I want to add a tag to the file attributes, this file is used to certification only (the file name and file content will change, also will become the md5), think of attribute data in the file, which is marked in the metadata, consult operation method,
The find method with c #, there has been no research to understand, is as follows:

Your problem, involves the provisions of the system of file attributes, file attributes, in general, can not violate the provisions of the operating system,
If the file is your own, can set up a file header, internal write attributes,
If is public files, you generally can't be modified, you can only analyze the file, find the class file binary blank areas, binary address index order of blank, write specific property data,

File metadata manager seems to modify the terms of the system, you can add attributes to various files, so that you can achieve the anticipated goal

The landlord to provide the address of the program source code and documentation, is c #, you can reference, the program can be of various add metadata file, but only for NTFS system, if the file is moved to the FAT system or sent as email attachments will lose this information, making can find some pictures of Delphi, speaking, reading and writing on the exif information source, such as https://github.com/esmondb/ccr-exif, a add attributes, one is written to the value, but are associated with the metadata,
