You mean, people are applying their own mods?

You should use https://wiki.multitheftauto.com/wiki/DownloadFile instead of triggerLatentClientEvent.

To let the system check if the file is validated.

If you use triggerLatentClientEvent you can check if the filesize has chanced, but you won't be able to check the timestamp of the creation/edit time. Only mta can do that, so it a risk.

Im use downloadFile for download resource. It is download first important scripts after other scripts.

So, is downloadFile already check it?

Read original files and store hash of their content somewhere

Then when checking if client has files,if he has, read those files that client has and turn the content into hash and compare this hash with your stored one. If hashes are different, client has tried to load his own mod.

From downloadFile wiki page:

If the file has been previously downloaded and the CRC matches, the file will not be downloaded again but onClientFileDownloadComplete will still run.

In other words: downloadFile will only download the file if the file doesn't exist, or if the file exists and the content of the file does not match the content of the file you want to download.
