How to delete strings from the /FileStore/

[kkawka1]

We have just started working with databricks in one of my university modules, and the lecturers gave us a set of commands to practice saving data in the FileStore. One of the commands was the following:

dbutils .fs.cp("/ databricks - datasets / weathher / high_temps ", "/ FileStore /") 

This basically saved a bunch of strings in the FileStore without creating a new file. I have no idea how to remove them. Is this even possible?

hey @Konrad Kawka​ you can use the command dbutils.fs.rm("your_filestore_path",True)

This will try to remove the /FileStore/ itself, which is not allowed

IllegalArgumentException: /FileStore is a system directory and cannot be deleted.

Hi @Vidula Khanna​ 

Unfortunately, I was not able to resolve the issue. I am beginning to think that it simply can't be done. After running this line of code:

dbutils .fs.cp("/databricks-datasets/weathher/high_temps ", "/ FileStore /") 

the contents of the high-temps.csv were saved in the FileStore itself as a long string. I don't know how to remove it. I've noticed that I can replace what is stored in the FileStore, for example by running this line of code:

dbutils .fs.cp("/databricks-datasets/flights/departuredelays.csv ", "/ FileStore /") 

Instead of adding more data, it replaces the contents of high_temps with the contents of departuredelays.csv. What I want to do, is to remove what I accidentally saved in the FileStore. I now know how to correctly save it in a new directory within the file store. I just want to remove what was saved in the root FileStore. I even managed to replace it all with an empty string. But what I would like to know is how to get access to the FileStore, see the list of subdirectories I created, and remove any data that I saved in the root FileStore by accident. Another issue is that when I try to run:

dbutils .fs.ls("/FileStore/")

It does not show me the list of files I created, and running this:

dbutils .fs.head("/FileStore/")

Returns a long string with the contents of one of the files I accidentally saved
