Visual Studio Code – How can I easily reinstall all uninstalled VS Code extensions that have their files still lingering in my ~/.vscode/extensions folder?

Windows(CMD) Kinda buggy and some extensions fail to install

go to the extensions folder for vs code

open it

open command prompt and cd into the extensions folder

run this command

dir "C:Users%USERPROFILE%.vscodeextensions" /b > extensions.txt

you will get a file with all the sub folders in the folder but the names will have this format {name}-{version} and we need {name}@{version} to install things properly so we need to use this python script

with open("C:\Users\%USERPROFILE%\.vscode\extensions\extensions.txt", "r") as f:
    filenames = f.readlines()

for filename in filenames:
    filename = filename.strip()  # Remove newline character at the end of the line
    name_parts = filename.split('-')  # Split the filename by the dash character
    version_index = None
    for i, part in enumerate(name_parts):
        if part[0].isdigit():  # Check if the first character of the part is a digit
            version_index = i  # Save the index of the part that contains the version number
            break  # Stop looking for the version number
    if version_index is not None:
        name_parts[version_index] = '@' + name_parts[version_index]  # Add @ symbol before the version number
    new_name = '-'.join(name_parts).replace('@.', '.')  # Create the new filename
    new_name1 = new_name.replace("-@", "@")
    print(new_name1)

copy the output in the terminal which will be {name}@{version} and save it to the same extensions.txt file in the folder

then go back to cmd and run this command

for /f "usebackq delims=" %i in (extensions.txt) do code --install-extension %i

all extensions will start to be installed

IMPORTANT DETAIL when you run the first command the file may have 1 or 2 files that are in the extensions folder like the extensions.json so delete those from the extensions.txt file
