FME Workbench unable to write to Temp folder

Hi @joe.fme​ I wonder if this could be that there is not enough space in your temp location. You could try following the directions in this article to set a temporary file location for FME to use via the FME_TEMP environment variable and see how that goes for you.

Hi Jenna,

Unfortunately I've tried both the E drive (where the FME_Temp environment variable points to) and C:/Temp but with no joy.

It's baffling, as we have scheduled tasks that are running fine. I'm able to clear the temp folders and have permissions on this particular server running Workbench.

Knowing my luck it's something I'm missing but I've thought of every possibility so far.

I got a bit further just copying and pasting the workspace reader/transformers into a new workspace, but it still threw an error about 80% of the way through (whereas before it was when it was about 30% done)

Edit - the C:\\temp issue persists

Hi Jenna, again, I've tried rebuilding the model, reading in the source data for the joins and the Temp environment variable being changed to another drive but no luck. It just seems to be this 1 workbench as well, as the others (thankfully) work fine.

Proper stumped - any input/ideas/spitball something would be much appreciated. Just all boils down to the Temp folder -

FFS writer: Failed to write to file 'E:\\temp\\wbrun_1685710463911_61604\\fmetmp_7\\FMETable\\FeatureJoiner_1685713198917_56908.fts'. Please ensure that you have sufficient privileges to write this file, and that sufficient disk space is available

120GB free and admin permissions :(

Were you able to find a solution to this problem? I’m currently having this issue with the FileDeleter transformer. We just upgraded to 2025.0 from 2023.2.4 and am now seeing issues.

​@joe.fme 

Did you try running the workspace step by step? (run to this)

Meaning up till the first transformer and so on to figure the root cause?
