What the problem with path lengths? Are you saying that CC or calibre choked on a path? CC is supposed to deal with that by shortening the path components, and calibre is very careful to create proper paths. Perhaps it did that and you didn't like the result?

The download times were less than a second at the start. After 15k or so I noticed a slowdown to about 1 sec per book.
I {believe} the issue with the path length limit is the ~256 character limit for the complete path stored in the FAT32 table. I think that Android may have not liked the path for some reason.
Example: /storage/6144-AD4B/CC Books/{first letter of author's first name}/{Author's full name}/{first letter of the first word in the title}/{title} - {author}. 6144-AD4B is the label for the SD card.
For books with long titles and long author names I got the error message "unable to save {title} - {author}" or something of that sort. This appeared in a gray box and went away by itself. There were only 145 books out of the 24k that this message popped up.
All of the above was while downloading from local cloud Calibre library on the SD card. I tried connecting as a wireless device and downloading the same books from Calibre on the PC. The first book caused CC to disconnect from Calibre without error message.
Subsequently, from Calibre, I saved them as epub in a single directory to root of CC Books with the template ({series}) - {title} by {author}. I then connected CC as a wireless device. CC found the books and downloaded the metadata from Calibre.
EDIT: I tried to recreate the errors but the books download just fine from local cloud calibre library. Some of the 145 had duplicates in the Calibre Library. Some of the 145 had author first name starting with V. CC created folders with both upper case v and lowercase v. Multiple folders V were created V(1), V(2). these disappeared along with their book files. This may need to go into the mystery file unless it pops up again.
