ImpraStorage
ImpraStorage provided a private imap access to store large files
...Once decrypt, it permit to perform search on the server and download each part.
transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. Inversely, a file to upload is split (in several parts with addition of noise data), and ImpraStorage randomly upload each parts then update the index.
