Not sure if this is off-topic or even "over-topic" cause it involves plenty of non-perl technology.

I'd like to be able to create, edit, update and delete text-files on my mobile device and to keep them synchronized with a folder on my desktop computer.

I'm not sure about the easiest way to achieve this:

Here some brainstorming:

• using an email client and storing the text as drafts and using Perl to synchronise the folder
• synchronize text-memos with google-drive, and access that web-folder via Perl
• trying to figure out where text-memos are stored in the mobiles file system and trying to synchronize that folder directly
• trying to find a browser-app which can access local html-files¹ and allows to change and safe them somehow
• using some third party app
• something I didn't think of yet ...

¹) this would be handy cause I could implement some JS logic in DHTML too, but the standard browser doesn't even support the file:// protocol
