Re: Opening Psion 5 files in my PC

You need to transfer them using PsiWin - it will automatically convert the files p[roperly between PC and Psion versions.
You cannot just transfer the files via i.e. the CF card and expect them to work.

I believe versions of AbiWord can read Psion Word Processor files directly but have never tried this myself.

Unable to move files from Files to the screen.

Thank you for your prompt reply to my request.  I have decided that the blocked files are too complicated to sove by  telephone and have, therefore, sent my PSION S3c to POD Ltd in the UK.   Regards, Peter Whiteley (uncle peter)

Psion Revo replacement restore

What do you do if you no longer have access to a Psion, but need to access some data from an old Psion backup on your PC? Native Psion files can't be read on a PC, but fortunately, there are some solutions:
  • Use the PsiWin PC connectivity suite to convert the Psion-format files to a format that can be read on the PC.
  • Download and install the Psion ER5 emulator - this gives you a Psion machine on your PC, and will allow you to access your old data on a PC - See our emulator setup page. From the emulator, you may be able to print or export your data to a text file, or use a third -party Psion converter
  • Consider borrowing or buying an old Psion machine, loading the files onto the Psion, then printing the documents or data as a text file
  • Find another friendly Psion user that may be able to convert the file into a format that can be read by a PC for you. If you don't know of another user, try asking for help in our Psion forum
Data conversion for the Psion can be quite complicated, due to the file formats used by Psion / Symbian. You should find that the PsiWin program supplied on CD with your Psion machine can help you with most of your conversion needs. If your PC is connected to your Psion, dragging files from "My Psion" to the PC should prompt you to convert to a PC format, otherwise you can convert files that are stored on the PC, using the Psion File Converter. This program is installed with PsiWin and is located in c:\program files\Psion\PsiWin - the application filename is Cpycnv.exe
psiwinconv.jpg For more help on file conversion, see our dedicated conversion page.
Agenda and Contacts databases: Note that these can't be converted using the Psion File Converter - PsiWin supports synchronisation of these files, but not direct conversion. See our suggestions in our Backup FAQ. The most common solution is to load up the files in the Psion Emulator, and either use Print to save the data as a plain text file, or use a Psion-based converter, as detailed on our Conversion page

Connecting Psion Series 5 with Mackintosh

MacConnect was written for MacOS 8 and was discontinued in 2002. The last version it supported was MacOS 9.

For MacOSX, use the Java Psion Link or JPL. This is platform independent and works with any java enabled OS, which is pretty much everything nowadays.

Psion 5Mx

Only suggestion here is to try a cold reset. Make sure you have an up-to-date backup. Take all the batteries out and leave for a couple of hours. Re-install batteries and check the Psion. If all looks good, do a restore. If things look bad again, your system was corrupted so reset again but do not do a restore. You will then have to trial-and-error reloading parts of the backup.

I would suggest re-installing any third party software from scratch.

Psion 3mx connection problem

Searching Google for 'Plat 46' i found the following stuff on the Debian website (via google cache... but this may not hold good long-term as a link as the cache will change in time).
<Extracts from Debian site>:-


Thus the reported plat:46 means ESystemException. The problem will very likely be resolved by restarting the app or the emulator.

These alert boxes shouldn't happen - they are typically associated with unexpected errors from underlying Win32 APIs, or some other indication that the emulator has got itself into a state which makes no sense in terms of EPOC: for example the EGuiStandbyWhilstOff message which happens if the emulated EPOC system is switched off while it is switched off (?!); or a needed dll is in use (being rebuilt?) when called.

</End of extracts from Debian website>

The debian page is not directly related to Psion 3 series, but there's a good chance that their error-code enumerations hold good for the message that you're seeing.

So - putting this back into the context of your failing Psion3mx connection attempt - it is likely an issue between the PsiWin software and the Win OS dll's that it is using.

Assuming that you used to be able to connect your 3mx and this problem has started happening recently. I also assume that you have already tried closing PsiWin, restarting your PC and trying again (if you haven't then try that). If you've already tried shutdown and restart and you still get the problem each time then perhaps the PsiWin software on PC needs reinstalling. Maybe a .DLL file got corrupted or deleted somehow.
I suggest you make backup copies of any data from your 3mx that is stored on your PC first though, if you decide to try reinstalling PsiWin.

As I don't know your level of experience with your Psion 3mx and PC, I am posting this purely to try and help 'shed some light' on the problem as you request. I have not had this problem with my Psion so have no 'tried and tested' answer.

Any decision on if and how to proceed in the light of this missive i've posted (and therefore any consequence of any decision) must be down to you.

Hope this helps you to figure out your connection problem and get your psion 3mx working with your pc again.

Psion 5 fc card

The formatting is supposed to be identical on Psion and PC but in practice they are not. You should never try to repair a CF card on a PC for instance as it messes with the filesystem making it unusable on the Psion. Try to format the card on the Psion if you can, or if possible find or borrow a camera which takes CF cards and use that to format the card - that should do the trick.

Transferring files w/o conversion?

You are going to have to use a SD reader/writer to transfer the files from your PC to the SD card and then you can use it that way.
