Registry & Defrag utilities

[Skii]

Where can I get registry cleaner and defrag tools?

[Beverly Howard [Ms-MVP/MobileDev]]

afaik, there are no "registry cleaners" for the ppc. you can always
start clean with a hard reset

it is not necessary to "defrag" solid state memory

Although he could potentially have a microdrive, which being a normal
hard drive would possibly benefit from defragging. No idea of PPC
defragging tools though, never looked into it myself. I'd use a card
reader and defragg it on the desktop personally.

I don't know of any registry cleaners for the ppc. I'd do a
hard reset AFTER A FULL BACKUP then do a clean install of
the software you intend to keep.

SKTools has some registry cleaning tools..

There're several registry cleaner utilities; for example, SKTools, MemMaid.
Of the two, I'd go with the former. Make a generic search for "SKTools" in
my blog for more info.

Also, there're several ways of defragmenting Flash ROM-based meomory, let it
be a memory card or a built-in File Store. Please see the article at
http://www.pocketpcmag.com/blogs/index.php?blog=3&p=521&more=1&c=1&tb=1&pb=1
for more info.

Even flash ROM's benefit a LOT from defragging.

I know it's hard to believe at first - neither did I believe this before
I've done some really extensive, quantitive benchmarks.

Interesting, any chance you could post a link, or is it something you
haven't published? I searched your blog, and found a link to a thread
that's supposed to contain quantitative results on this, but while it
does link to an exhaustive set of tests comparing different format
parameters on several brands of card, I can't see any tests comparing
before/after defragging, unless I'm being blind.

http://pocketpcmag.com/forum/topic.asp?TOPIC_ID=17921 is the thread.

Well, I already saw that one, in fact that one links to the article
that links to the forum thread that I mentioned above. And as with
that, there is a comparison of effects of different format parameters,
but there is no formal comparison that I can see of fragmented vs
defragmented performance.

Anyway not other than one sentence mentioning offhand a 30x speed
increase in the LOOXstore write speed of your Loox 720, but no details
or methodology - personally I think there has to be something else
going on than fragmentation to see a 30x difference.

Maybe I will knock something up to intentionally fragment a storage
card, so I can do some repeatable tests, now that you've got me
curious.

If you have a storage card you haven't formatted for a while but always copy
files to/delete files from, try copying a large file to it (and reading
back). Then, do the same after formatting. There will be sometimes huge
differences.

Well, it was the "really extensive, quantitive benchmarks" you said
you had done to prove that that I was looking for, rather than an
empirical observation ;).

Never mind, like I say, I shall try and knock together a repeatable
test setup myself.

I've made a lot of tests, but still hadn't had the time to document them.
I'll do this really soon.

Anton Tomov has Pocket Mechanic Pro almost ready to release. There are
Registry cleaning tools there as well as a very fast defrag tool. (One
thing that has always been nice about his programs is that once you buy
it, you are entitled to free upgrades forever.)

Personally, I like keeping in touch with what is installed on my PDA
well enough that I can go into the Registry and clean out the left over
entries manually. Plus I also keep backups of the PDA at specific
points where I know things were stable and only what I wanted are
installed. If I screw up, I can always go back to one of those backups
and get things running again.

Good luck,
Chris

Please note that Pocket PC-based defrag / checkdisk tools are better to be
avoided. The same can be done on the desktop, much easier, much faster and
much more safely.

some horror stories.

I agree with you. I don't know the particular circumstances, but I am
reluctant to use any tools such as these for editing the registry or
working with a storage card till I (a) have a known good backup and (b)
have tried them enough to depend on them. However, sometimes you are
desparate and your choices are limited.

On the PC side, I've used Symantec's Norton Disk Doctor and found it
trashed my hard drive, and always felt CHKDSK would've worked better.

I think Anton's new product may be worth looking at. He's bypassing
"the file system drivers of Windows CE and access(ing) the files
directly through our own FATFS layer..." From what I've seen in beta
testing, it works.

Well, that is not defragging as much as it is just allowing the card extra
room to write a large file first. This will always be the case for smart
storage devices, which are trying to "spread out" writes across its media in
order to make that 10,000 write cycle last longer. Technically it is not
as much defragging as it is allowing the card to optimize itself, since by
default the card will not be writing to consecutive clusters of memory.

I think we may have had this discussion before, so forgive me if I am
beating a deceased equine. :)

[Tony A.]

As it goes, I've just now finished my own tests on this, because
frankly I thought Werner must have been exaggerating the effect (sorry
Werner, I'm just naturally sceptical), but my results seem conclusive,
I'm certainly now convinced that fragmentation does indeed have a
major impact on flash performance, at least with the card and PDA I
tested with. So, I guess Werner busts another myth ;).

I missed out on any earlier conversations on the topic, so no idea of
the mechanism behind the performance loss, since obviously it's not
down to seek time a la hard drives. Maybe something like the wear
levelling comes into it, but at the end of the day fixing the
fragmentation also fixes the performance, from the users POV, so I
guess the mechanism is academic.

[Werner "Menneisyys" Ruotsalainen [MVP - Windows - Mobile Devices]]

I've forgotten to add that only do this in the remaining disk space of a few
Megabytes so that it is reused. First, fill up the entire card with stuff
that, later, you don't touch.

Yup, I've busted a lot of other myths too - for example, the myth about
enabled IrDA ports resulting in much higher power consumption.
