How to clear temp data from dataflow / nifi?

[#1]

I noticed that the disk drive on my HDF server is almost full.

I did some exploring, and found that the nifi/content_repository folder has 1.4TB of data in it, even with nothing in any queue, and nifi stopped.

I have had nifi.flow.configuration.archive.enable=false in nifi/conf/nifi.properties (since I installed), but I see a whole folder full of data with today's date.

The data in the content_repository folder is thousands of folders, named numerically ("1", "2", etc). Each folder has a single file named with an epoch timestamp.

Can someone give me some guidance on what I can safely delete and how to keep this tool from eating up so much disk storage?

Ah! I see that there are 2 "archive" properties in the nifi.properties file:

nifi.flow.configuration.archive.enabled

nifi.content.repository.archive.enabled

I was setting the former, but I need to set the latter.
