-
- 6. About "Options" menu
- A. "BackGround On"
- In the "Options" menu, "BackGround On" is available only under
- MultiFinder. When LHA starts under MultiFinder, first this option
- is off.
- If this option is selected, while both freezing and defreezing,
- you may bring other application as a foreground job, and let LHA
- work as a background job. But the execution speed becomes slightly
- slower.
- When this option is off, LHA cannot run as a background job of
- other application. But in this case, the performance becomes
- faster.
-
- B. "Show Type"
- In the "Options" menu, "Show Type" decides the file type stored
- in archive file.
- If this option is selected, one check button and nine radio buttons
- appear at the bottom of a list of archived files. They are divided
- into "MacBinary", "Path", "Header", and "Type". When a list of
- archived files appears, "MacBinary" is ON, "Path" is partial,
- "Header" is level 1, and "Type" is LHA.
-
- B-1. "MacBinary"
- Each "MacBinary" file has a 128 byte header at the beginning of it,
- and both Data Fork and Resource Fork are stored into archives. Since
- there is a header block added at the begging of each file, you have
- to care to exchange the file with DOS LHA and others.
- "Normal type" does not have any header like "MacBinary", but
- it stores only either Data Fork or Resource Fork into archives.
- If a file has only either Data Fork or Resource Fork, it's stored
- into archives. In case a file has both Data Fork and Resource Fork,
- only the Data Fork is stored.
-
- B-2. "Path"
- You can select the format of file name in archive files by "Path"
- radio button. You can select 3 kind of path, "non path",
- "partial path", "full path".
- Let's assume a file exists as "/THINK C/Mac Libraries/MacTraps" in
- your archive file, for example. You can get the file name "MacTraps"
- from your archive, if "non path" is selected. In case "partial path"
- or "full path" is selected, you can get
- "THINK C/Mac Libraries/MacTraps ".
- In the freezing phase, "MacTraps" is stored in your archive, when
- "non path" is specified. By "partial path" option, if you select
- the file directly, "MacTraps" is stored. If you select a folder
- "THINK C", "THINK C/Mac Libraries/MacTraps" is stored in your
- archive file. In case "full path" is specified, the file is stored
- as full path name like "/THINK C/Mac Libraries/MacTraps".
-
- B-3. "Header"
- "Header" decides the format of file informations stored in archives.
- You can choose "level 0", "level 1" or "level 2" of "Header" radio
- button. When the "Type" menu is set to "LHarc", "level 0" is
- specified by force.
-
- B-4. "Type"
- "Type" decides the format of file informations stored in archives.
- In the "Type" radio button , you can select one of three types,
- "LHarc", "LHA", or "none". "LHarc" selects -lh1- as its compress
- method. "LHA" selects -lh4-, -lh5-. No compression is done by
- "none".
- When LHA defreezes, "type" specification does not limit compression
- method of defreezing files.
-
- C. "Folder Info. visible"
- In the format of file informations stored in archives, there is
- special format (-lhd-) which indicates about folder. If this option
- is off, the format does not appear in a list of archived files.
- When LHA starts, the format does not appear in it.
-
- D. "No beep when finished"
- If this option is on, the beep does not let you finish freezing or
- defreezing.
- When LHA starts, the beep lets you do so.
-
- 2. Compatibility
- MacLHA has the compatibilities with LHA, LHarc or LArc for each
- system.
- But if an archive file created by LHarc for other systems has sub
- directories in it, sometimes MacLHA cannot defreeze it correctly.
-
- 3. Changes from former versions
- Please read another text file (in Japanese).
- This version is modified only about error on 68000 CPU Macintosh
- (Ex. PB100) when freezing and defreezing are finished.
-
- 4. Warnings any restrictions
- Until LHarc 0.32, defreezing a file which has either Data Fork or
- Resource Fork occupies more than 100 KB and which has both Data
- Fork, the defreezes file was not correct one. In such cases, the
- archive file itself is correctly stored, so please defreeze with
- LHarc 0.33 or later, or LHA.
- Frozen archive file by LHarc 0.40 (a or b) is not correctly stored,
- so please refreeze by other version of LHarc or LHA.
- This program works on HFS system only.
