This app is dangerous! Don't use it!
Sadly, I used it to access my S3 drive. I created a new bucket and I moved thousands of files from another bucket to this new bucket. Expandrive did not moved my files into the target bucket at all, and it DELETED all the files from the source bucket!!!
Because of this app, I lost terabytes of data...
I reached out to the support and nothing.... they are literally doing nothing. It's been over a month since I raised this issue, and I haven't heard back from them...
It's the worth app I have ever used, paired with the worst support service.
