		35	; Basic concepts:
		36	; File is a FileRecord in the $MFT.
		37	; $MFT is a file, that consists of FileRecords and starts with FileRecord of itself.
		38	; FileRecord (FILE) consists of a header and attributes.
		39	; Attribute consists of a header and a body.
		40	; Attribute's body can be inside (resident) or outside of FileRecord.
		41	; File's data is a body of $Data (80h) attribute.
		42	; FileRecords is a data of the $MFT file.
		43	; Directory is a file, that consists of index nodes.
		44	; Resident index node is always located in a body of $IndexRoot (90h) attribute.
		45	; Body of $IndexAllocation (A0h) attribute is always non resident
		46	; and consists of IndexRecords.
		47	; IndexRecord (INDX) consists of a header and an index node.
		48	; Index node consists of a header and indexes.
		49	; Index consists of a header and a copy of indexed attribute's body.
		50	; Directories index $Filename (30h) attribute of all existing files.
		51	; $IndexRoot and $IndexAllocation attributes of a directory has a name — $I30.
