# How to: Copy Files with a Specific Pattern to a Directory in Visual Basic

The GetFiles method returns a read-only collection of strings representing the path names for the files. You can use the wildCards parameter to specify a specific pattern.

An empty collection is returned if no matching files are found.

You can use the CopyFile method to copy the files to a directory.

### To copy files with a specific pattern to a directory

1. Use the GetFiles method to return the list of files. This example returns all .rtf files in the specified directory.

For Each foundFile As String In My.Computer.FileSystem.GetFiles(
My.Computer.FileSystem.SpecialDirectories.MyDocuments,
Microsoft.VisualBasic.FileIO.SearchOption.SearchTopLevelOnly, "*.rtf")

2. Use the CopyFile method to copy the files. This example copies the files to the directory named testdirectory.

My.Computer.FileSystem.CopyFile(foundFile, "C:\testdirectory\" & My.Computer.FileSystem.GetName(foundFile))

3. Close the For statement with a Next statement.
