Hi..
dont use the TDes8 as it is..
you can use a TBuf8 instead.
try this

Code:

TBuf8<50>aDes;
file.Read(aDes);

if your file contains some large amount of data,you can use a HBufC8 object instead of Tbuf8.

Hi,
you can create a directory using

Quote

fs.MkDir(_L("\\system\\apps\\your appname\\"));

and your file path should be

Quote

_LIT(KFileName, "\\system\\apps\\your appname\\test.txt");

hope this help you

I able to write text into file by using this code

Quote

_LIT(KFileName, "c:\\test.txt");
_LIT8(KData, "A1=12345&");

//...

RFs fs;
fs.Connect();
CleanupClosePushL(fs);

RFile file;
TInt err = file.Open(fs, KFileName, EFileShareAny | EFileWrite);
if(err != KErrNone)
{
   err = file.Create(fs, KFileName, EFileShareAny | EFileWrite);
}
if (!err)
{
   CleanupClosePushL(file);

   User::LeaveIfError(file.Write(KData));

   CleanupStack::PopAndDestroy(); // file
}
CleanupStack::PopAndDestroy(); // fs

but that comes in winscw\c path. (as I use 7.0 and 2nd sdk) I also did armi build but no such file is created in another folder.

So what should be done to create file in real device. I mean what should be the path for that. (currently my path is _LIT(KFileName, "c:\\test.txt"); )
