My setup is as follows:
Now I get error messages when trying to open various files on the PC from a laptop. The error messages or the faulty results from opening the files differ depending on the type of file (PDF, XLSX, JPEG, ..).
This is not consistent, however - at least not to me: some files can be opened without problem (TXT), other file types show even more mysteriously varying behavior: I could open one XLSX file, but got an error opening the next XLSX file in the same folder.
Going to the PC I can open all files regardless of file type without any problem.
I copied the files to a USB stick, then from the stick to the laptop: no problem opening the file.
I accessed the file (now on the Laptop) from the PC and from the other laptop: no problem.
I therefore conclude that the files per se are not defect as they can be opened on all computers.
The problem seems to be the access from any of the Laptops to the PC only, not in the other direction and not between the Laptops.
I'm now going to set back the PC to June of this year using one of my backups. I'll keep you informed ho it's going to work out.
