Back up your VSCode extensions on Linux? It's actually pretty straightforward once you know where everything lives. Whether you're switching machines or just reinstalling your system, keeping track of your installed extensions can save you a lot of time. Here’s how to do it properly without any fuss.

Where does VSCode store extension data on Linux?

VSCode keeps all user-specific data — including extensions — under a hidden directory in your home folder. Specifically, the path is usually:

~/.vscode/extensions/

That’s where all the installed extensions are stored. If you want to back them up, this is the main folder you’ll need to copy. Also, if you use VSCode Insiders or another variant, the folder might be named .vscode-insiders instead.

You don’t have to remember that path exactly — just know that backing up this folder will let you restore your extensions later.

How to back up your extensions

To create a backup, simply copy the entire extensions folder somewhere safe. You can do it from the terminal like this:

cp -r ~/.vscode/extensions /path/to/backup/location/

Or you can use a file manager — just make sure hidden files are visible so you can find .vscode.

If you're preparing for a system reinstall or migration, also consider exporting your list of installed extensions using:

code --list-extensions > extensions-list.txt

This creates a plain text file with one extension per line. Handy for reference or reinstalling quickly later.

Restoring extensions from backup

When you're ready to restore your extensions after a fresh install or move:

1. Make sure VSCode is closed.
2. Copy the backed-up extensions folder back to ~/.vscode/.
3. Open VSCode — it should recognize those extensions as already installed.

If you only saved the list (extensions-list.txt), you can reinstall all extensions with:

cat extensions-list.txt | xargs -L 1 code --install-extension

It’ll try to install each one automatically. Some might fail if they’ve been removed from the marketplace, but most should work fine.

A few things to watch out for

• Extensions sometimes store extra settings or cache elsewhere (like ~/.config/Code), but the main logic is in the extensions folder.
• If you’re switching between different OSes or architectures (like moving to an ARM-based machine), some native extensions might not work directly and may need recompilation or updates.
• Always double-check the extension list after restoring — some might not load correctly and may need manual reinstalling.

Backing up and restoring VSCode extensions on Linux doesn’t require any special tools — just basic file management and a couple of commands. Keep your extension folder or list handy, and you'll never have to manually search for every tool again.基本上就這些。
