Hi Juraj,
The sketchbook folder is the same place and unchanged.. It is
C:\Users\terry\Documents\Arduino\
There is a library folder in that sketchbook folder but it is not the same as the previous library I had under 8.19 . I have Some older backup copies of my "usual" libraries and I can reconstruct most of it.
The 'new' library folder has the libraries I updated and just 4 out of 50+ of the "old ones".
Where should I report this??
Regards, Terry
But why would this install remove / overwrite my original library folder??
It doesn't help you now but, for the cautious user, release level 2.0.0 of anything is too early for a migration from 1.8.19. It is safer to wait until others discover such problems.
Hi, No.. that's not related I think... The sketch folder and the library folder inside it were at the 'usual' location. Like C:\Users\terry\Documents\Arduino
BUT Maybe: The arduino 1.8.19 CODE is in another location; I have had so many versions over many years that I unzipped new versions in a desktop folder. So I can regress easily. MAYBE there is some local information pointing to libraries there?? Hmmmm...
Regards, Terry
Hi 6V6,
Yes. I am usually cautious but I need to move this computer and myself to Cairo Egypt in 3 days, for the next year. So I was getting stuff "UpToDate"
I can fix this, just some time....
OH: A VACUUM TUBE guy?? March 3, 1956 just after my 16th birthday, started work as "Transmitter Engineer" at WELI, New Haven. 100% Vacuum Tubes from a 1620 (AKA 6J7) Mike preamp to the 833As in the RCA BTA1L. All that stuff came in handy when I worked on an electron beam welder at IBM a (few) years later

There is a libraries subfolder in the Arduino IDE 1.x installation folder. This is intended to be used only for the "built-in" libraries like Servo, Mouse, Keyboard that come pre-installed with Arduino IDE 1.x. However, it is possible for the user to install libraries to that location and you will find some tutorials and library installation instructions that say to do this.
Those libraries installed under the libraries subfolder of the Arduino IDE 1.x will be visible when using Arduino IDE 1.x, but not visible when using Arduino IDE 2.x. So this is one possibility.
Another thing worth noting, though it doesn't match so well with your description is that there is a bug in Arduino IDE 2.x that causes the examples of the older libraries that are missing a metadata file to not be displayed correctly in the File > Examples menu:
Note this is only a matter of how those examples are displayed in the menu. There have not been any previous reports of the loss of actual library files as you describe.
