Emulation
This app works with: Mini vMac

FEdit is file and disk editor that was popular in the early years of the Mac. Its uses include examining the raw contents of files, recovering data from damaged disks, and modifying applications to disable their copy protection.

DL #1 includes a bootable disk image containing FEdit 3.5 (©1985, registered shareware) and FEdit Plus 1.0.7 (1986, commercial version published by MacMaster Systems).

We'd love it if you could upload any later versions—FEdit Plus 1.1 and 2.0 were supposedly released.

The manual (linked above & below) not only covers FEdit Plus, but also goes into 26 pages of detail about Macintosh disks themselves, from their physical structure, to the MFS and HFS formats.

The source code of an early version was made available online in 1984.

Compatibility
Architecture: 68k

Note: The Manuals (either of the above PDF's) have typo errors in the "Table of Contents" listed under "The Hierarchical File System".

md5: 3ed0793b92196f5f38cf22c71b46e4f2

@SkyCapt: I must apologize, as I reported an incorrect MD5 checksum earlier, the one you are getting there is the correct MD5. - I'm thinking I must've reported the checksum to one I had already altered in Acrobat. A mistake on my part, sorry.

About the resource fork. PDF docs don't have one to worry about, they need to be pure data for portability across networks.

Something's still wrong. The 2nd "flattened" conversion PDF works, thanks for that. But the original manual scan: I found a download button for PDF on chrome's toolbar, but it makes me the same bad file, 2269820 bytes size, md5:
3ed0793b92196f5f38cf22c71b46e4f2

I get zero resource fork due to the unwrappered move across msdos filesys, is this a matter of lost resource fork? If there was a resource fork, is it getting dropped or is it getting tucked into the data fork? I'm keeping this file in my miscellany folder as an example of PDF that crashes OSX Preview.

md5, that's not the md5 I got. My download process is flawed

Yes, If there are files I want to keep, I prefer to DL files and docs to disk in the condition as uploaded, so intermediate "helper" apps don't get the opportunity to alter original bytes.

md5, that's not the md5 I got. My download process is flawed, the way I've been getting PDF from here is it Opens in the browser when I click on their button, then I direct the page on its desktop to Save, so this thing I've been doing is likely distorting my PDF files. I was transferring them from google chrome on windose to my macs, Macs aren't networked. I think I've seen a varying degree of sluggishness on many PDFs in past years and this particular one was very pronounced and made a good example to dissect. In the end feels like a bug in previewer (or chrome/windose) that certain benign data can choke a viewing experience.

We could have a second alternate button with a flattened manual

@24bit: Done. - One thing in the flattened version's favor I suppose, is that it's 68K compatible. I recreated it from PostScript using Acrobat 3 & Distiller 4, I also added Bookmarks + page links to it's Table of Contents, so this may help. Don't know if its going to be any faster loading tho' and its a pity about losing the OCR'd content.

Would be nice if simply my download was corrupted

@SkyCapt: As I haven't struck those issues you're getting, if it helps, the MD5 checksum for the manual as I DL'd it is: 000ea5697089e1af2463db5a08f09ed1 *fedit_plus_manual.pdf
I'll also add the flattened version I created to the page.

[Edit] My given MD5 checksum for the Top DL manual was incorrect. Apologies to all.

Actual is: 3ed0793b92196f5f38cf22c71b46e4f2 *fedit_plus_manual.pdf

We could have a second alternate button with a flattened manual with explanation about that.
Mike will be kind enough to add a flattened file for sure.

I see. This has me curious, I viewed this on a 2nd mac now, a dual core 2.4 GHz x86 running OSX 10.4.11 and it is even worse than my PowerMac and it never settles down no matter how long the wait. Would be nice if simply my download was corrupted but I doubt it given you couldn't open it in Acrobat 4 when it should have opened. What could allow others to get no speedcreep from this? By slow I mean when trying to flip thru viewing +/- 1 pages quickly. Both my OSX installs are very "fresh" and low frills, one x86, the other PPC-only made from pre-Universal. I've ATI gfx in both machines, but I doubt Nvidia makes the difference.

If you can make it into a better file that's not huge, how 'bout replacing this one...

Please don't. I would be very reluctant to replace this, as the "Adobe Acrobat 9.45 Paper Capture Plug-in" device that created the above PDF had also OCR'd the scans. It didn't embed fonts but the OCR'd text info is in there. Converting this PDF to PostScript and back to PDF again, the text is omitted. - its not transferable.

So as is, the current PDF has text that you can copy and paste into other docs, but with conversion the PDF gets flattened and that OCR'd info is lost. That is, I couldn't see a way of saving it in the conversion process.

I have a one-core CPU at 1.5 GHz

My test Mac's for this was a 300MHz Beige G3 running Acrobat 4 on Mac OS 9.1 and 1.33 GHz iBook G4 running Acrobat 5.05 on OS X Tiger. No noticeable lag in reading the above PDF in Acrobat 5 and the converted PDF in Acrobat 4 & 5. Admittedly it was slightly slower on the beige, but this is to be expected and it wasn't uncomfortably sluggish.

If you have the full version of Acrobat 5 on OS9, try printing the PDF to a .ps file (PostScript) then use Distiller (set to "Print") to print the .ps file back to PDF. If you don't need copyable text this may help speed things up for you. My results produced a good quality PDF of approx. 2.6MB.

I suppose it goes full speed once it is done chewing on all the pages, and the slow period is not sooo bad on my OS9 Acrobat (5.1), I probably wouldn't have mentioned it if I didn't first see how much worse it is in my OSX Preview (Tiger). I have a one-core CPU at 1.5 GHz, so you guys with 2 cores doing over 3 GHz might not notice. If you can make it into a better file that's not huge, how 'bout replacing this one...

Odd that it doesn't open in version 4 Acrobat being a vers. 1.3 PDF. Doc was created in 2011, but that wouldn't have any bearing on it not opening in vers 4.

As an experiment, I open it in version 5 Acrobat and printed the file to .ps (PostScript) and wrote it back to PDF using Distiller 4. It created a PDF that was compatible with version 4 Acrobat and the file size was 2.6MB. That worked OK.

Same here Mike.
The manual displays fine with Preview 909.12 and Acrobat Reader DC 15.23.20056.213124.
The pages are rendered a bit slow with Preview it seems
macOS Sierra says the document was made by Adobe Acrobat 9.45 Paper Capture Plug-in.
Probably round about 2001?

No problems with it here. The PDF itself is version 1.3 (Acrobat 4) so should be correctly viewable on version 4 or newer of Acrobat, OK.

[Edit] I do have a problem viewing it in Acrobat version 4 on Mac OS 9.x. It fails to render the document and exits with the error message "There was a problem rendering this document (9) [OK]" then exits.

No other issues tho' with Acrobat 5.x so far. None of the lag you're describing with this PDF, is happening for me here.

The PDF manual bogs down real slow, chokes both OSX Preview and OS9 Acrobat. I can get it (the PDF no kidding) to run fast if I resave it in Preview, but then it grows from 2.1 MB to over 7MB. If I choose the small size option it "only" grows from 2.1 to about 3.5 MB but the quality smears too much to go that route. Even 2.1MB seems too large for just a bunch of typewriter pages. What's wrong with this PDF, is there a name for this? Viewer speeds up some if you give it a while to chew on all the pages but that can take over a minute or two.
