The code runs on several platforms like Windows and Linux. This is valid only for object files. Universe Sky Star. Background. This flag is obsolete and is replaced by IMAGE_SCN_ALIGN_1BYTES. If this value is less than the VirtualSize member, the remainder of the section is filled with zeroes. File headers are used to identify a file by examining the first 4 or 5 bytes of its hexadecimal content. Align data on a 8-byte boundary. This value must be a multiple of the FileAlignment member of the Public Type IMAGE_FILE_HEADER ' The target CPU for this executable. This is done so that code can be broken down into separate files for modularity. I had a lot of images of different types with lost file extensions and no other way of classifying them.
