Project-file gone, but all base-files still present: Can it be restored?

[SvaneSDU]

Hi everybody
I've just opened my project folder on a very large project, at to my horror i realized that the project-file (PSX) was gone. I don't know what has happened as I haven't worked on this for a while.

All the 78GB of project base-files are there though. Is there any way of restoring the project from these?

Any help would be very much appreciated!

Kind regards
Niels

Hello Niels,

Do other important files, like project.zip, chunk.zip and frame.zip are present on lower levels of the project.files folders structure?

Hi Alexey
They seem to be present yes.

Hello Niels,

You can create the psx file with the same name as .files folder with the following lines in it and try to open the project again:

Code: [Select]

<?xml version="1.0" encoding="UTF-8"?>
<document version="1.2.0" path="{projectname}.files/project.zip"/>

[SvaneSDU]

Sorry to ask, but how do I include the lines in the project-file? I rarely use the console in photoscan if that*s the way.

Hello Neils,

Create new text file, copy these to lines to it, save and then rename from txt to psx.

It says xml syntax error. Too bad, when knowing all of the other project files are still there but cant be directed.

[SvaneSDU]

I missed one ", but now it says: Canøt open file as the path wasn't  found.

Hello Niels,

Does it say that the syntax error is in PSX file (usually more informative information is in Console pane)?

Alternatively, you can create a new project, save it in PSX format and then copy PSX file and rename it according to the .files folder.

[SvaneSDU]

It seems that the project.zip is empty of any information, thus it of course can't open.

Hello Niels,

project.zip contains doc.xml file (always the same name) with the following lines (according to the number of the chunks in the project):

Code: [Select]

<?xml version="1.0" encoding="UTF-8"?>
<document version="1.2.0">
  <chunks next_id="3" active_id="0">
    <chunk id="0" path="0/chunk.zip"/>
    <chunk id="1" path="1/chunk.zip"/>
    <chunk id="2" path="2/chunk.zip"/>
  </chunks>
</document>
"next_id" should be always larger than the bigger id of the available chunks, whereas "active_id" should be one of the available indices.

[SvaneSDU]

It also looks like that, just with the one chunk in the project.

[SvaneSDU]

Regarding the error message, it says: Error: Can't open file: The requested path was not found (3): Data/Præstø_Strandeng/Projektfiler/{100m_total_korr}.files/project.zip

Hello Niels,

The PSX file should contain exactly the following lines, do not edit the path to the project, it's fine that it is {projectname}:

Code: [Select]

<?xml version="1.0" encoding="UTF-8"?>
<document version="1.2.0" path="{projectname}.files/project.zip"/>

[SvaneSDU]

Thank you so much!

I can't stress how important it is that you guys always help so quickly.
This is really why we use Photoscan instead of other software solutions.

I hope that we can provide input/feedback the other way as we use photoscan intensively in the university and will begin teaching using it next year.

Thank you again and have a nice day Alexey!

Regards
Niels
