   @raphinesse Thank you so much, I really appreciate it :)
   
   I am also a little bit worried about changing the behaviour of `FileWriter` to always use chunks, because it can potentially give problems with partial writes. Writing to a file feels to me like something that should be atomic, if possible.
   
   This makes me unsure about if or how to continue https://github.com/apache/cordova-plugin-file/pull/461
   
   Would it be reasonable to provide a `ChunkedFileWriter` ( And maybe a `ChunkedFileReader` )? It could implement the chunked writing behaviour on top of `FileWriter`.
   
   Something like 
   
   ```
   fileEntry.createWriter(async (fileWriter) => {
       var chunkedWriter = new ChunkedFileWriter(fileWriter)
       chunkedWriter.setChunkSize(2 ** 15)
   
       chunkedWriter.onwriteend = function()
       ...
                     
   ```
