UPDATE: The error was not any hidden files in FMECloud - but rather that the process using AzureFileStorageConnector downloaded a whole FOLDER instead of individual files. So instead of downloading a file of size 0,5 GB - it downloaded all the files in that folder (50GB). Havent figured out why yet, but might be something between the screen and the person sitting in front of the computer.
I have a FMECloud instance with 100GB Primary disk, and it seems according to the Dashboard that 97GB is in use. I can only find roughly 60GB in the DATA-folder. And FME Cloud seems to run the cleanup. So i wonder where the missing 40GB of data is. The projects uses a lot of raster-data, so I wonder if they are cached somewhere, or if the FFS is somewhere. But cant seem to figure out what to empty.
Moving to a larger instance might be a solution, but Backup 100 GB, download, start new instance 200 GB and restore takes some time....
Would be GREAT to be able to RESIZE the PRIMARY and Secondary disk of FMECloud
