Saving files in Application directory?

[ares623]

how do I save a file into the application install directory, so that I can open/load it again after the app is closed?
I mean, where do I save it during debugging and releasing?

Hi,

There are a number of directories you can access using the File class in AIR. Check out this documentation for more info. --> http://livedocs.adobe.com/flash/9.0/Act ... /File.html

Basically there's the applicationDirectory, applicationStorageDirectory, desktopDirectory, and documentsDirectory. These will trace out to the OS specific directories.

Good luck!

Just to let you know you can not write a file to the application directory. This is a security feature adobe put in. Instead use the ApplicationStorageDirectory if you do not want your user seeing the files created. If you want them to see the files however I would suggest the documentsDirectory or give the user the option to choose the location using a save dialog box.

Location of the applicationStorageDirectory for Windows XP: C:\Documents and Settings\(User)\Application Data\(Applcation Folder)

thanks!
but i'm having trouble writing to the file..

here is my code

Code: Select all

var saveFile:File = File.applicationStorageDirectory;
saveFile.resolvePath("colors.txt");

trace(saveFile.exists); //traces 'true'

var writer:FileStream = new FileStream();
writer.open(saveFile, FileMode.WRITE);  //error here


I get a "Error #3006: Not a file." error..

Haha I was writing a post saying I didnt know why you were getting that error but then it hit me. What wouldnt be a file ... A folder! That is what it is doing it is trying to open the folder as a file and clearly this wont do. Corrected code below.

Code: Select all

saveFile = saveFile.resolvePath("colors.txt");


Though may I suggest that you combine lines 1 and 2 into one line. It should look like this.

Code: Select all

var saveFile:File = File.applicationStorageDirectory.resolvePath("colors.txt");


Well good luck

Now I have another problem..
When my app starts, it reads from the file I created.. no problem there.
After reading, I close the file by calling

Code: Select all

fileStream.close()

When my app closes, I try to overwrite my file. I get a "Error #3013: File or directory is in use."

Code: Select all

var saveFile:File = File.documentsDirectory;
saveFile = saveFile.resolvePath("colors.txt");
fileStream.open(saveFile, FileMode.WRITE);


But I've already closed the file.. I've tried closing the filestream again before opening for writing (closing it twice). I've also tried reinstantiating the FileStream instance. Still not working.

seems to be working now.. don't know what happened.

Any idea why this started working for you again? I am running into the same problem. Weird thing is that it happens even when I restart my app. It's gotta be something in my routine logic (where I am reading the file and for some reason it isn't closing its stream...)

Thanks.

ares623: I'd also be interested if you figure out why this started working. I'm also getting error 3013 and tried the things you tried. I'm not having the same issue as ebrentnelson with it happening when I restart the app.

I am doing openAsync and writeUTFBytes, I see the OUTPUT_PROGRESS and CLOSE event is being thrown but if I try to resave the file I get 3013.
