The LTZ utility is on the registered version. Linux LTZ Utility LTZ [-ascii] filename Will uncompress a single file from Linux. The -ascii flag will convert the irregular LoseThos ASCII 5 and ASCII 31 characters to spaces. (ASCII 5 is used to mark the cursor position and ASCII 31 is used for shifted space characters and will cause problems unless you convert them.) Windows LTZ Utility LTZ is a Windows cmd line program which will assist transferring files from LoseThos to Windows. It will also uncompress LoseThos files you have gotten to Windows. There are three ways to get files from LoseThos to Windows -- via CD-ROM, a FAT32 partition or via a "file partition" you have created with LTZ on a Windows partition. LTZ -expand [-ascii] dirname: will uncompress all LoseThos files with names ending in 'Z' in a Windows directory and in all subdirectories. The -ascii flag used in combination will convert the irregular LoseThos ASCII 5 and ASCII 31 characters to spaces. (ASCII 5 is used to mark the cursor position and ASCII 31 is used for shifted space characters and will cause problems unless you convert them.) Note: If you pick names not ending in 'Z', they will not need to be uncompressed. You can Move() or Copy() them to a name not ending in 'Z' and they will be stored uncompressed. LTZ -make megcnt partfilename signnum: will create a file on a Windows partition and fill it with a signature num that can be searched for block-by-block from LoseThos. Once some blocks have been allocated by Windows and located by LoseThos, and if you don't mess with them, you can use them to transfer files between LoseThos and Windows. This is a little risky. It's pretty safe if you create this file on a partition dedicated for this purpose. NonLTScan(): is a LoseThos cmd which will scan for some blocks created by LTZ and provide a block num you can use to specify a "Non-LT file partition". You can recompile OSMain and define this partition or use Mount() each time. You will be asked to provide a drive letter and from then on, you just copy files to that partition, boot Windows and run LTZ to extract them. LTZ -extract dstdirname partfilename: will copy all files in a file partition to a Windows directory, making them available from Windows. WARNING: Do not attempt to uncompress files twice or it may crash. If there are any files ending in 'Z' which are present, it'll may crash too. You might get really unlucky and it uncompresses and creates havoc. WARNING: Do not run a defrag operation on a partition holding a file partition. If you store files to it after such an operation, you'll ruin data on your hard drive. * "Windows" is a trademark of MicroSoft Corp. * "Linux" is probably a trademark owned by Linus Torvalds.
