Cannot save because the document is read only

[Floriance]

What is this? I opened my existing Affinity Designer document what I have modified every now and then. Now, today I could not save it because it is read only. How did that happen? Of course, I saved it with a different name, but I would like to know what is this read only thing and why. I am the only one who use this computer.

Check while in the Finder using the Get Info about that file. See if it is locked.

Or it could be changed down at the bottom.

 

The change at the bottom can happen if you are in a different User account. My setup is that day to day (99.9% of the time) I run in a User Account (without Administrator Privileges). It is possible to create files in a User Account that will not be Read & Write for another User Account.

I checked all those are ok. Not locked, and I have rights to read & write. But, the strange thing is that now I can save. Seems that it was some temporary mystery. I opened again that same earlier document (not re-named), and now I can save.
