Folders
Folders help you organize snippets by project, topic, language, or any structure that fits your workflow. When you select a folder in the sidebar, massCode shows snippets from that folder and all of its subfolders in the second column.
Adding a Folder
Use one of these methods:
- Select "File" > "New Folder" from the menu bar.
- Click the "+" button next to "FOLDERS" in the library.
- Press Shift+Cmd+N on macOS or Shift+Ctrl+N on Windows or Linux.
Moving to Folder
Drag one folder onto another to create a nested folder structure.
Renaming and Deleting
Right-click the folder and choose "Rename" or "Delete".
WARNING
Deleting a folder moves all its snippets and subfolders to "Inbox".
Set the Default Folder Language
Set a default language when most snippets in a folder use the same syntax.
Right-click the folder and choose "Default Language".
Setting a Folder Icon
Folder icons help large libraries stay easier to scan. Right-click a folder and choose Set Icon. Use the Icons tab to search the built-in Material and Lucide icon collections.
To restore the default folder icon, right-click the folder and choose Remove Icon.
Emoji and Uploaded Images
The icon picker also supports:
- Emoji - search the Unicode emoji catalog. Emoji appearance follows your operating system.
- Upload - choose or drop a JPG or PNG image up to 10 MB, review the preview, then click Use image.
Uploaded images are cropped from the center, resized to 128×128, and saved as PNG.
Uploaded icons are stored as a hidden .icon.png file inside the folder, so they stay with the folder when you back up or sync your Markdown Vault.
