TXT files), passing it the full path to notes.txt.
Its contents have not yet been downloaded to your computer. Suppose you have an online-only file called “notes.txt” in your Dropbox folder. The arrangement is fairly technical, but the following example illustrates the basic concept.
Synch dropvox driver#
When you access a file in your Dropbox folder, demanding to see its content, a Windows Minifilter driver ensures that the file’s contents are quickly fetched from. Windows file system Minifilter driver technology Very efficient!īut what happens when you try to access the zero-content file? That’s where the next technology comes in…Ģ. As a result, you can see the file on your system but it consumes almost no space on your hard drive. So when you create a file on, the file’s information (its “metadata”) is immediately downloaded to your computer but none of the file’s contents are transferred in that operation. NTFS Sparse File functionality allows Dropbox to create an “empty shell” for any file - with all the usual information (name, size, etc.) but with none of the actual content. Smart Sync leverages a trio of Windows capabilities: How Smart Sync works: Supporting technologies If you can recommend a more suitable forum to discuss this I'd be happy to take the conversation there).Indeed, Smart Sync has been a very popular feature since its debut in 2017. (note to mods: I realise this may be deviating somewhat off-topic - sorry about that. Would this be of use to you? Would you (or any others) be willing to participate in such an effort?
Synch dropvox code#
I've actually got some code already (which I haven't publicly released to date) but could use that to get the project started. I've actually been recently considering starting an open source project to develop a library which can connect to all the major services, and provide an abstraction layer that papers over their differences, and also handles the syncing process for you.
Then there's also all the issues of conflict resolution (aka merging) which come about when multiple clients try and sync conflicting changes to the server. For example Dropbox's API references files according to their path, whereas Box's API references files according to their file id (which has an associated path, but I believe remains the same if the file is moved). In my case I've been starting to add support for additional online storage ("Cloud") services to my app, and am finding that it's somewhat challenging to deal with the differences between them in how they handle various concepts like authentication, version, naming etc. This will probably suffice if you're just working with dropbox. As ohho mentioned, there's the DropBox Sync API available now which I think will do what you mentioned (I haven't tried it personally, as I integrated support for Dropbox in my app using the earlier SDK, before this came along).
