Looking for a file splitter for OS8/9

I'm trying to find a program that will let me split a file into pieces of a set size. There is a tool like this here called SplitIt but it writes a file header onto the output files. I need a util that doesn't modify them in any way.

I found a shareware util called Fast File Saw & Joiner but it won't let you specify an output size larger than half the total file size.

Tried and failed so far:

SplitsVille: Has a checkbox to append a joiner header. Can't uncheck it.
MacNetTools: 8MB max chunk size.
DropSegment (from Stuffit): Filesize in kB (needs to be in B).

MacRAR perhaps? Don't know if it'll do what you want as I haven't used it for this, only know it can split archives. HTH.

[Edit] Hmm... Thought I'd try it out... Its splitting of files is very rudimentary and bug ridden. On 68k anyway, crashes actual 68k hardware and Basilisk II. I definitely don't recommend this one.

StuffitDeluxe can do that job very good.
I think version 5.5 or 6 (The 6-7 are very well carbonized).
The thing is that you have to stuff it first, then split it in any size you want.
You can set the split size from the menu Preferences.
Stuffit do recognizes all parts of the splitted file, you can even choose to delete them after expand.
It goes from sizes of 600k (old diskettes) to dvd-roms size 4.4gb (from the version 6or +, i think).

@Protocol 7: Compact Pro 1.5.2 - I find this to be very reliable for spitting files (Mac OS 7 - 9). You can specify an output size larger than half the total original file size. None of the resulting split chunks contain Mac Resource forks (so they are all portable). When rejoined, the resulting file has the same MD5 checksum as the original file before archiving/splitting... so if there is any header writing to the output (I haven't checked) then it must be removed in reconstruction.

There is a Compact Pro app archived here at the Garden, but it doesn't disclose the version number of this CP on the page. I use vers. 1.5.2 which I think was the last vers before it become abandoned.

To be aware of:

You need to save whatever you want to split, to a Compact Pro archive first, before splitting.

Compact Pro has only a limited range of file sizes to split to, but you can choose a custom file size of any amount (up to 2 GB) in Kb's, not bytes.

If you have the "Stuffit Engine" installed in your System's Extensions folder, Stuffit Expander can extract the contents from .cpt archives OK. Before the introduction of the "Stuffit Engine", earlier versions of Stuffit Lite and Deluxe had translators that could extract .cpt and other archive formats OK, too.

Thanks for the suggestions guys. I'll try Compact Pro next. I'm trying to find a tool to simplify my guide here. Using HexEdit is quite messy (considering in OS X that whole section can be done in a single command line). So I need a tool that will cut the file to a set size without adding anything to it.

OK, no luck with Compact Pro. It will only segment it's own archives.

@Proticol 7:
Have added "Split & Join" to the list of available file splitters for Mac OS 8/9 - Unfortunately it won't be what you are wanting, I think, as it does add headers to the split files and you can only determine splits in K's. Although in re-joining the split files it does remove those added headers & the joined files match their original's MD5 checksums, plus the split parts contain no Resource fork (good for mailing/uploading).

Its a really excellent tool otherwise and super fast at what it does plus you can split any file with this, so someone may like it. - I'm getting the feeling tho' (because of these Data & Resource fork issues) getting a file to simply split a "Classic Mac" apps file is not so simple as say a nice UN*X app like "split" then using "cat" to put it back together again.

A long time in coming but I think I may have found one. Its called "File Chop".

In amongst this bunch of info-mac utes, locate the file "file-chop-10.hqx" . . . Dec 19 2000, 594K and DL.
It appears to split large archives, .sit, .iso, .cdr, etc; and not write to the split chunks. PPC only.

Fingers crossed now Wink
