How to check if a file exists with the QT Installer Framework?

[narae]

I want to check file exist.

I created folder: %temp%\test (C:\Users\me\AppData\Local\Temp\test)
I copied README2.txt to the folder.

And if there the file in the folder, I want to copy them to TargetDir.

So I did it like the code below.

if(installer.fileExists("@InstallerDirPath@/README2.txt")){
            console.log("Find File");
            component.addOperation("Copy", "@InstallerDirPath@/README2.txt", "@TargetDir@/README2.txt");
}
else
            console.log("Can't Find File");

InstallerDirPath: The directory that contains the installer application executable.

However, even if there is a README2.txt file in the folder, the file cannot be found.

How can I check if the file exists and copy the file?

You can try use

var files = QDesktopServices.findFiles("@InstallerDirPath@", "README2.txt");
