Upload multiple files

[tiaandp]

Hi all
I want to know if there is a way to upload multiple files to the knime server that a user can just drag or drop.

I know you can add multiple file widgets, but it would be great if once can just select multiple files.

Hi @tiaandp,

currently this isn’t possible. I will pass your request on to development (internal ticket reference: UIEXT-81).

Kind regards
Marvin

Thanks Marvin.

Can Knime unzip a zipped folder? And read all files in the folder?

Hi @tiaandp,

yes, that it can do. Simply drag these links into your workflow:

Compress Files/Folder

Compress Files/Folder (Table)

Decompress Files

Also checkout the other nodes under IO > File Folder Utility. They may be helpful when moving files around.

Kind regards
Marvin

Request: Select multiple files or directories from File Upload widget

Hi. I’m using KNIME AP 4.3 and developing a workflow for the web portal. I want to ask the user to select a directory on their local drive (or alternatively, multiple files within the directory), and the workflow would then upload all files in the directory (or alternatively, all selected files in the directory) so the workflow can process them. The File Chooser widget looked promising, but it’s limited to selecting files or directories from a remote mountpoint. The File Upload widget allows s…

Uploading multiple files from same directory for processing

Hi, I’m trying to create a workflow that uploads and processes multiple files from the same directory that’s compatible with the KNIME server. The file upload node allows uploading a single file, but I haven’t been able to loop over each file in the directory and upload everything automatically. What’s the best way to do that? In more detail, the directory will contain a single xls file and multiple SDF’s and the info in the xls file will have to be added to the info in the SDF file, eventuall…

Hi, KNIME AP 4.6.2 KNIME Server 4.15.1 I currently try to create a component for a workflow running on a knime server based on: https://kni.me/w/xswv3kaw2K-ybXsU First Problem: I use the combination of Refresh Button and File Upload widgets to load multiple files by writing each file to a temporary folder using the CSV writer.

Local File Browser Configuration In local

Because the server doesn’t support folder upload functionality, now i am trying to ensure that configuration does the job atleast in the local machine. However the local file browser configuration also seems to support single file selection and not multiple files. The moment i select the folder and pass it to an excel reader, it doesn’t allow. Is there any way this can be achieved? The goal is that the user doesn’t get to see the logic and they only choose the folder in their local. TIA
