+# 04 — Creating directories
+
+🌍 **English** · [Türkçe](../../tr/04-create-directory/readme.md) · [Deutsch](../../de/04-create-directory/readme.md) · [Français](../../fr/04-create-directory/readme.md) · [Русский](../../ru/04-create-directory/readme.md)
+
+## The quick way
+
+1. Open the repository, or the folder you want the new folder inside.
+2. **Add File → New Directory**.
+3. Type the folder name, e.g. `docs`.
+4. Press **Commit Changes**.
+
+The panel shows where the folder will be created (`current/path/`) above the name box, so you always know where you are.
+
+## Nested folders in one go
+
+Type a path instead of a single name:
+
+```
+docs/images
+```
+
+That creates `docs`, and `images` inside it, in a single commit.
+
+## Why a `.gitkeep` file appears
+
+Version control tracks *files*, not empty folders. To keep a folder that has nothing in it yet, KabaForge puts an empty file named `.gitkeep` inside. It has no effect on your project — delete it once the folder has real content, or simply leave it.
+
+## The other way: create a folder while creating a file
+
+**Add File → New File** and type a path in the name box:
+
+```
+reports/2026/january.md
+```
+
+Both folders and the file are created together. Use this when you already know the first file.
+
+## Naming rules that save you pain
+
+| Avoid | Use |
+|-------|-----|
+| `Ağ Ödevi (1)` | `network-lab-01` |
+| `My Notes` | `my-notes` or `notes` |
+| `resimler ve ekler` | `assets` |
+
+Folder names with **spaces** or brackets make links harder to share, and relative image paths inside Markdown are more fragile. Lowercase letters, digits and hyphens are always safe.
