Hello,
i added multiple lakehouses toone notebook.
Now i want to check what is the latest file in a specific folder in each of the lakehouses.
I'm able to access the data using the 'File API path' of the default Lakehouse:
list_of_files = glob.glob('/lakehouse/default/Files/.../input/*')
last_modified_file = max(list_of_files, key=os.path.getmtime)
last_modified_file
However when i try to do the same with ABFS Path, i dont get a result in list_of_files. It just returns an empty list:
list_of_files = glob.glob('abfss://.../input/*')
list_of_files
If i try to read data with the ABFS Path i works without any issue- so i can not be an issue with path/permission:
df = pd.read_csv('abfss://...input/example.csv',sheet_name="Tabelle1")
Any idea how to make it work that not only the default lakehouse can be accessed but also another as datasource added lakehouses?

Hi @BoSe ,
Thanks for using Fabric Community.
It looks like glob is not able to process it when we are passing the abfs path. This looks like a limitation with glob.
You can also try mssparkutils.fs.ls - Introduction to Microsoft Spark utilities - Azure Synapse Analytics | Microsoft Learn
files = mssparkutils.fs.ls("abfss://5e****dd/Files")
file_paths = [f.path for f in files]
print(file_path)
Hope this is helpful. Please let me know incase of further queries.

latest_file = max(files, key=lambda file: file.modifyTime)
Thanks for the input.
You get the path.. but it does not work with abfss path
