earlier, developers shared code using pendrives, emails, or folders like *final*, *final\_v2*, *latest\_final*, which caused confusion about the correct version.

**3\. Problems Before Version Control Systems**

* Code overwriting
    
* Lost changes
    
* No change history
    
* Poor team collaboration
