Databricks upon inserting delta table data inserts into folders in Dev

NandaKishoreI

We have a Delta Table in Databricks. When we are inserting data into the Delta Table, in the storage account, it creates folders like: 05, 0H, 0F, 0O, 1T,1W, etc... and adds the parquet files there.

We have not defined any partitions. We are inserting data using following code:

df.write\
                    .mode('append')\
                    .option("mergeSchema", "true")\
                    .option("ignoreLeadingWhiteSpace","false") \
                    .option("ignoreTrailingWhiteSpace","false") \
                    .format('delta').save(prepped_path)
 
The Table Properties are:
delta.columnMapping.mode=name
delta.minReaderVersion=2
delta.minWriterVersion=6
delta.columnMapping.maxColumnId=18
