max90, use the following command line to compress your files into one archive:
You must have NanoZip on your FreeArc bin folder.
arc a archive.arc source_files -mmaxprecompj+srep:m5f:a1+delta+nz:cc:m1.88g -di
For uncompression, use the following command line:
Just add the last command line to your setup program and you will be fine. FreeArc will decompress all files included in the compression chain, including the SREP file and, when done, destination_folder will have all your files decompressed.
arc x archive.arc -dpdestination_folder
PS. If you find very slow NanoZip decompression, change nz:cc:m1.88g with nz:cO:m1.85g .
