JetBrains documentation explicitly mentions that changing IDE directory locations is intended for creating portable installations, among other use cases like slow disks or encrypted home directories.
: Keeps your installed extensions within the portable folder. When these are pointed to relative paths (e.g.,
Portable drives are inherently slower than internal SSDs. PyCharm is a resource-intensive IDE that relies on indexing and caching. Running it from a slow USB 2.0 drive will result in a noticeably laggy and frustrating experience. For a tolerable experience, a USB 3.0 or USB-C drive is essential. Even then, large projects will still be slower to index and load compared to an internal drive.
Browse to your USB drive, navigate into the WinPython directory, and select python.exe . Method B: Use the Official Python Embeddable Package pycharm community edition portable
The launcher automatically manages environment paths, configuration files, and system registries upon launch and closure. Bundling Python for True Portability
Python developers often need to work across multiple computers. Setting up a complete development environment on every machine takes time. PyCharm Community Edition is a premier free IDE for Python, but the standard installer requires administrative rights and ties your configuration to a single operating system.
Insert a fast USB 3.0 (or higher) flash drive, or select a synchronized cloud folder like OneDrive or Dropbox. Ensure the drive is formatted to NTFS or exFAT to handle large file numbers and sizes smoothly. Step 2: Download the Portable Archive Navigate to the official JetBrains PyCharm download page. Locate the section. PyCharm is a resource-intensive IDE that relies on
By default, PyCharm saves your preferences, caches, and plugins to the host user's local directory ( C:\Users\Username\Appdata ). To make it truly portable, you must force PyCharm to save these folders onto the USB drive instead.
Plug the USB into a clean machine (or a VM). Run start_pycharm.bat . On first launch:
Will you be switching between different , or just different Windows machines? Share public link Even then, large projects will still be slower
With this change, the "Community Edition" brand name is being retired. All users will have access to a core set of essential features for free, including features previously exclusive to Professional, such as Jupyter Notebook support. If you want access to the complete set of advanced features, you can purchase a Pro subscription or get a 30-day free trial when you first install the unified IDE. This unification means the portable version landscape might shift, but the underlying concepts remain the same.
If you prefer not to edit configuration files manually, you can use automated platform managers like .
