- 5.A ARCHIVE CONVERSION (WITH VIRUS CHECKING).
- =============================================
-
- Conversion of archives to UC archives can be done fully automatic.
- Perfect for the event list of your BBS. Conversion includes the
- optional calling of one or more virus checking programs. Any virus
- checking software can be used. You can define any extraction, checking
- or processing software you would like, to be called by UC.
-
- IF EXTRACTION IS NOT PERFECT UC WILL NOT CONVERT!
-
- The convert command
- -------------------
- Command: UC C archives
-
- C is the convert command. ARJ/ZIP/LZH etc. archives are converted
- to UC2 archives.
-
- Example: UC C *.ARJ *.ZIP *.ARC
-
- All ARJ, ZIP and ARC archives in the current directory are
- converted to UC2 archives.
-
- VOLUME LABELS, BANNERS, MULTIPLE VERSIONS OF A FILE AND COMMENTS
- ARE NOT CONVERTED.
-
- The original archive will be deleted by UC.
-
- Customizing archive conversion
- ------------------------------
- To convert archives to UC archives the original archiver's software
- will be used. In the UC package some .BAT files are supplied which
- are able to extract all files from different archive types (see
- chapter 6 paragraph D).
-
- UC uses advanced swapping techniques to swap UC out of memory while
- execution of the BAT files takes place. This assures the archivers
- have enough memory available.
-
- Currently supported formats are: ARC, ARJ, HA, HPK, HYP, LZH, PAK,
- ZIP and ZOO.
-
- UC conversion also supports the 'UCN' format. This format is
- exactly the same as UC2, but it denotes 'N'ew files. It can be
- used to mark files new to your BBS, allowing 'conversion' to UC2
- archives. This is usefull since conversion can also include virus
- scanning etc..
-
- Virus checking during conversion
- --------------------------------
- When you activate virus checking (see chapter 6 paragraph A item E)
- during conversion, the file U2_CHECK.BAT is used. In this batch
- file virus scanners are called. If you want another virus scanner
- to be used, or use more scanners in the check, you are free to
- change the file U2_CHECK.BAT. Just be sure the virus scanner called
- is available on your system. Default U2_CHECK calls McAffee and
- F-Prot.
- (See chapter 6 paragraph D.)
-
- Automatic changes during conversion
- -----------------------------------
- The supplied U2_XTRA.BAT file can be used to make automatic changes
- to archives contents during their conversion. Such a change could
- include the addition of multimedia banners. The U2_XTRA.BAT file as
- being distributed with UC does nothing at all, but can be adapted
- to do anything you like. The U2_XTRA.BAT file contains (disabled)
- sample code for adding banners to archives during their conversion.
- (See chapter 6 paragraph D.)
-
-
- 5.B MULTIMEDIA BANNERS.
- =======================
-
- UC gives you the opportunity to add (multimedia) banners to archives.
- Five file types are supported:
-
- U$~BAN.GIF GIF image
- U$~BAN.JPG JPEG image
- U$~BAN.MOD MOD music files (playable with e.g. Modplay)
- U$~BAN.TXT Standard text (will be integrated in UC output)
- U$~BAN.ASK Special file (determines if UC2 asks 'Continue?'
- after showing/playing the banners. The content of
- this file is of no importance.)
-
- If you want to add a banner to an archive, you will have to specify
- the banner file explicitly. No wild cards can be used, e.g. 'UC A arch
- U$~BAN.*' will not work.
-
- Example: UC A arch U$~BAN.TXT
-
- A text banner is added to the archive arch.
-
- The file U2_SHOW.BAT contains the default software to show or play
- banners. See chapter 6 paragraph D for more information on this batch
- file.
-
- The banners are shown/played when files are extracted from the
- archive.
-
-
- 5.C ULTRASTEALTH (RUN UC WITH ONLY 32K FREE MEMORY).
- ====================================================
-
- With help of UltraStealth, you can run UC with only 32 kilobytes of
- free memory available.
-
- Suppose you have a huge program (e.g. a word processor or a mailer).
- When this huge program has the ability of starting another DOS program
- only a small amount of memory will be free. UltraStealth allows you to
- have this huge program call UC. To achieve this you need to do two
- things:
-
- (1) the (huge) program has to be started with US (UltraStealth)
- ---------------------------------------------------------------
- Just put US in front of the normal command you use to start the
- (huge) program. So if the normal command is:
-
- bigprog /a /q
-
- You now have to use:
-
- US bigprog /a /q
-
- (2) use UUC instead of UC
- -------------------------
- Instead of calling UC from your (huge) program, you should call
- UUC. UUC behaves exactly like UC. The only difference is that US
- and UUC together solve the memory problem the (huge) program
- causes.
-
- It is also possible to start US with no command behind it. In this
- case the DOS command processor (command.com) is started and UUC can be
- used anytime. The command processor (and US) can be stopped with the
- EXIT command.
-
- When UUC is called, while US is not active, UUC starts UC anyway. In
- this case there is no difference in the amount of memory needed for
- UUC and for UC.
-
- US and UUC together use about 32k of free memory, most of this will be
- claimed by US.
-
- Please note currently US and UUC only work with the native command
- processor, command.com, not with tools like 4DOS.
-
- Due to the complex nature of UltraStealth, it is recomended you
- test-drive UltraStealth thoroughly in your specific environment before
- you start using it.
-
-
- 5.Z SUMMARY.
- ============
-
- UC C *.ARJ *.ZIP *.LZH
- Convert archives to UC archives.
-
- US <command>
- Executes <command> and installs UltraStealth (needed to use UUC)
-
- UUC ...
- Exactly the same as UC, but much less memory is needed. Will only
- work with a small amount of memory if UltraStealth is active.
