File IO with Kotlin multiplatform

I would like to do some basic filesystem operations on mingwX64 Windows (and possibly other platforms): open, close, read, rename, get metadata, list files in a directory.

I have found one project that promises to implement this functionality: KotlinxIO. However, there has been no progress made in years.

Are there any other alternatives or workarounds?

Solution

  • In the end, I used the library Korio. The documentation could be better, but all of the functionality I need is implemented for all platforms (Jvm, Desktop, Android, ..):

    import com.soywiz.korio.file.std.*

suspend fun main {
  val cwd = localCurrentDirVfs
  val files = cwd.list()
  cwd["Hello.txt"].open().close()
  cwd["Hello.txt"].renameTo("Hi.txt")
  val metadata = cwd["Hi.txt"].stat()
}

    On top of that, it allows usage of the same API for accessing online files, zip archives, etc. which is pretty neat.
