Why hasn't anyone developed an app that can open obsolete files?

[machenryr]

The problem with old OSes and computers. I go back with Mac to the 80s. I still have most of my old drives. I have one or two computers still from back then. I have no idea whether they will still boot. 10 years ago my IIsi still booted. But it seems there would be a market for someone to develop an application or a means of opening old OS files. Or to partition old OSes. Not possible? Does something like this exist? I'd love to open old Word, Appleworks documents, my old Eudora mail program. All lost histories. In the mean time, when I have time, I'll dig out that IIsi and see if it will still boot and figure out a way of salvaging some history.

Uh.. there are numerous emulators which can run ancient versions of Mac OS.

Getting at your ancient software data files might be the bigger challenge depending on where they exist.

LibreOffice will open old AppleWorks/Clarisworks files. I used both of those heavily at home and work until around 2000 or so when I switched to MS Office. I can still access my old files though with LibreOffice. Funny, two days ago a friend had the same complaint, about how he had all these old AppleWorks files he couldn't access. Told him about LibreOffice and he was amazed (and delighted)!

I believe it will also open your old Word files.

You can probably find a method to deal with most old file types…but I'm thinking of the piles of money that will roll in if I develop a universal app!

Well in a sense we already have that in that you can open any "file" in a text editor or hex editor to observe the internal structure of the file. I guess what you mean is a "universal" app that can read and logically display the information in any file type. By definition that's very difficult to do because every file type is different and the internal structure makes sense only to applications that know how to understand it, whether that be proprietary binary, XML with a specific schema or whatever.

You could build an app that understands a large number of file types either by reverse-engineering proprietary files and/or incorporating open standard file types (such as .odt) but that's not really universal, simply an app that knows how to open a large number of different file formats, and would also have to be reguarly maintained to add support for new file types. And even then your application would have the problem of how to display the data from these files, presenting a Word (type) document is different from (say) a photo so there'd have to be a mapping between the file type, the internal logic of how to process the file type and the internal logic of how to present the data. Seems like a big job to have to do that for every file type in existence!

Like Boyd mentioned above:

Issues that could crop up with old disks/files:
IF the data exists on old floppy disks, and IF the floppy disk is the original Mac 800k or 1.4 disk that requires a Mac-only floppy drive, then you're going to have a problem reading it. The Mac-only drives use a different disk formatting/encoding system than did "DOS" 720k or 1.4?) floppy drives. You'll need an older Mac with an original drive in running condition.

ALSO...
Somewhere along the line (can't remember just when) Apple dropped support for the old HFS format (as distinguished from HFS+). So, on the Mac side you'll need an older Mac running an older version of the OS to access an HFS drive (floppy or otherwise).

Having said this:
Files are "lost with the passage of time" because the user didn't take care to archive/preserve them in a format that would remain accessible over time.

I still have a database created in 1987 that I can access today.
I have emails and documents written in 1987 that I can open today (in fact, they're right here on my 2025 m4 Mini).

As the years have gone by, and the Macs have changed, along with the OS's AND the apps that will run on them, I've migrated important files (such as bank records, tax records, etc.) from one app (such as ClarisWorks) to something more modern, such as Numbers. I just checked and I was able to open a checking account record from 1988 (although in reality I'd very seldom do that, but the files "are there" if need requires).

For long-term archiving, it might help to save files in a universal, "non-machine specific" format. Thinking of ".xls" or "open document" for spreadsheets, rich text for word-processed docs, etc.

 

[NoBoMac]

What @bob_zz123 and @Fishrrman said.

Don't think there is a real market for something like this. "Real" being can make a profit on a program for this.

Companies/organizations that might have deep pockets generally won't bother as costs money re: software, man-hours.

Average Joe/Jane user, they want it free, no subscriptions, not going to pay more than $X. Oh and expect infinite software updates, new formats supported for their minimal/no investment.

Heck, even when they know the format, still can be a pain. Years ago, company I was at updated our PCs to latest version of Office, which "broke" pretty much every template we had, legacy documents (things were shifted, wrong place, fonts got munged, logos off, etc, etc). You'd figure MS would be able to read in their older formats easily, but...

 

[eRondeau]

There are online resources (websites) that claim to open/convert hundreds of different file extensions. Zamzar.com claims to open 1,200 different file types. I’ve used it successfully to translate even ancient Amiga files. As a sidenote, the sheer longevity of .pdf’s and .doc’s and .xls’s amazes me. I recently opened a 300-page .pdf saved on a CD-ROM in 1994 on my M4 Mac and it loaded & displayed perfectly. Truly impressive!

... I recently opened a 300-page .pdf saved on a CD-ROM in 1994 on my M4 Mac and it loaded & displayed perfectly. Truly impressive!

One reason for that is the history of PDF.

History of PDF - Wikipedia

en.wikipedia.org

Its initial features have been quite stable, and things were mainly added rather than replacing existing things.

 

[Boyd01]

I remember installing the original public beta of Mac OS X on one of our G4 towers, just to get acquainted. I thought one of the coolest things was Quartz, which was (as I understood) based on PDF. It was really amazing that you could "print" any document directly as a PDF. I continue to use that feature to this day.

Going back farther, I got an Apple ][ back in 1978 and actually still have a lot of those files, which (like @Fishrrman ) I have migrated from computer to computer over the years. It really is a lot better to do it that way instead of waiting 20 years and hoping you can find a way to access your old data. But "better late than never", of course.

 

[NoBoMac]

This.

If I deem it important (or semi), print it as a PDF and archive it to my array of external drives and cloud accounts.

I cut my teeth in the digital Stone Age where memory/storage was scant and expensive, so was never a digital pack rat: how many emails, for example, do I need to keep from years ago and most without any real info (eg. "I'm landing at 7:00pm on flight 123"). To this day I tend to flush almost all my emails, texts. One text thread is long but it has some value as sharing info on new beverages, cigars that are exchanged between me and brother in law (to make sure I'm not duplicating data exchanges).

Along those lines, I used to work for a company that dealt with storage products and back then they did a study that showed that after a couple of weeks, most data was basically "dead"/inert, so why waste space on your fast/prime/frontline storage for this "old" data. In the case of email, everyone is talking about issue A, in a couple of weeks issue A is done with and moved onto C, D, and E. This type of thing needed to be documented in project documentation that gets archived.

[Varmann]

As many said here, the challenge is not to open old file formats (but there are of course some exceptions), but to get access to the files themselves. The sensible longterm approach is to continuously move old (valuable) data over to newer formats. The longer it takes the greater the chance for snags to turn up.

There are so many storage formats that have been obsolete for so many years it would be a real challenge to get access to them nowadays. My old dataset from my PhD is still safe. It was original on a "huge" 10 MB Lotus 1-2-3 spreadsheet from 1987, but has been migrated up through different Lotus versions, dBase-files, Quattro Pro, Excel, Openoffice, Liberoffice, on 5 1/4" and 3 1/2" diskettes, zip drives, CD-disks. Some of my colleagues had their old data on 8" diskettes and punchcards (still used in the 80´s) and I would not dare to think about the challenge to get access to that today.

 

[Fishrrman]

Varmann -

I believe there are companies that specialize in migrating "old data" from old hardware to new formats and new hardware.

Of course, one will pay for the services.

For an individual, the only options are to keep older hardware around, OR (as mentioned above), try to "package" one's data with an eye towards the future (i.e., keeping WP files in pdf format or text/rich text format) ...

 

[machenryr]

Well closing the door after the horses got out is not the solution I was looking for. In 1985 when I got my first Mac+ I wasn't savvy enough to even THINK about backing up or saving in a format I could open in the future. That started occurring to me around 1995 I think. But I only had a PDF Reader at the time. I know better now. But now that the barn has already burned down I'm looking for methods of opening old files.

It seems to me it could be a very profitable program. There are some programs that are continually updated based on user requests. I already know a few music program I'll probably never be able to open without the Mac II or something. But I'd be willing to pay for it.

It does, I have Word files from the late 90s that open with LibreOffice.

How about being a little more specific on the files you have that you'd like to access, and what kind of storage they're located on?

The "solutions" will vary, according to "what you have"...

 

[machenryr]

Sure. The aforementioned Appleworks, but some are more obscure and impossible I'm sure. Hypercard not as obscure. Music programs like Mosaic, and Professional Composer, MOTU's Performer, Opcodes Galaxy, MidiMac and Vision. But also Eudora mail program. I have archived discussions on old BBSes.

 

[chown33]

What format are the Eudora archives stored in? If it's MBOX, then those should be importable directly into a Mac's Mail.app.

It's been ages since I left Eudora, but I'm pretty sure I just exported everything as MBOX and imported it into my Mail.app. That was probably on Mac OS X.1 or something, and it would have been on a G4 PowerPC. It was probably coming from OS 9.something.


Depending on what you intend to do with Hypercard, your best option may be trying to get an old PowerPC Mac running a suitable OS version. The Wikipedia article on Hypercard says:

HyperCard - Wikipedia

en.wikipedia.org

HyperCard runs natively only in the classic Mac OS, but it can still be used in Mac OS X's Classic mode on PowerPC based machines (G5 and earlier). The last functional native HyperCard authoring environment is Classic mode in Mac OS X 10.4 (Tiger) on PowerPC-based machines.

We have a PowerPC forum here, where you might find some more specific info:

Power Mac, PowerBook, iMac Gx, iBook, etc...

As told you @NoBoMac, no software from the same company will open an old file from the same software from the same company that is decades old.
Today's 2024 or 365 Microsoft Word won't open old .doc Word 3 files from 1989.
Today's Xpress 2025 won't open Quark Xpress 1 files from 1987.
etc.

There are far too many old software programs, platforms, each with their own proprietary file format.
There will never be a "universal" conversion tool.
The closest thing was "MacLink Plus Deluxe" and I bought it, but believe me, it was far from universal.

As a start you should start by making a sector by sector clone of the SCSI drive or your IIsi.
There are some USB to SCSI adapters that work quite well.
If it were me, I would use a machine with Ethernet and SCSI, such as a Powermac G3.
You can use this binary copy of your old disc directly in any 68k emulator like Basilisk.

Then start converting your files.

As for Eudora, the best way to use Eudora's mbox is to use "Eudora Mailbox Cleaner" :
http://andreasamann.com/MacOSX/Eudora_Mailbox_Cleaner

As for AppleWorks, do use LibreOffice and also the batch conversion file from Laurent Godard :
http://oooconv.free.fr/batchconv/batchconv_fr.html
It works very well for all AppleWorks v6 text, bitmap image, or vector image files. But for ClarisWorks 3/4/5 files you need first to convert them to AppleWorks 6 ! Databases files require to be opened in Filemaker up to version 11 I guess.

As for most music softwares, except for exporting to .mid files you have to follow each software upgrade path (e.g for Performer if your old DP performer was a version 3 you may have to first open them in version 6 first, then in actual version 11, because version 11 may not open the version 3 files...).

For BBS conversations and every software who can print in general, your best way is to install Print2PDF programm from James Walker :
https://www.jwwalker.com/pages/pdf.html
I bought it years ago and it is now freeware.
You can set it to automatically export PDF files to the desktop.
You simply run the copy of your old disk in Basilisk emulator, and print every file you need with Print2PDF, then they will be in PDF.

Thank you very much for your detailed reply! I'm well aware the old proprietary software programs. I'll have ot find and try to fire up that old IIsi!

I started with Performer version 1.2! There is no path to opening those old files. DP simply won't do it. Thanks to all the rest!

 

[gilles_polysoft]

Thank you very much for your detailed reply! I'm well aware the old proprietary software programs. I'll have ot find and try to fire up that old IIsi!

I fear that if you didn't started your IIsi from years, it might have leaking electrolytic capacitors whose electrolyte has corroded traces on the motherboard, and worse, if the thionyl chloride LS14250 3.6V lithium battery has also leaked, this usually totally destroy the motherboard...
Always remove them !
And replace with a CR14250 (with no 3.6V IIsi won't start).

Also, the IIsi had old SCSI Quantum disks whose read heads tend to stuck in their resting position (due to a rubber buffer which degrades over time). Simply open the disc (these old discs can withstand being opened in a dust-free atmosphere) and unstick the heads, and it will work again, at least long enough to recover the data.

I started with Performer version 1.2! There is no path to opening those old files. DP simply won't do it. Thanks to all the rest!

Oh yes with all due respect, this is not recent
But are you sure there is not conversion path ?
Performer 1.2 didn't have the sd2 files yet, it was only midi sequencer ?
I'm pretty sure that if you have Performer 1.2 files and transfer them (while preserving resource files) on an OS 9 system with Digital performer 3 to 4.5 it will open and convert them to a newer DP format (or midi ?), and thereafter you can open it with DP11.
