I'll rewrite these programs in English and with my new libraries and make them open source as a demo in the OS 9.3 SDK. Then you can adapt them to your own taste.

deleting the icons doesnt make a difference because a file marked as "deleted" is still where it was before. and even if the space will be overwritten later, these new files will still be fragmented likewise.

i agree with those who say that it normally doesnt make a big difference. but i was using custom icons in the search path of a programming language and i had to stop it one day because is was slowing down things - if you have 800 folder with 800 files inside, you double the amount of items if you apply icons.

as for application folders already coming with icons... i always delete those because it looks ugly. Smile

In OS 9.2.3 everything was ordered like a website; the documentation is separated from the software. In OS 9.3 everything is ordered like a shareware CD; every piece of software has its own folder with its documentation.

Those who saw the OS 9.3 preview know that all my extensions which use CatSearch to do some stuff (like "Delete icon-MACS files") are discontinued. In rare cases you have a chance that you get a crash if several of those extensions do a CatSearch at precisely the same moment. I saw it happen only once but that's the reason why I removed them.

I thought it was a recommendation to not use custom folder icons. I'm shocked to see this autoerase things on me and I wasn't warned. Anyway, thank you to OS923 guy, we love this kind of stuff. But irony on hi is that by erasing preexisting folder icons it must be CAUSING fragmentation a lot.

@SkyCapt Here's what DieHard from MacOS9Lives had to say about the icon x fragmentation statement:

Well, maybe that is true on a pre-G3 machine, but this statement is a little extreme for my taste on an MDD. I use a program called "icontools" where I can right click and "stamp" icons on my folders and make custom icons, and I would say I love this feature in OS 9. It has never impacted performance on my DAW (at least that I could tell) and I have seen the hell a heavily fragmented disk can do to a Studio mac... so I am not in agreement here... I have hundreds of custom icons, I like them Smile

I, too, haven't ever noticed such issues, even on pre-G3 Macs. If it has any impact, it seems to be negligibly small, even on an HDD.

I played with d7. G4-Extensions work independently, Caps Lock Beep that's self explanatory, No Battery I didn't see docs for so we need to click on it in Extensions Manager to read its description, No Battery is a clock utility which allows the clock to remain mostly right in conjunction with "no battery" whenever you shutdown and repower quickly (restart).

But this extension named "Delete icon-MACS files" everybody think twice before installing this piece! Our author was once quoted saying custom folder icons are like having a badly fragmented harddrive, so here's an extension which erases the icon of every folder you touch, and I'm using an SSD not HDD so fragmentation doesn't exist for me to begin with.

I wouldn't use these programs on a computer with OSX installed. This has not been tested.

The disk images shouldn't be a problem with Disk Copy 6.3.3. I tried them before upload. The documentation is a copy of what used to be on the website and contains a link to the download that contains the documentation. Circular indeed. On the website I used a Gzip download. Now it's StuffIt 7.

I extracted and mounted the v105d file OK - but I was using Tiger 10.4.x and Disk Utility to do it.

- The Help.html has a download link to "file:///Volumes/OS 9.2.3 v1.0d5/Help/os923v10d5.gz" which I assume is the OS 9.2.3 binary to install 9.2.3 over an original 9.2.2? - anyway, "os923v10d5.gz" is missing from the Help folder.

Tho' I think these will be the extracted folders also in the mounted image and (I'm guessing) you would need to manually install.

I haven't look at the other DL's as yet.

I have tried opening both version v10d5 and v10d7. On v10d5, DiskCopy yields the following result: "The Mount Image operation did not complete. (-8816) The file 'os923v10d5.img' does not have a recognized file type." When I try v10d7, I get the same message. I'm running MacOS 9.2.2 on a PBG3 Pismo, 500MHz, 640MB RAM, 20GB HDD. Suggestions?
