Primal Script intermittently corrupts files during transfer

[Alexander Riedel]

Yes. I get that. We have no problem here on our side with any of this, using your files, our files or anything else. Which does not help you of course.

I have about finished all revisions on this somewhat dated code, just to make sure. But none of that would explain what you are seeing. As this started without any software changes on our side from what I can tell, I think it would be a good idea to explore some other possible culprits.

Before I get into that, rest assured that are working diligently on refactoring this code to catch more potential error situations and make it more robust. But FTP protocols are not all that complicated and built into Windows anyway.

- Can you please research what other software might have been rolled out at the time this started? My favorite interference has always been A/V software, because of, well, experience.
While normally A/V software makes files completely disappear if considered harmful, it can happen that some of these tools forcibly close files, open them exclusively and scan a file
while it is still being written. So if you could check that, that would help.

- In order to exclude your FTP server as the problem, I would like to setup a time where I give you access to our FTP test server and run some tests with that.
That would tell us if this happens on your machine or on your server. I know that you have multiple machines sharing this problem, but I would assume they are in one network and
similarly configured. In order to do that, please let me know what time zone you are in and when it would be convenient for you. It shouldn't take longer than a few minutes.

- If you can, maybe you can fire up a generic VM in your environment, Windows 10 or 11 with NO additional software but PrimalScript. See if transferring data to and from that to your FTP
server shows the same issues or not. That would for sure determine if something local and common on your machines interferes.

Thank you for your patience.

I will have our network team check out our side for software changes/upgrades/etc.
I will also see if they can set up a different FTP test like you suggested and see what happens.
We will get back to you.

Hello again. We seem to have FTP working again.
While we are not 100% sure the reason, we had upgraded our security software (ThreatLocker).
We have determined this was the cause of our FTP issues. We will continue to monitor on our end.
We would like to thank you for all your help in working with us.

Thank you for letting us know. Please make sure to update to the latest build and let us know if the latest improvements from our side work for you.
