+# Delete __XLDIR__ Directory Scripts
+
+This directory contains scripts for deleting all directories ending with `__XLDIR__` in the specified path.
+
+## Script Description
+
+### 1. delete_xldir.sh (Full Version)
+
+A feature-rich version with multiple options and safety checks.
+
+**Usage:**
+```bash
+./scripts/delete_xldir.sh <path> [options]
+```
+
+**Options:**
+- `-f, --force`    Force deletion without confirmation
+- `-v, --verbose`  Show verbose information
+- `-d, --dry-run`  Show directories to be deleted without actually deleting
+- `-h, --help`     Show help information
+
+**Examples:**
+```bash
+# Preview directories to be deleted (without actually deleting)
+./scripts/delete_xldir.sh /path/to/search --dry-run
+
+# Interactive deletion (will ask for confirmation)
+./scripts/delete_xldir.sh /path/to/search
+
+# Force deletion (without confirmation)
+./scripts/delete_xldir.sh /path/to/search --force
+
+# Verbose mode deletion
+./scripts/delete_xldir.sh /path/to/search --verbose
+```
+
+### 2. delete_xldir_simple.sh (Simple Version)
+
+A streamlined version that directly deletes found directories.
+
+**Usage:**
+```bash
+./scripts/delete_xldir_simple.sh <path>
+```
+
+**Example:**
+```bash
+# Delete all directories ending with __XLDIR__ in the specified path
+./scripts/delete_xldir_simple.sh /path/to/search
+```
+
+## How It Works
+
+Both scripts use the `find` command to locate directories:
+```bash
+find "$SEARCH_PATH" -type d -name "*__XLDIR__"
+```
+
+- `-type d`: Only search for directories
+- `-name "*__XLDIR__"`: Find directories ending with `__XLDIR__`
+
+## Safety Notes
+
+⚠️ **Important Reminders:**
+- Deletion operations are irreversible, please confirm the path is correct before use
+- It's recommended to use the `--dry-run` option first to preview directories to be deleted
+- For important data, please backup first
+
+## Use Cases
+
+These scripts are typically used for cleaning up temporary directories or metadata directories in storage systems, especially in distributed storage systems where `__XLDIR__` is commonly used as a specific directory identifier.
