File type not correct
« on: February 12, 2018, 02:57:52 PM »
I have an old Mac that I use once a year during tax season to run Quickbooks Pro V5. This year, when I turned on the computer the date was set to 1956, so I must have a dead battery. After resetting the date, I found I could run Quickbooks but the associated data file is not recognized anymore as a Quickbooks file. The file seems to be there and is over 5M in size and shows an access date of Feb 2017, which all looks correct.  But the OS seems to think it is a generic "PC file" type. Can anyone help?

I assume it's not just a question of double clicking the file, but that you can't open the it from Quickbooks either, which may mean it is corrupt.

Did you try booting into OS 9 with the Command-Options keys down to rebuild the desktop?

If the file is corrupt, this probably won't help, but it can't hurt either.

If I open the file from within Quickbooks, Quickbooks says it is not a valid QB file. If I double-click, the OS tries to open it with a CAD program instead of with Quickbooks.  I made a backup copy last year on a ZIP drive, and it is behaving the same way. Doesn't seem likely that both copies are corrupt.  No I have not tried to rebuild the desktop (did not know of this).

if the desktop rebuild doesn't bring back the info (correct icon), you may create a dummy new file and check it's file type and creator with a utility that shows these properties (Filebuddy is a convenient one). Then edit your old file info and enter those values.

I did the desktop rebuild and it made no difference at all. I guess that editing the file info is the only other thing to try, but that won't be easy since this computer is not on any network, and I don't have a networked computer with a 3.5 inch disk drive or zip drive to transfer files. I will have to plug in an Ethernet cable and try to get connected.

I found the problem and I had completely mis-diagnosed what had happened. When I started the computer earlier this month for the first time in about a year, the date had come up to some time in 1956 or so and I couldn't open the Quickbooks files.  I have restarted it about a half dozen times in the last two weeks and it always booted fine on OS9. Today, I was trying to run a version of Netscape (the only browser on the machine), so I could hopefully download a new browser and then Filebuddy. The machine crashed (froze), and upon power-cycling it came up on OSX (10.2.6) from, I believe, 2003. Everything (Quickbooks, the only application used on this machine) worked fine - the datafile was accessible.

Not sure I really know why it started on OSX today, but my problem is solved, at least temporarily. Could this be related to the dead battery/date problem or is it likely to be something else? Any thoughts?

YES.

It appears that this was not a dead battery either. It looks like after something caused the machine to boot to OS9, then slight differences in the file properties caused the Quickbooks datafile to be unreadable as well as the date/time. Whatever made the machine startup on OS9 was static for weeks until a crash, after which it booted on OSX (10.2 Jaguar) where everything is back to normal. Even the date/time is set accurately (which I had never manually reset on OS9).

Any ideas on what really happened? Or how to prevent this in the future. Can I delete OS9 from the machine entirely so it can't ever boot there? Or some better idea?  (Since I won't be using the machine again until tax season next year, I may forget again what the correct OS version is. Although going through this this year will probably make me remember.:)  This machine will stay on OSX 10.2 as long as it keeps working.)
