Does Bash On Windows Take A Lot Of Space


As an avid user of both Windows and Linux, I’ve always been intrigued by the integration of the two systems. One feature that caught my attention is the ability to run Bash on Windows, which allows me to use Linux command-line tools directly within the Windows operating system. However, one common question that I’ve come across is whether running Bash on Windows takes up a significant amount of space on the system.

Understanding Bash on Windows

Before we dive into the space considerations, let’s first understand what Bash on Windows actually is. It’s essentially a feature that enables the Windows Subsystem for Linux (WSL), allowing users to run a Linux environment directly on a Windows machine. This means you can access the familiar Linux command-line tools and utilities without the need for a virtual machine or dual-boot setup.

Space Considerations

Now, onto the main question – does running Bash on Windows consume a lot of space? Well, the answer is both yes and no. When you first enable WSL and install a Linux distribution such as Ubuntu or Fedora from the Microsoft Store, it does take up a noticeable amount of disk space. The initial download and installation can be several gigabytes, depending on the selected distribution.

However, once the Linux environment is set up, the space consumption is reasonable. The WSL uses a lightweight virtualization technology and a filesystem translation layer, which means that it doesn’t require a separate partition or significant additional disk space beyond the initial installation.

Personal Experience

From my own experience, I found that enabling WSL and installing Ubuntu on my Windows machine took around 1.5 GB of space. While this may seem substantial at first, the benefits of having a fully functional Linux environment within Windows outweigh the initial space allocation for me.


In conclusion, while enabling Bash on Windows and setting up the Windows Subsystem for Linux may initially consume a noticeable amount of space, the ongoing space requirements are reasonable. The convenience and functionality of having a Linux environment directly within Windows make the space trade-off well worth it in my opinion.
