Report if file is HFS+ compressed:                        afsctool [-v] file
Report if folder contains HFS+ compressed files:          afsctool [-fvvi] [-t <ContentType/Extension>] folder
List HFS+ compressed files in folder:                     afsctool -l[fvv] folder
Decompress HFS+ compressed file or folder:                afsctool -d[i] [-t <ContentType>] file/folder
Create archive file with compressed data in data fork:    afsctool -a[d] src dst
Extract HFS+ compression archive to file:                 afsctool -x[d] src dst
Apply HFS+ compression to file or folder:                 afsctool -c[nlfvvi] [-<level>] [-m <size>] [-s <percentage>] [-t <ContentType>] file/folder

Options:
-v Increase verbosity level
-f Detect hard links
-l List files that are HFS+ compressed (or if the -c option is given, files which fail to compress)
-L Allow large compressed blocks (not recommended)
-n Do not verify files after compression (not recommended)
-m <size> Largest file size to compress, in bytes
-s <percentage> For compression to be applied, compression savings must be at least this percentage
-t <ContentType/Extension> Return statistics for files of given content type and when compressing,
                           if this option is given then only files of content type(s) or extension(s) specified with this option will be compressed
-i Compress or show statistics for files that don't have content type(s) or extension(s) given by -t <ContentType/Extension> instead of those that do
-<level> Compression level to use when compressing (ranging from 1 to 9, with 1 being the fastest and 9 being the best - default is 5)
