It looks like we are creating a folder like like structure, but we aren't. It is a virtual file system which gives us the feeling of folder like structure but when we try to do any operations on folder level it wont effect similar to what it does in ADLS, like if we need to rename the folder in Blob storage containing 5 blobs, then we need to rename the folder name 5 times.... but in adls one time it is enough to rename the entire folder. Hope this explains better: kzfaq.info/get/bejne/ja2Uh69nmaumiKs.html
