What's with this file that always appears in almost all my folders that contain pictures on my Mac?

I am having to delete it time and again :(

Those are thumbnails generated by MS Windows when you share folders with a Windows machine. They will be recreated each time a Windows machine accesses the folder.

If you want to disable the creation of the thumbs.db on network shares, edit or add this registry entry:

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer]
"DisableThumbsDBOnNetworkFolders"=dword:00000001

I have this set on my Win7 PC and no longer see the thumbs.db cache files.

If you're not familiar with editing your Win7 registry, google it and heed the warnings about messing around in the registry. Only edit what intend to.
