[wix-users] How do I handle SetupFilesCleanup and SetupFiles Extract in Wix

[Tobias S]

think for the support file thing there is some news in WiX 4.x series:

## WixBuild: Version 4.0.3729.0
...
* @barnson: Adding some useful WcaUtil functions from FireGiant.
  * Add QuietExecCapture to get process output as a string.
  * Add WcaExtractBinaryToBuffer, WcaExtractBinaryToFile, and
WcaExtractBinaryToString to extract content from the Binary table.


but for others: Yes if that is required unfortunately CA is necessary IMHO
