I have 84GB free on my Flash hard disk but in 3 hours it fills up to 0B.
When I restart the 84GB is there again and something starts eating my HDspace again.
With Grand Perspective it does not show where this space went.
In daisydisk it is in hidden space (also with administrator scan)
On About my Mac, the space went to 'Other'.
It is not the Snapshots of Time machine (I turned TM off).
This thread (What is filling up my hard drive so fast?) did not help me out, so I try again.
Thanks
Might I suggest using one of the myriad apps available at your disposal to hunt down and find the rogue files that plague you? An excellent option that I found (and free to display the content, though not to delete from within the app) would be the DaisyDisk app. It'll show you exactly what's using up your space in a relatively intuitive/futuristic display.
From there, it's a little matter of simply deleting the files in question.
You don't need special software (although there are nice options like What Size and the also-popular Daisy Disk) or to run commands in terminal to track 4 GB of change.
Apple's System Information app draws the About This Mac information that you get from Apple Menu -> About This Mac -> Storage Tab (at the top).
Click Manage for more details.
Click Review Files if the higher priority recommendations don't work or are not palatable to your use case.
Then you can know what files and buckets are the largest users of space and/or notice which buckets grow over time.
Additionally, Time Machine is very nice for telling you what files have changed if you use that tool for your backups. It would know exactly what time interval new files grew and changed since you can use a tool like BackupLoupe (or tmutil compare if you do like command line tools) to visually inspect the difference between two backup intervals to see what files used more space on your Mac.
A very low level tool to see actual writes is fs_usage but it's a bit technical and you'll need to know|learn grep or awk to reduce the output of this tool
sudo fs_usage -w
To quit the activity dump, press control C

gvb found the application that kept filling up his drive by running:
sudo fs_usage -f filesys(at my suggestion) in a Terminal. This command allows you to monitor file system usage, such as reads and writes by different processes.
In his case, "Avid App Man Helper" was filling up the drive continuously. Once this application was removed, his hard drive space was freed and no longer being continuously filled by this process.
