I've always used xui.defaultfolder to place temporary files there.
I also put exe files (ffmpeg, 7z) there to use them from my b4j application. I even do mergers with sound and image files.
Everything still works without crashes.
The advantage of this folder is that it is on any PC

Dim appname As String = "AWESOMEAPP"
    xui.SetDataFolder(appname)
    xui.DefaultFolder(appname)

This defaults to the location (appdata/roaming/appname). You dont need to set the path yourself as you did

xui.DefaultFolder ( c:/"user"/appdata/roaming/"appname"/ )

Actually this is a solution for every OS supported by B4X (Windows, linux, etc)
You don't mess with special permissions of folders too..

For example if you want to save at windows root c:\ you must run app as admin... is a windows forbition
