 ## Loading Files & Databases
 
-### Loading a file headlessly
+!!! note "Headless Usage"
+    Headless file loading requires Binary Ninja Commercial or Enterprise. This feature is not available in the Personal edition.
 
-The `load` function is the recommended way to open a file for analysis in a headless script:
+### Basic file loading
 
 ```python
 from binaryninja import load
 
-# Basic usage - automatically runs analysis
+# Using context manager (recommended)
+with load('/bin/ls') as bv:
+    if bv is not None:
+        print(f"{bv.arch.name}: {hex(bv.entry_point)}")
+
+# Without context manager - must close manually
 bv = load('/bin/ls')
 if bv is not None:
-    # Do something with the binary view
     print(f"Loaded {bv.file.filename}")
-    print(f"Architecture: {bv.arch.name}")
-    print(f"Entry point: {hex(bv.entry_point)}")
-    
-    # Important: Close the file when done to prevent memory leaks
-    bv.file.close()
+    bv.file.close()  # Important: prevents memory leaks
 ```
 
-### Loading a file with options
-
-You can customize the loading behavior by passing options:
+### Loading with options
 
 ```python
 from binaryninja import load
 
-# Load with custom options
 bv = load('/bin/ls', options={
     'loader.imageBase': 0xfffffff0000,
     'loader.macho.processFunctionStarts': False,
-    'analysis.mode': 'basic',
-    'analysis.linearSweep.autorun': False
+    'analysis.mode': 'basic'
 })
-
-if bv is not None:
-    # Process the binary view
-    print(f"Loaded at base address: {hex(bv.start)}")
-    bv.file.close()
 ```
 
-### Loading a database file
-
-Binary Ninja database files (.bndb) can be loaded the same way as regular binaries:
+### Loading a database
 
 ```python
 from binaryninja import load
 
-# Load a saved database
+# .bndb files use the same API
 bv = load('/path/to/analysis.bndb')
-if bv is not None:
-    # All previous analysis is preserved
-    print(f"Loaded database with {len(bv.functions)} functions")
-    bv.file.close()
 ```
 
-### Using the context manager pattern
-
-The recommended way to work with Binary Ninja files is using a context manager, which automatically handles cleanup:
-
-```python
-from binaryninja import load
-
-# Context manager automatically closes the file
-with load('/bin/ls') as bv:
-    if bv is not None:
-        for func in bv.functions:
-            print(f"{hex(func.start)}: {func.name}")
-# File is automatically closed here
-```
-
-### Controlling analysis behavior
-
-By default, `load()` runs analysis automatically. You can disable this for faster loading:
+### Controlling analysis
 
 ```python
 from binaryninja import load
 
 # Load without running analysis
 bv = load('/bin/ls', update_analysis=False)
 if bv is not None:
-    # Manually control when analysis runs
-    bv.update_analysis_and_wait()
+    bv.update_analysis_and_wait()  # Run analysis manually
     bv.file.close()
 ```
