	 platform. It will be evolving rapidly, but the first version
	 offers the following features.  Many more features planned for
	 upcoming releases.

	 Connection manager makes it easy to keep settings specific to
	 different Xboxes or dashboards.

	 FTP browser (more FTP features will be added later)

	 ISO features:
	   Create double-optimized ISO files
	     Direct from FTP
	     From PC folder
	     Convert existing ISO to new optimized format
	     Optional automatic cross-linking of files
	   Extract files to PC drive
	   Direct-to-FTP upload to Xbox
	   True Average for transfer speed

Q02: Do I have to use Avalaunch if I want to use Qwix?

A02: No.  There are some features of Qwix that only work with Avalaunch,
	 specifically the Manage Titles screen, but other than that, most
	 features work with any dashboard.  There are other optimizations
	 throughout Qwix that will perform tasks faster with Avalaunch, but
	 the features will autodetect and work with other dashboards.

	 Transferring an ISO to the Xbox with Avalaunch can offer a huge
	 performance advantage.  You do not need to run Avalaunch as your
	 default dashboard.  You can run Avalaunch just like any other app,
	 then go back to your default dashboard when you're done with Qwix.

--

Q03: What is Boost Mode?

A03: Boost Mode is an improved FTP protocol that is currently only
	 supported with Avalaunch.  It can make transfers push the limits
	 of your 100Mb connection, and is especially helpful with transfers
	 that contain a lot of small files.

--

Q04: How do I enable Boost Mode?

A04: If you're using Avalaunch, the feature is automatically enabled.
	 Other dashboards don't support Boost Mode, but Qwix will use
	 normal FTP to transfer the files to them.

--

Q05: Is Boost Mode supported on my dashboard?

A05: Currently, if you're not using Avalaunch 0.47.5 or higher, the
	 answer is no.  Avalaunch is free and can be run as an app, so
	 don't worry too much if your dashboard doesn't support it.

--

Q06: What is a "double-optimized" ISO?

A06: A double-optimized ISO uses AVL trees for the directory
	 structure, and also positions the files in an optimal
	 pattern for direct-to-FTP extraction from RAR files.

--

Q07: When I convert an ISO to an optimized ISO, why is it bigger?

A07: Not all ISOs were created correctly in the first place.  Qwix cleans
	 up the structure, which may increase the size of the ISO, but in
	 many cases will actually reduce the size of the ISO, or stay the same.

	 It's also possible that you did not have automatic cross-linking
	 enabled when you converted the ISO.

--

Q08: What does "Automatically cross-link identical files" do?

A08: It is also sometimes called re-linking.
	 This may help save space in an ISO by making multiple file
	 entries point to the same data in the ISO.  This is a common
	 trick to make a title fit better on a CD.

--

Q09: Why would I want to convert an ISO with Qwix?

A09: There are a lot of ISOs that were created with ISO programs
	 that didn't make proper ISOs, and didn't take advantage of
	 available optimizations.  Problems in ISOs can include invalid
	 structure placement, too much padding after directory entries,
	 incorrectly calculated directory table offsets, and invalid
	 directory table sizes.  The problems can cause many ISO extract
	 programs to incorrectly extract the files, often manifesting as
	 missing files, and can also prevent the ISO from booting or
	 receiving "dirty disc" errors when burned to disc.  Often, the
	 ISO appears to be "mostly" correct, but in fact is missing one
	 or more files when extracted.

	 Qwix has smart ISO loading routines that can workaround these
	 problems and load the ISO, allowing extraction or FTP transfers.
	 Converting an ISO with Qwix cleans up all of these problems and
	 makes a clean ISO that can be used with any ISO program capable
	 of reading proper ISOs (meaning it supports the use of AVL trees
	 in the directory tables).

--

Q10: Can I create multi-game discs in Qwix?

A10: There's nothing to help you create a multi-game disc in Qwix 1.0,
	 but in a coming version, some automated wizards will assist you.
	 You can create them with v1.0 as long as you set up the directories
	 and menu files on your PC and then create the ISO.  Avalaunch 0.47.5
	 has some fixes that also help make it an easy alternative for
	 multi-game discs.

--

Q11: Can I create an ISO from FTP?

A11: Yes.  You can create an ISO from any dashboard with FTP.  You can
	 even create one directly from a DVD inserted in the Xbox drive.
	 See Question 12 for more info.

	 Note: Qwix doesn't support Boost Mode for the download in v1.0,
	       but v1.1 will support Boost Mode for ISO creation.

	 Note: Automatic cross-linking is not supported on dashboards other
	       than Avalaunch in v1.0, but will be supported in v1.1.  You can
	       either run Avalaunch, or transfer the files to your PC before
	       you create the ISO to allow automatic cross-linking to function.

--

Q12: Can I create an ISO directly from the DVD?

A12: You can if you insert the DVD into the Xbox drive, and select the
	 D:\ drive for FTP in Qwix.

	 Be aware that testing showed that not all FTP servers correctly
	 transfer files from the DVD.  You might need to copy the files to
	 the Xbox drive with xToolBox, xb-ftp, dvd2xbox or PxHDDLoader, and
	 then create the ISO.

	 You can NOT create an ISO by inserting an Xbox DVD in your PC drive.

--

Q13: What is Slack space in the Title Manager?

A13: The Xbox file system uses clusters of 16KB or 32KB.  Every file uses
	 at least one cluster.  Slack space is the amount of space that is
	 unused in the last cluster of a file.  So a 1KB file still takes
	 a 16KB cluster, leaving 15KB of slack.

--

Q14: Why doesn't Qwix show/check freespace?

A14: Every dashboard handles freespace differently.  There wasn't enough
	 time to make the feature work in v1.0, but it will be added to a
	 future release.

--

Q15: Why doesn't Qwix support language translation?

A15: Language translation takes a while to implement.  There wasn't enough
	 time to fully support it in v1.0, but it will be added to a future
	 release.

--

Q16: Why is the screen choppy when creating an ISO?

A16: ISO creation is not currently threaded.  Qwix 1.1 will create the
	 files in a thread, so screen updates will be as smooth as they are
	 for uploads and extractions.

--

Q17: Why are Qwix averages so slow compared to my other FTP client?

A17: Qwix uses a True Average for the transfer speed, meaning it considers
	 the total bytes transferred over the total time.  Most FTP clients only
	 consider the speed while data is being transmitted, and ignore the
	 overhead between files.  When transferring a lot of small files, the
	 extra time spent between files can be substantial.

	 If you want to compare speeds fairly, do the calculation manually
	 comparing total bytes transferred with your other FTP client, divided
	 by the total number of seconds spent during the transfer (from start to
	 finish).  You can not consider a portion of the transfer to be
	 representative of the entire transfer, because some titles have 80%
	 of the files in the final 20% of the ISO.

--

Q18: Why is the Max Speed ridiculously high?

A18: There is some debate regarding the theoretical maximum speed of
	 100Mb Ethernet, but the range is somewhere in the 11.2 to 12.8 MB/s
	 range.  Qwix hands data off to a buffer that is to be sent to the
	 FTP server.  Sometimes this buffer fills at a very fast rate and
	 returns control to Qwix, into ranges like 52 MB/s.  The Average
	 speed is accurate, and reflects the overall data transferred, but
	 you may want to ignore the Max Speed unless you're getting very
	 low values.

	 Changing Qwix to compensate for the buffer is not something that
	 is planned for any versions of Qwix.  Just take it with a grain
	 of salt.

--

Q19: Why doesn't Avalaunch Boost file count match Qwix?

A19: Avalaunch counts files and folders in the Boost Mode status window,
	 and Qwix counts only files.  They'll both hit 0 at the same time.

--

Q20: Why can't I abort a Boost transfer without crashing?

A20: Avalaunch cannot currently abort a Boost transfer, and Qwix is not
	 currently smart enough to recover from that.  Just don't do it; it
	 won't work no matter how many times you try.

--

Q21: Why isn't Boost as fast on my Xbox as it is on others?

A21: There are many factors that affect Boost transfer speeds.  The following
	 list covers the things we've found that can contribute to speed
	 problems.  This is not a complete list, and just because you have some
	 of these conditions present does not mean you will have bad performance.

	 1) Software firewall installed on your PC
	 2) RealTek or other inexpensive network card
	 3) Connected to an ethernet hub instead of a switch
	 4) Bad cable, or cable is too long
	 5) Quality of Service (QoS) is enabled in WinXP
	 6) 256MB of memory on your PC, or an older CPU
	 7) Gigabit ethernet NIC (try 100Mb mode instead)
	 8) Running background programs on your PC or network

	 Boost mode pushes 100Mb ethernet fairly close to its limits.  Anything
	 you do on your network to impede traffic is something that can easily
	 knock 1MB to 3MB per second off of your transfer speeds.  Many users
	 are getting a true average of 8MB/s to 10MB/s, sustained over an 8GB
	 to 80GB transfer.  If you're only seeing 3MB to 5MB/s, you might want
	 to examine your setup to see if any of the above conditions apply to
	 you.  If you find something that has affected your speed, please let
	 us know in the #qwix channel or the Xbox-Scene forum so that we can
	 add it to this list.

--

Q22: Where did the "Use advanced Avalaunch features" option go?

A22: This option told Qwix to issue a SITE REFRESH command to Avalaunch
	 after an entire batch transfer was finished or after a game was
	 deleted from the Title Manager.  Unfortunately, that command can
	 cause Avalaunch to freeze, but not every time and never while a
	 debugger is running.  That's what drives developers nuts.

	 After a fair amount of time trying to reproduce the problem in
	 Avalaunch on a development machine, we decided it was better to
	 pull the feature from Qwix 1.01.  It does not disable Boost mode,
	 or any of the other Avalaunch features.  It just means the menu
	 will not be refreshed to reflect the current set of titles on your
	 hard drive.  After we can reproduce the problem and fix it, the
	 option will be returned to Qwix in a future update.
