I used Picasa to edit my photos and found the face recognition element especially useful to help identify faces in older family photographs I'm starting to scan in.
Whilst I did eventually find my old pictures (in their sub files), via explorer, in W10 - I didn't have Picasa and I'd lost all the extra data.
As I was not expecting this (others seemed to have transferred over from W7 to W10) I was totally 'thrown' by the experience. To be presented with my photos only in date order and been told by the 'computer person' to "just get on with it - Picasa is obsolete"; did not help.

I do have my photos backed up on a separate (external) drive, but the additional information was only within Picasa.

I will investigate the alternatives you have suggested, but as is apparent I don't know much (if anything) about computers and cameras I will probably retire from the forum and continue my life as a dinosaur.

Many thanks for all the comments and suggestions. Some of the information I discovered independently, but a friendly comment never goes amiss.
To restore my equilibrium (if not that of the computer installer) I have today had my W7 computer rebuilt. The situation now, is as if W10 had never happened. This may only be a temporary resolution, but I will continue to search for 'up to date' alternatives to Picasa.

help.
On being 'upgraded' to a W10 OS computer I seem to be having a problem. I have an old I-10 compact camera.
My mediaImpression 2.0 software has disappeared and the 'F drive' which I now have to use just keeps saying 'you have a problem'. I don't want to press any buttons that might format the camera card. As I 've already lost all my Picasa data, it would too much to loose my new pictures as well.
Yes, I know, I've been called a dinosaur many times, but what can I do to fix these problems?
