	Create	Overloaded. Creates a file in the specified path.
	CreateText	Creates or opens a file for writing UTF-8 encoded text.
	Decrypt	Decrypts a file that was encrypted by the current account using the Encrypt method.
	Delete	Deletes the specified file. An exception is not thrown if the specified file does not exist.
	Encrypt	Encrypts a file so that only the account used to encrypt the file can decrypt it.
	Equals	Overloaded. Determines whether two Object instances are equal. (Inherited from Object.)
	Exists	Determines whether the specified file exists.
	GetAccessControl	Overloaded. Gets a FileSecurity object that encapsulates the access control list (ACL) entries for a specified file.
	GetAttributes	Gets the FileAttributes of the file on the path.
	GetCreationTime	Returns the creation date and time of the specified file or directory.
	GetCreationTimeUtc	Returns the creation date and time, in coordinated universal time (UTC), of the specified file or directory.
	GetHashCode	Serves as a hash function for a particular type. GetHashCode is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object.)
	GetLastAccessTime	Returns the date and time the specified file or directory was last accessed.
	GetLastAccessTimeUtc	Returns the date and time, in coordinated universal time (UTC), that the specified file or directory was last accessed.
	GetLastWriteTime	Returns the date and time the specified file or directory was last written to.
	GetLastWriteTimeUtc	Returns the date and time, in coordinated universal time (UTC), that the specified file or directory was last written to.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Move	Moves a specified file to a new location, providing the option to specify a new file name.
	Open	Overloaded. Opens a FileStream on the specified path.
	OpenRead	Opens an existing file for reading.
	OpenText	Opens an existing UTF-8 encoded text file for reading.
	OpenWrite	Opens an existing file for writing.
	ReadAllBytes	Opens a binary file, reads the contents of the file into a byte array, and then closes the file.
	ReadAllLines	Overloaded. Opens a text file, reads all lines of the file into a string array, and then closes the file.
	ReadAllText	Overloaded. Opens a text file, reads all lines of the file into a string, and then closes the file.
	ReferenceEquals	Determines whether the specified Object instances are the same instance. (Inherited from Object.)

	SetAccessControl	Applies access control list (ACL) entries described by a FileSecurity object to the specified file.
	SetAttributes	Sets the specified FileAttributes of the file on the specified path.
	SetCreationTime	Sets the date and time the file was created.
	SetCreationTimeUtc	Sets the date and time, in coordinated universal time (UTC), that the file was created.
	SetLastAccessTime	Sets the date and time the specified file was last accessed.
	SetLastAccessTimeUtc	Sets the date and time, in coordinated universal time (UTC), that the specified file was last accessed.
	SetLastWriteTime	Sets the date and time that the specified file was last written to.
	SetLastWriteTimeUtc	Sets the date and time, in coordinated universal time (UTC), that the specified file was last written to.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)
	WriteAllBytes	Creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.
	WriteAllLines	Overloaded. Creates a new file, writes the specified string to the file, and then closes the file. If the target file already exists, it is overwritten.
