Hello, you first need to select a target directory on the left side of the file transfer screen before the Download button becomes available.

It would be better to discuss this in a new thread or by email (support@textasticapp.com) as this topic is specifically for problems with Synology devices.

A screenshot of your connection settings and log files (Textastic log and server logs) might help.

Untitled files are stored in iCloud if iCloud is enabled. Please check if you have untitled files in your iCloud and delete them if you do not need them anymore. This will reset the counter.

I'll try to reproduce it with the app you mentioned. Is it this one? https://itunes.apple.com/de/app/mega/id706857885?mt=8

Hello,

the Inbox folder is created when you use "Open In" to open a file from another app in Textastic. Unfortunately, in recent iOS versions, once created by the system, this folder can't be deleted by the user. I'll consider hiding this folder in future releases of the app.

Textastic moves files from the Inbox folder to the root folder and tries to delete the Inbox folder (which fails since iOS 7). In earlier iOS versions, the user wouldn't see the Inbox folder at all.

I haven't seen the Cocoa error 513 issue before. On my iPad I can edit files that were imported with "Open In" (and are now in the root folder) just fine. I just confirmed this by opening an HTML file from the Dropbox app in Textastic and editing it. Which iOS version are you using?

I don't plan to change the icon at the moment, sorry.
