MOV		QuickTime movie file
.MOV files have a complicated file signature. The string "moov" is the most common but I have also seen: 0x66-72-65-65 free 0x6D-64-61-74 mdat 0x77-69-64-65 wide And the following have been reported to me: 0x70-6E-6F-74 pnot 0x73-6B-69-70 skip Furthermore, if you look at byte position xxxxxxxx+4 (where xxxxxxxx is bytes 0-3 of the header), you will find one (or more!) of these strings repeated; the string "free" seems to be the most common. For more information, see the QuickTime File Format page. (Thanks to D. Wright for getting me started on this!)

[See also Excel, Outlook, PowerPoint, and Word "subheaders" at byte offset 512 (0x200).] There appear to several subheader formats and a dearth of documentation. There have been reports that there are different subheaders for Windows and Mac versions of MS Office but I cannot confirm that.] Password-protected DOCX, XLSX, and PPTX files also use this signature those files are saved as OLECF files. [Note the similarity between D0 CF 11 E0 and the word "docfile"!]

NOTES on JPEG file headers: The proper JPEG header is the two-byte sequence, 0xFF-D8, aka Start of Image (SOI) marker. JPEG files end with the two-byte sequence, 0xFF-D9, aka End of Image (EOI) marker. Between the SOI and EOI, JPEG files are composed of segments. Segments start with a two-byte Segment Tag followed by a two-byte Segment Length field and then a zero-terminated string identifier (i.e., a character string followed by a 0x00), as shown below with the JFIF, Exif, and SPIFF segments. Segment Tags of the form 0x-FF-Ex (where x = 0..F) are referred to as APP0-APP15, and contain application-specific information. The most commonly seen APP segments at the beginning of a JPEG file are APP0 and APP1 although others are also seen. Some additional tags are shown below: 0xFF-D8-FF-E0 — Standard JPEG/JFIF file, as shown below. 0xFF-D8-FF-E1 — Standard JPEG file with Exif metadata, as shown below. 0xFF-D8-FF-E2 — Canon Camera Image File Format (CIFF) JPEG file (formerly used by some EOS and Powershot cameras). 0xFF-D8-FF-E8 — Still Picture Interchange File Format (SPIFF), as shown below.
