Hi Kovid, on migration to another computer I used the Export/Import function, which works in principle very well

I really liked it to find all my settings and saved searches.
However (there is always an however

) I encountered some points I like to have clarified.
- On export, I choose the top directory of an empty USB-drive.
Calibre refused to use it as it was not regarded as an empty folder. Creating on the USB-drive some empty folder solved that, but it might confuse the average user.
- On import, calibre correctly informed me the saved directory structure, but refused to restore them. Only when I manually made these directories in the destination drive/folder, all calibre directories were restored. It should be more straightforward that calibre suggests to create those known original directories, unless the user decides otherwise. Again it might confuse the average user.
- After restoring, I noticed a difference in the shown library structure (see attachments: left original, right migrated). The migrated libraries now show also the library path, while curiously also the same libraries without path are shown. My question: is this correctable?
I used calibre 3.30 32bits (source) and calibre 3.30 64bits (target).
