"Warning! Cannot read file plan."

jetthvn — Thu, 30 Jan 2025 10:53:27 GMT

Hello, I was wondering if anyone has a fix for Archicad not allowing you to open shared downloaded files. Files shared between myself and the company architect will allow him to open the same file that I cannot. I have the most recent software update and all the same hardware specs as him. Would anyone know what to do to fix this? Below is a picture of the message I receive:

That error normally displays when you are trying to open it with the wrong version of Archicad. The only way you can work on a file at the same time together is through Teamwork.

Sometimes windows blocks downloaded files. Try right clicking on the file and opening the properties tab. If it has an option to unblock the file down the bottom of the general tab, tick that hit OK and try again.

Still no luck sadly.

As Lee said, the only time I have seen that message is if I was trying to open a file made in a new version with and older version of Archicad.

i.e. the file was saved in version 26 and you are trying to open it in 25.

If you go to the FILE menu > OPEN dialogue, and select the file, you should see the version number of the file.

If you see nothing it means it is a version newer that your currently open Archicad and can't be opened.

Message "Warning! Cannot read Plan file" (Archicad 26 in teamwork)
When user opens the project, in which he worked before (it does not matter yesterday or 15 minutes ago),
sometimes it has the appearing message "Warning! Cannot read Plan file".

Decision, that helped in my situation:
1. We should find out the storage of cache in our computer.
So, Teamwork >Project > Local Data Manager and press "Options" button and check the path to the "Local Data folder".
It looks like "C:\Users\Username\Graphisoft\TW Data"

2. Please, open folder with your cache with path checked in step 1,
choose the folder with projects for example it may be with name like "AC-26.0.0".
Enter in this folder and delete all folders and files in this folder.
Don't worry, it is just local cache, that cause our problem.
3. Close Archicad, open Archicad again and successfully re-join to the project.

I found a solution that worked for me, I hope it helps you. I keep my archicad files in a Google Drive folder for my computer, and I tried everything I could to open the file, but it didn't work. Luckily I had the idea to go to the Google Drive website and download the file directly from there, and to my surprise, the file opened normally, apparently the error only occurred in the file that was on the computer (technically the file was synchronized with the cloud , but for some reason only the computer file had the error). I hope it works for you!

Just another reason not to work directly from a cloud storage folder.

Work from your local hard drive or an network folder, and then when you want to copy the file over to the cloud folder.

If the cloud folder is syncing while Archicad is trying to save, it can cause problems with the files.

I also having a similar problem when project is meeting the deadline, the file suddenly show "Warning! Cannot read file plan."! 😱😰😭.

I m use Archicad 24 to draw the plan, but even I m used the Archicad 27 to open and repair. I also unable to open the file, and it show unknow document version, All the above that Barry has suggested I had tried, but the file is this unable to open and it shows this information. May know who and how to get help ASAP.

Karl Ottenstein — Sun, 14 Apr 2024 02:28:12 GMT

That message may come from (a) being in a cloud storage folder (or a folder that you told OneDrive etc to back up to the cloud), (b) an Archicad crash while working the the file, c) a user permissions problem that re-starting your computer may resolve.

Since it gives you the option of opening Read-Only, did you do that? And then just save it as a new file?

Re: "Warning! Cannot read file plan."

Ian-Pyng — Sun, 14 Apr 2024 09:29:33 GMT

All the file is storage at own PC, we never subscribe cloud storage before. We had restarted many times is still the same. Other files have no problem to open them, only this "Oil Mill Office_231206_R6" file, which we first time insert the MEP ductwork to this project. If we click to the "open as Read-Only". then it will appear " unknow document version"

Re: "Warning! Cannot read file plan."

Ian-Pyng — Sun, 14 Apr 2024 09:38:44 GMT

we also had tried to "launch at new instance of ArchiCAD", then it will show "cannot read plan file."

Re: "Warning! Cannot read file plan."

Karl Ottenstein — Sun, 14 Apr 2024 15:06:27 GMT

The unknown version message will appear if the file had been saved from a newer version of Archicad than the one you’re now using. Newer versions… through 26 can open any old version file back to 8.1. Starting in 27, it can only open files back through version 25.

Re: "Warning! Cannot read file plan."

Ian-Pyng — Sun, 14 Apr 2024 17:32:31 GMT

We had ArchiCAD version 24, 25 and 27, we had tried all of them. None of them can open the file. We had also emailed the file to local dealer to try to open it, but yet to receive any feedback.

Re: "Warning! Cannot read file plan."

Barry Kelly — Tue, 16 Apr 2024 00:41:05 GMT

I am not sure if this will work, but no harm trying.

Open (probably version 27, but you could try an older version) with a default template.

Now 'Merge" the problem file into it.

I don't think it will work though.

When you go to the 'Open File' menu and select a file, it should show the version in the bottom right corner.

As there is no version number in your image, I think the file may be corrupt, or it was saved in a newer version.

But there is nothing newer than version 27, so that makes me think the file is corrupt.

I don't see any BPN (backup) files in your image.

Do you not have the backup option turned on in the Work Environment (you really should).

Barry.

Ian-Pyng — Mon, 15 Apr 2024 11:38:48 GMT

Yes, the PLN. file was corrupted, so as the BPN (backup) file is also corrupt too. We had tried to open a new file and merge too, but it did not work either. Meanwhile we had also used Archicad version 25 and 27 to open it. but it shows the same result.
I have been using Archicad for more than 20 year, since Archicad 4.5, this is the first time I came across the problem. We really like to know what is the cause of this incident, so we can prevent it from happening again.

Hi,

A corrupt object or something interfering with downloading the file, there can be various reason why a file might be corrupt. From the attached picture I can see it still has a lot of information in it. It might be worth to check it's hex codes (you can check it from https://hexed.it/ or if you don't want to do it from an online source you can download Double Commander). Generally, if you see a lot of 0's at the beginning or at the end, that is the most serious data loss, so it would worth to send your file to Graphisoft to be fixed).

The best explanations and solutions you can perform yourself is described in the Graphisoft article> https://community.graphisoft.com/t5/Project-data-BIM/File-Damage-or-Corruption-Troubleshooting-Guide/ta-p/304096

If nothing works, it might worth to contact with technical support.

Selen.

Re: "Warning! Cannot read file plan."

Ian-Pyng — Mon, 22 Apr 2024 07:38:19 GMT

We try the it from https://hexed.it and checked the hex codes as per attachment, We had also contacted the local technical support, but had reply is the file is not repairable. 😭

Re: "Warning! Cannot read file plan."

SelenKovacs — Mon, 22 Apr 2024 08:39:25 GMT

Oh, sorry to hear that. If development says it's not repairable, I don't think you can do anything about it. I would suggest to request the same file from architect who sent it. Maybe they can Open&Repair the file on their side, resave it with "save as..." and send you again. (and/or merge it to a new Archicad file just like how it's suggested to you, save as and resend it).

Re: "Warning! Cannot read file plan."

Ian-Pyng — Wed, 01 May 2024 16:15:56 GMT

Thank for you suggestion. but unfortunately the file is create by me. Therefore there is no other way to Open and Repair. But we just very quercous that the PLN file and BPN will crash is the sometime.
