What is the problem?
I have a problem with the JS code here
When I run AR, and open and save and load tabs everything works.
However when I open AR and try to Load Tabs, all pdf files are nonexisting.
It works for me.
Now I've found a partial solution and deteceted the problem.
The problem occurs only if I donwload to DESKTOP. If I download high enough in the hierarchy of files,
namely to subdirectory of D:\
the problem doesn't appear. I Don't know why, but I'm happy with this.
