Could Not Save Workflow - Urgent

Hi, if anyone can help it would be appreciated. I keep getting errors like this when trying to save workflows. Usually this happens after a period of absence from the computer, there is just no way to save the workflow, and neither does it allow you to save as a different name, publish to Server, or export. This is particularly a concern when changes have been made and there simply is no way to know what those changes are and whether they will be saved or not. Please advise? [image] [image] …

"File access problems": Cannot save workflow

Hello, My hard disk was getting low on space during running a workflow. I then went to delete all accessible files from the Users/AppData/Local/Temp folder while the workflow was still running. Now the result is that I am unable to save the workflow and receive the following message: File access problems: C:\Users…\AppData\Local\Temp\knime…\knime_container…8.bin.snappy (The system cannot find the path specified) Have I permanently lost my most recent changes to the worklow?

Also, you can try changing the compression to (GZIP or NONE) by passing the value to the parameter -Dknime.compress.io in your knime.ini file as described below.

Disk Storage

KNIME compresses tables written to disk to reduce the amount of occupied disk space. By default, KNIME uses the Snappy compression algorithm to compress its tables. However, KNIME can be configured to use GZIP compression or no compression scheme at all via the -Dknime.compress.io parameter in the knime.ini file.
