Question

I am saving images and files to Environment.SpecialFolder.Personal. Saving a file is easy, but how does one delete a file?

I wish to delete files that my program considers old, so that I save as much space as possible.

I am using Monotouch to develop an iPhone application, but I believe this can apply to generic .NET programs as well.

Answer 1

  File.Delete ( filename );

Where filename is Path.Combine( Environment.GetFolderPath ( Environment.SpecialFolder.Personal ), "TODELETE.ext" );

Using Directory.GetFiles () you can get all the files of the folder.
Than get a FileInfo object from each to figure out size, creation date, etc.
Delete whatever you consider old enough.
