Thanks. That pretty well confirms that what I just did should be OK. But I looked for the backup file on the PC, for further confirmation that it exists, and did not find any. I assume the file is somewhere else, in Apple's file warehouse in the "cloud."I would rather have it here but this is better than nothing. :-)
I replaced my iphone 6 and could not transfer data to the new 13 because the battery in the 6 was dead. Now I have replaced the battery and the 6 works but it has no cell service; that is transferred to the 13. I can connect the 6 to the PC and transfer photos (most of the photos were saved in the cloud and eventually (with some help from Apple) we convinced those to migrate to the 13). I have a lot of stuff I wrote in "Notes" and I always wished I could back those up on the PC same as the photos; but, so far, Windows Explorer can't see them. That is what I would really like to do now, but:
I found a work-around for that, I would email a file from Notes to my email account and when that worked OK I could read the text on the PC. If I can get cell service temporarily, I can take care of the Notes that way; I will talk to Verizon about that if there is no way to transfer the files directly as described above. I also tried placing the 6 close to another iphone to see if they have a way to communicate without cell service, but if they can do that, I have not found out how, so far. I have 61 years of experience with computers, but that does not mean I can always make them behave. Help?! :-)
