Question

how to set the folder's space size with C#, I want to create a new folder with the fixed size I appoint. how can I realize it?

well you cant set the size of a directory but you can set the max File size in it, its called IsolatedStorageFile here is a sample code: public double SetNewPrefsForUser() { try { byte inputChar; IsolatedStorageFile isoFile = IsolatedStorageFile.GetStore(IsolatedStorageScope.User | IsolatedStorageScope.Assembly | IsolatedStorageScope.Domain, typeof(System.Security.Policy.Url), typeof(System.Security.Policy.Url)); // If this is not a new user, archive the old preferences and // overwrite them using the new preferences. if (! this .myNewPrefs) { if (isoFile.GetDirectoryNames( "Archive" ).Length == 0) isoFile.CreateDirectory( "Archive" ); else { IsolatedStorageFileStream source = new IsolatedStorageFileStream( this .userName, FileMode.OpenOrCreate, isoFile); // This is the stream from which data will be read. Console.WriteLine( "Is the source file readable? " + (source.CanRead ? "true" : "false" )); Console.WriteLine( "Creating new IsolatedStorageFileStream for Archive." ); // Open or create a writable file. IsolatedStorageFileStream target = new IsolatedStorageFileStream( "Archive\ " + this .userName, FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write, isoFile); Console.WriteLine( "Is the target file writable? " + (target.CanWrite ? "true" : "false" )); // Stream the old file to a new file in the Archive directory. if (source.IsAsync && target.IsAsync) { // IsolatedStorageFileStreams cannot be asynchronous. However, you // can use the asynchronous BeginRead and BeginWrite functions // with some possible performance penalty. Console.WriteLine( "IsolatedStorageFileStreams cannot be asynchronous." ); } else { Console.WriteLine( "Writing data to the new file." ); while (source.Position { inputChar = (byte)source.ReadByte(); target.WriteByte(inputChar); } // Determine the size of the IsolatedStorageFileStream // by checking its Length property. Console.WriteLine( "Total Bytes Read: " + source.Length); } // After you have read and written to the streams, close them. target.Close(); source.Close(); } } // Open or create a writable file with a maximum size of 10K. IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream( this .userName, FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write, 10240, isoFile); isoStream.Position = 0; // Position to overwrite the old data. if you liked this mark it as "Accepted Answer"
