_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.

dont use the TDes8 as it is..
you can use a TBuf8 instead.
try this
file.Read(aDes);
if your file contains some large amount of data,you can use a HBufC8 object instead of Tbuf8.
