B4J Question file.dirapp permission error

[Douglas Farias]

    target = File.DirApp
    File.MakeDir(target, "Arquivos_Recebidos")
    fp = File.Combine(target,"Arquivos_Recebidos" )

i made this code to make a folder of my .jar
my .jar receiv files from the android and store this file on this folder.

but i dont understand why i have permission error when i try save itens on this folder
if i dont use fp this works only file.dirapp but if i use file.dirapp & "Arquivos_Recebidos" = fp
i have this error log

why this?
how can i make a fixed folder to save my files under the pc? i want to save this in a folder.
thx

 

[Erel]

Do you see this folder in Windows Explorer?

 

[Douglas Farias]

yes i can open

C:\Users\Douglas\Desktop\MEUSAP~1\EMDESE~1\ABOOPC~1\pc\Objects\Arquivos_Recebidos

is the file.dirapp with only a folder, its possible store files in a folder on file.dirapp?
the error is permission, but where i add permission at b4j?

 

[Erel]

You cannot add permissions in Windows. My guess is that this error is related to a non-ascii character in the path which breaks something in the Java file handling.

Try to save your file in c:\test.

@Erel have this error log

File.Copy(astreamO.TempFolder, fileName, "c:\test", Key.SubString(8))

[Erel]

Now I understand. You are trying to open a folder instead of a file. Key.SubString(8) returns an empty string.
