+# Obtain a MD5 code for every NetCDF of a folder and make their MD5 files
+
+In this example, we have used data from the [Dyfamed observatory](https://www.seanoe.org/data/00326/43749/) with key: [70639](https://www.seanoe.org/data/00326/43749/data/70639.zip). We are going to create a MD5 file for each NetCDF file in the folder
+
+```python
+import mooda as md
+import os
+
+# Make a list of file locations
+root = '/path/to/directory/'
+nc_files = [os.path.join(root, filename)
+         for root, _, filenames in os.walk(root)
+         for filename in filenames
+         if '.nc' in filename]
+
+for nc_file in nc_files:
+    print('Path:', nc_file)
+    md5_code = md.md5(nc_file)
+    print('MD5:', md5_code)
+```
+
+Output:
