3 years ago I created the following project and included your sample code: https://github.com/omicronapps/compressFile
I modified this to compress some byte arrays into a Zip archive and this works fine. Can you modify this source code sample to reproduce the issue? Then please be sure to create a pull request with the changes.
Also see here for instructions on how to create an archive with any format supported by 7-Zip: http://sevenzipjbind.sourceforge.net/compression_snippets.html#create-generic

this is my code , when i compress a dir , updateProgress stops at 38% and dir has no files .
` open inner class MyCreateCallback : IOutCreateCallback {
private var fileComplete = 0
override fun setTotal(total: Long) {
setTotalProgress(total)
}
`
` fun compressFile( itemCount: Int, outputPath: String, archiveFormat: ArchiveFormat, callback: IOutCreateCallback
) {
val path = File(outputPath)
var success: Boolean
var raf: RandomAccessFile? = null
var outArchive: IOutCreateArchive? = null
