When working in MATLAB, the current directory is crucial as it determines where MATLAB looks for files or saves output. However, you don’t always need to use coding commands to change the current directory. Fortunately, MATLAB provides several easy, non-coding methods for adjusting the working directory. In this blog, we will explore different ways to change the current directory in MATLAB without writing any code. Let’s dive into these practical solutions, which will make your workflow smoother and more efficient.
Understanding the Current Directory in MATLAB
The current directory in MATLAB is essentially the folder where MATLAB looks for files or stores output. Changing the directory allows you to organize your projects better and quickly access the files you need. For instance, when you run a script, MATLAB uses the current directory to find variables, functions, and data files. Keeping the current directory organized ensures that your workspace is efficient and clutter-free. The default directory when MATLAB starts is usually your user folder or Documents folder, but you can change it according to your project requirements.
Using the MATLAB Interface to Change the Directory
One of the easiest ways to change the current directory is by using the MATLAB interface. On the top of the MATLAB window, there is a Current Folder panel. Click on the folder path shown in this panel, which will open a navigation window, allowing you to browse and select a new folder. Once you’ve chosen the desired directory, simply click on it to set it as your new working directory. This method is convenient and eliminates the need for any coding, making it suitable for both beginners and experts.
Using the File Navigation Panel
Another user-friendly option to change the directory is through the File Navigation Panel. This panel is located on the left side of the MATLAB interface. If the panel is not visible, you can open it by going to Home > Layout > Current Folder. Once you’re in the panel, you can navigate through your directories by clicking on folders to open them. Selecting a folder will automatically set it as the current directory, making this method a great way to quickly move between project folders.
Dragging and Dropping Folders into the Current Folder Panel
If you have a specific folder in mind, you can also drag and drop the folder directly into the Current Folder panel. This method works when you have the folder you want to switch to readily available in another window on your desktop. Simply drag the folder into the panel, and it will become the active directory. This technique can save time if you’re working with multiple directories and prefer a visual approach without typing any commands.
Changing the Current Directory with the ‘Set Path’ Tool
MATLAB includes a built-in tool called the Set Path tool, which helps manage the current directory and folder paths. While this tool is typically used for adding directories to MATLAB’s search path, it also allows you to change the current directory easily. You can access the Set Path tool by clicking on Home > Set Path in the top menu. Once the window opens, navigate to the folder you want to set as the current directory and click "OK" to save your selection. This method is particularly useful if you need to change your directory settings on a more permanent basis.
Switching Directories via the MATLAB Command Window
While we’re focusing on non-coding methods, it’s worth mentioning that if you ever need to switch directories with a simple code command, you can use the cd function. This can be especially helpful in cases where you need to quickly switch between directories. However, since you’re looking for non-coding solutions, it’s useful to know that MATLAB’s GUI provides many convenient options for changing the directory without typing any code.
Navigating to a Folder Using the "Browse for Folder" Dialog
In addition to manually navigating through the folder structure, MATLAB offers a "Browse for Folder" dialog that simplifies folder selection. To access it, simply click on the "…" button next to the current directory path in the Current Folder panel. This opens a standard file explorer window, where you can browse and select a folder. Once you’ve found your folder, click "OK" to set it as the current directory. This method can be particularly useful when you’re unsure of the folder path or when you’re working with directories located deep within your file system.

Customizing MATLAB’s Default Start Directory
MATLAB allows you to customize the default directory that is set when the program first launches. To do this, go to Preferences by navigating to Home > Preferences in the menu bar. In the Preferences window, select General > Initial Working Folder. From there, you can specify the folder you want MATLAB to use as its default start directory. Changing this setting ensures that MATLAB always opens to the folder you need for your project, saving time every time you start the program.
Using the ‘Folder Shortcuts’ Feature in MATLAB
MATLAB’s Folder Shortcuts feature allows you to save commonly used directories for quick access. Once you’ve navigated to a folder you use frequently, right-click on it in the Current Folder panel and select Add to Shortcuts. This will add the folder to the shortcuts section, making it easy to switch to with a single click. The shortcuts can be found in the left-hand panel, so you don’t need to manually browse for directories every time. This feature makes it easier for users with large file systems to access their most important folders quickly.
Using the "Open" Command for Files
If you’re working with specific files and want to automatically change to the directory containing them, you can use the Open command in MATLAB. You can open a file by selecting File > Open from the menu or using the open(‘filename’) command in the Command Window. By opening a file directly, MATLAB will automatically change the current directory to the location of that file, saving you the step of navigating to the directory manually.
7 Methods to Change the Current Directory in MATLAB
