Does MT5 VPS Experts-only resynchronization preserve Hosted MQL5/Files?

[hrshakeri]

Hello,

Before resynchronizing my MT5 Virtual Hosting subscription, I need to confirm whether existing runtime-generated files in the Hosted MQL5/Files directory are preserved.

My EA uses two A/B state files created with FileOpen() without FILE_COMMON. They are not declared with #property tester_file.

Does Experts-only resynchronization preserve these files, or can it delete or overwrite them with local files?

Is there an officially supported way to back up Hosted runtime files before migration?

I need confirmation before updating EA inputs because these files contain critical recovery and risk state.

Thank you.

First, read the online VPS help , there is also a video.

To transfer your own files to MetaTrader VPS, you need to specify the propert compiler in the code. It requires a certain level of ownership of the subject.

To transfer a file to a hosting server (as well as a tester agent), you need to use the directive

#property tester_file "<file_name>"

Practical example with #property tester_file - post #21

That is why some people are asking the sellers in the Market: "Is your EA adapted to be used in MQL5 VPS or not?".
