Binary files are greyed out. You can tap on it anyway and try to open it, but if it is not a proper text file, it probably won't open.

What you can do is the following:

- Download the site to a folder

- Create a copy of that folder which serves as your backup

Thanks, I reported this problem to the userecho guys: http://feedback.userecho.com/topic/144783-you-had-already-voted-when-tapping-on-the-vote-box/

Please try to tap on the "up" arrow above the vote box to add your vote. This should work.

Thanks for the test account. I could fix the problem. Here's the reason:

In order to show the overwrite prompt, Textastic first checks to see if the file already exists on the server. This check left the file opened on the server. 

On Linux SFTP servers, this isn't a problem and the following upload of the same file works. Bitvise SSH Server or Windows itself seems to block the file and the upload fails.

I could fix the problem by properly closing the file after the check for its existence. It will be fixed in the next update.

Connections are closed after each file transfer (upload/download). If you are just browsing directories, the connections are kept open to speed up the process.

You can set the maximum amount of concurrent connections in the connection's settings screen - the default is 3.
