Uint32 SizeRIFF // 4 byte file size, little-endian order This files are vector designs created in CorelDraw. Uint32 SignatureRIFF // Signature: "RIFF" When inspecting sample.cdr file's data using any Hex Viewer, like Disk Editor, which is included in File Recovery package, we can see it starts with a signature RIFF (hex: 52, 49, 46, 46).Īt offset 8 there is a signature of CorelDRAW Drawing RIFF Type CDR9 (hex: 43, 44, 52, 39), which means CDR file's version is 9.Īt offset 4 there is a data size: 20,088 (hex: 78, 4E, 00, 00) in little-endian order (low byte first).Īdding header length to the data size, we calculate a total CDR file size: 20,088 + 8 = 20,096. Summarizing size for all found chunks, we calculate total file size. The version number of the writing program in hexadecimal ("4" meaning version 4, "D" meaning version 14).Ĭhunk size is data size plus 8 bytes. Each segment is prefixed with an 12 byte header:Ĥ byte signature ( RIFF), 4 byte data size (little-endian order, low byte first) andĪsterisk "*" being in early versions just a blank, and beginning with Corel Draw 4, RIFF files are organized into data segments (chunks). From version X4 (14) on, the CDR file is a ZIP-compressed directory of several files, among them XML-files and the RIFF-structured files.Īny RIFF container, including CDR drawing must have a signature (tag) RIFF (hex: 52 49 46 46) at the beginning of the file. ![]() The actual data chunk of the RIFF remains a Corel proprietary format. Starting with CorelDRAW 3, the file format changed to a Resource Interchange File Format (RIFF) envelope, recognizable by the first four bytes of the file being "RIFF", and a "CDR*vrsn" in bytes 9 to 15, with the asterisk "*" being in early versions just a blank, and beginning with Corel Draw 4, the version number of the writing program in hexadecimal ("4" meaning version 4, "D" meaning version 14). ![]() In its first versions, the CDR file format was a completely proprietary Corel file format primarily used for vector graphic drawings and developed by Corel Corp., recognizable by the first two bytes of the file being "WL". Developed by the software maker Corel, the format is a vector image, usually created using the.
