We use the following archiving formats. Search the pub/cbm/archiving subdirectory for appropriate utilities to extract some of these. For information on the major archiving formats, refer to the file /README.FILETYPES or http://www.funet.fi/ftp/README.FILETYPES.

See /ftp/README.FILETYPES where to get it for your system. If you are using FTP, you can also omit the .gz or .Z suffix to get the file uncompressed on the fly. For instance, if there is "file.Z", use "GET file" to get it uncompressed for you. 2) Load these files to your Commodore 64 or 128. Place a disk with enough disk space in the drive, and run the program. 3) You can extract LHArc files using Commodore CS-DOS's LHX or CP/M PMARC on the C128, or LHX64 on the C64. If you use LHARC or LhA on other platforms, you may find the LZHconvert or cbmconvert package in the pub/cbm/archiving directory useful. Note that there are many .lha archives that are packed using the newer -lh5- compression method, which is not supported by the CS-DOS LHX or LHX64. These must be undone using other tools. CS-DOS and CS-DOS LHX are in /pub/cbm/c128/cs-dos. PMARC is in /pub/cbm/c128/archivers/pmautoae.com. LHX64 is in /pub/cbm/c64/archivers/lhx64-0.9.sfx. LhA for UNIX in /pub/unix/tools/lha-lharc/lha-1.00.tar.gz LhA for Amiga in /pub/amiga/utilities/archivers/LhA_e138.run LhA for MS-DOS in /pub/msdos/packing/archiver/lhexe15.zip 4) You need Commodore 64, highly 1541 compatible disk drive and ZipCode program to extract these ones. The destination disk will have a custom file structure. ZipCode is in the files /pub/cbm/c64/archivers/*zipcode*. Alternatively, you can use the zip2disk module of the cbmconvert package (/pub/cbm/archiving/cbmconvert-*.tar.gz) to extract ZipCoded files to 1541 disk images. They can be used in some Commodore 64 emulators. 5) To lower the file count, ZipCoded files are sometimes packed with Unix tape archiver (tar). In order to reduce the file size, many of these files have been compressed with GNU zip (gzip). If you do not have GNU zip, the FTP.FUNET.FI can extract these files for you. For instance, if there is a file called "demo.tar.gz" in the default directory, getting "demo.tar" will send an uncompressed version of the file to you. You still need Unix tape archiver to extract the ZipCode files from these archives. GNU TAR is available for virtually all OSes, but not for 8-bit Commodores. If this is a problem for you, mail cbm-adm@ftp.funet.fi, and we will see what we can do. 6) 1541 disk images (filenames ending in .d64) have became quite common in 1993-1994. They are raw sector dumps of 1541 disks of 683 sectors * 256 bytes = 174848 bytes. Many data transfer utilities in /pub/cbm/transfer support the .d64 format and will write such files directly on 1541 disks. Also, there are some C64 utilities that can copy from .d64 to a disk image, but you'll need two drives for this approach, and the other drive must have more capacity to hold the whole file (689 blocks if using the standard Commodore format). If you can't use a cable-based transfer utility to transfer the disk images, then you're probably best off using a .d64 -> ZipCode converter, such as disk2zip in the cbmconvert package (for Unix, /pub/cbm/archiving/cbmconvert-1.1.tar.gz). Then you can use ZipCode (note 4) on the C64 to create the disk images. ZipCode works also with only one drive. Sometimes the .d64 images are compressed with GNU zip to reduce disk usage and transfer times. Also, some .zip or .lha archives may also contain .d64 files. Disk images compressed with GNU zip or PKZip can be decompressed into a 1541 disk with gunzip.c64 with even just one drive. See the gunzip homepage at http://www.cs.tut.fi/~albert/Dev/gunzip/ 7) Use convert2.5 to convert .cvs files to normal GEOS format.
