Migrated to new computer. Used backup and Restore. Somehow I am seeing duplicate XMF files sprinkled throughout a majority of my restored folders. I have run the Elements application after the restore but haven't edited anything. Noticed when I did a large compare of files on old vs new machine. All the "new" XMF files are <old_name>-1.XMF and so far are identical to previous version of XMF files that I have looked at more closely.
Anybody have a clue why this happened? Think it is safe to delete the newly -1 versions?
No user error according to your description. The duplication most probably took place on a restore or import session. It regularly happens to find duplicated media files with the -1 suffix (not -1.xmp suffix) during the import process (also probably in the restore one) and the files are already in their import folder. The files are imported and renamed to fit in the subfolder even if the downloader recognizes the files are already in the catalog and does not register them in the catalog. You get a message telling you which files have been skipped from the import, but even if the catalog is exempt from dupes, they are in the folders. It's the first time I see those duplicates for xmp sidecar files. New edits should not create those duplicates. What is your OS version?
