This application can be used for running various operations on the contents of a .ccd file, which is used by Harry Potter: Quidditch World Cup. This tool currently supports extracting archives, compressing folders and recursive text search among game archives.
RefPack implementation from OpenSAGE project is used for dealing with the compressed streams: https://github.com/OpenSAGE/OpenSAGE
The compression algorithm is based on the original file by KUDr (original SVN is no longer available).
- Mono.Options (available via Nuget)

File section deserves a special mention as the contents of this region are compressed with RefPack. This streams needs to be deflated before files can be extracted according to the header data above. Unlike most RefPack streams from other EA game archives, first-byte of the CCD streams (normally reserved for flags) are always set to 0x15. This is followed by the standard magic number 0xFB. The proceeding archive length is always 4-bytes long, regardless of the first byte of the archive stream. It's also noteworthy that compression uses a reference window size of 0x4000, unlike other games that generally seem to use 0x8000. Using the default value of 0x8000 will cause QWC to crash upon parsing the archive.
Compress folder Gryff and its content to Gryff.ccd:
QWCArchiveTool.exe -c "Gryff" -o ".\Gryff.ccd "
Extract Gryff.ccd to and place contents in ..\OutputDir\Gryff:
QWCArchiveTool.exe -e "C:\Files\Gryff.ccd" -o ..\OutputDir
Search for string "snitch" in all cli files within game archives:
QWCArchiveTool.exe -s "snitch"
If game directory option is omitted, the location will be retrieved from Registry.
