So the folder "My Digital Editions" is installed by ADE and it is ok to remove this folder and the contents?
I had only borrowed library books, all read, in My Digital Editions. Bought books are all stored at KOBO. The other sub folders in MDE are:
Annotations
Manifest
Restore
Tags
Thumbnails
Then there are 3 files Import.log, manifest.xml and migration.log
Where are all these .acsm files? I notice under Adobe / Program Files there is a folder called "Reader".
Think I'll call the computer guy in the morning, this is too dangerous for me.
I appreciate all your help, thank you very much.
