Sorry for re-asking, but I prefer to better explain my needs, because looking at your other add-ons (Google Drive, DropBox) I think I would be able to handle everything with your WP Media Folder plugin. This is my scenario and requirements:
1. I've several sites using some GB of files (images, pdf, zip files) distributed in several custom created folders via FTP and few items added "normally" into their respective WP media gallery. The files and images "outside" the media gallery was used in posts contents manually, adding the full path (
i.e.
http://domainname.com/myFiles/MyFolder/OtherOne/filename.jpg", etc.).
2. I need to preserve (due to customer's requirement) their custom folders hierarchy.
3. I need, due to restrictions of space in my new hosting provider, to move the actual files outside the ISP to a cloud service (AWS was my first thougth, that's why I've asked about the AWS Offload S3 support but it doesn't honor the existing hierarchy into S3, flattening everything into a single folder. So I can use Google Drive, DropBox, etc. if the previous point's folder structure can be maintained). I've no problems to re-upload the original existing data to GDrive if needed.
4. There is no problem to manually update (or searching and replacing) each file reference (if needed) into the existing posts and pages to the "new file location" if needed, is a one time operation and we're not talking about thousands of posts.
5. The final objective is to have only the WP instalation and the minumum required files into the ISP and the total of the media gallery out of it.
6. I don't need to solve all of this "this morning" but I prefer to take a little time to dig into this in order to have a definitive solution for this sites and futures ones.
Any recommendation will be appreciated and if I can do everything with a single vendor solution like you, it would be perfect. If you prefer to continue this conversation via email or Skype in order to simplify the communications, just let me know.
Thanks in advance!
