- Compressed File Manipulation
- ----------------------------
- ^variantname has four capabilities related to compressed files. The
- first is explained more fully in the UPLOAD help file, so we'll just mention
- it here: ^nodetitle may be configured to optionally test compressed files
- after uploads (by invoking external programs).
-
- Second, you may peek into the Table of Contents of any compressed file
- (that is, any file with an extention of ARC, ZIP, ZOO, or LZH). The
- command for this is
-
- <.R>ead <A>rchive <D>irectory
-
- You will be prompted for the name or names of files to peek into, and
- you may use file-specs and date-specs when you answer this (as explained
- in the DOWNLOAD help file).
-
- Third, you may be able to ask ^variantname to compress messages before
- sending them to you using the <C>ompress option on .<R>ead. For instance,
-
- .<R>ead <X>modem <C>ompressed <N>ew <CR>
-
- would result in the new messages in the current room being sent to you using
- the compression method you specify (you're prompted after the carriage return),
- using Xmodem for the transfer. Naturally, other protocols may be specified.
- A single file will reside in the resulting compressed file.
-
- .<R>ead <G>lobal <X>modem <C>ompressed <N>ew <CR>
-
- would send a compressed file of all the new messages on the system to you.
-
- Fourth, you may be able, depending on how the sysop has configured the
- system, to extract one or more files from the compressed files for download.
- Normally, when faced with a compressed file you'd simply want to grab the
- whole thing. However, sometimes it's desirable to extract a file or two
- from a compressed file. Perhaps a READ.ME file is enticing, perhaps you
- just need to get an updated file. In any case, being able to extract one
- or more files from a compressed file can be useful. The command for this is
-
- <.R>ead <A>rchive <F>ile
-
- You will be asked which compressed file you will be decompressing from.
- You may only specify one file here, but you needn't mention the extension;
- if ^variantname can't find what you type, it'll append a .ARC, .ZIP, .ZOO,
- and .LZH (in that order) until it finds the file or runs out of extensions.
- If ^variantname finds the file and ^nodetitle is configured to support
- decompressing files of that type, it will then ask you for
- a "deARC mask". All this means is that you may now tell the decompress
- utility which files to decompress. You can answer with a list of files
- (separate each file name from the next with a space) or use normal "wildcard"
- characters or a mixture of both.
-
- ^variantname will now try to extract the files you asked for from the
- compressed file. Be patient, especially if the computer the BBS is on is
- slow. When the decompressor is finished, and if it found any files to
- send to you, ^variantname will start sending the files.
-
- But using what transfer protocol? Using the basic .RAF command from above,
- ^variantname would use ASCII for the transfer, which may not be appropriate
- if you were trying to get executable files. Therefore, you may modify the
- .RAF command with any of the protocols supported on ^nodetitle (see PROTOCOL,
- below). For instance, to transfer a bunch of files from a compressed file
- using YMODEM (BATCH mode), you'd use
-
- <.R>ead <Y>modem <A>rchive <F>ile
