Hello @PauloHenne

Did you specify the file location in Read csv operator parameters window? Can you post your process here? You can export the process by clicking FILE --> Export process and attach it here.

Hello @PauloHenne

I don't see a read CSV operator in this process. There is a retrieve operator that will fetch data that is imported into rapidminer repository.

Are you sure this is the correct process you are facing issue with?

Hello @PauloHenne

Data loading into a repository and Read CSV are two different options. Read CSV is used to directly access data from your hard drive whereas data loading into repository will create a copy of your csv data into rapidminer format and store it in rapidminer user folders. For read CSV you are not needed to connect the "inp" and "fil" ports, you can remove that. Then you can see an option in read CSV parameters window related to file locations (csv file), this is where you need to specify where the file is located in your hard drive.
