.NET Framework System.IO.File class "Touch" a large amount of files (to update last write time)
Example
This example updates last write time of a huge number of files (using System.IO.Directory.EnumerateFiles instead of System.IO.Directory.GetFiles()). Optionally you can specify a search pattern (default is "*.*" and eventually search through a directory tree (not only the specified directory):
public static void Touch(string path,
string searchPattern = "*.*",
SearchOptions options = SearchOptions.None)
{
var now = DateTime.Now;
foreach (var filePath in Directory.EnumerateFiles(path, searchPattern, options))
{
File.SetLastWriteTime(filePath, now);
}
}
