Question

I want to load a directory in actionscript. To do that I use the File class but sadly it doesn’t work.

Here is what I did. First I created the directory in the applicationStorageDirectory using this code:

var root:File = File.applicationStorageDirectory.resolvePath(UIDUtil.createUID());
root.createDirectory();

After that I dispatch an event so that the application copies some files into that folder. To do that I use the method File.copyToAsync (that works, so this is not the problem). When all files are copied to that directory I try to load that directory using the File call again. The reason I want to do that is, that I need the content/data as a byte array. The data property of the File class is only set when the load method is called successfully before.

Since the directory is in the application storage directory (the url property of the file object has this content: app-storage:/FF011DBC-2E92-46A8-D5F8-29FE1DD8FA7A) I thought just calling the load method would work. I was wrong… Although the documentation of that method says I can just call that method when the application runs in AIR and the file to load is inside the application sandbox, I get the following error:

Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.
at flash.filesystem::File/resolveComponents()
at flash.filesystem::File/resolvePath()
    ...

Do you have any ideas what could be wrong? Is it even possible to load a directory using the File class? Or does that error occur because the isDirectory flag is set to true in the file object?

kind regards

I believe a File, when pointing to a directory, does not contains the data of the files contained inside it. You would have to use File.getDirectoryListing() to loop over all files the folder, and append their bytes to the ZIP archive separately. Don’t forget to check if you come across sub-directory…

You can check this link for an example of how to do this.
