.sdhc files are the WWE 2K17 equivalent to PACH files. They are sub files located inside of HSPC files, and they contain various game files.
.sdhc files inside of a HSPC file are typically named using a string hash that has no logical naming pattern, however if injected into a standard PAC file they will behave the same way as a standard PACH and can be named using the classical naming schemes.
The advantage of .sdhc files appears to be greater compression than the older PACH format.
They can be opened with a number of Mod Tools including PacEditor, PacTool, and X-Packer.
.sdhc format files were first introduced to the WWE 2K Series of games with WWE 2k17.
