[?]: Help on Error (256:145)

Post by Coyote » Thu Jan 24, 2008 10:12 am

I was working yesterday on a project.
I have saved the project on two different locations for backup.
I have made some mainteinance tasks on HD and I am unable to open project, while I'm able to open older projects without problems.

The project or library was changed using tools of Windows Explorer.
The data for access protection has been modified to such an extend that is no longer possible to open the project or library.
Does anybody know what is going about and how to solve?

Hi

Gratulation.

Your tool has delete 0-byte-Files.
In Projekt they are many Files with file-len with 0 Bytes.


I hope, you have an backup from your Projekt.

You can try:

Make an new Projekt.
Copy diverent file from your Projets that not work in it.

I have made the backup on the same drive, but on other partition. There are also other projects that could be normaly opened. I have uploaded the project from PLC and now I dont have symbols.

I would like to copy some files from death project to a new project but I dont know which one, there are so many folders. I would like rocover at least symbol list and some datablock with names.

Please help.
