The Dropbox API doesn't offer a call to append data to an existing file, but I'll be sure to pass this along as a feature request.

You'll need to upload the full contents of the new version of the file instead.

How to be notified of the new release?

I'll make a note to follow up on this thread if/when this feature is implemented and released.

@captain husayn penguin There's no news on this feature request currently.

hi there,

I am new to dropbox and looking at the options offered for file sharing, i wonder why there is not an append to file one. Why ? when people from a group modify a document (write) some information may be deleted. When appending to the document, the owner can see what was added or requested to delete, and then the owner can aggregate all the comments to finalise the doc.

I'm looking for this opportunity too. I need to add batches of jpeg frames to a video. And I should be able to watch video any time. If recording frames separately there will be many files.

I think it might be upload_session. You just need the file to be available immediately throughout the upload. A 12 hour session is enough for me. One day would be optimal. File within 50 mb. Rarely up to 200 MB.

The Dropbox API still does not offer the ability to make a new version of a file by just appending data to an existing file.

The Dropbox API upload session functionality does offer the ability to upload files by sending multiple requests, each with just a portion of the total data, but that still requires the app to upload all of the data of each new version of the file. And while each upload session can be kept open and used for up to 7 days, it's not possible to access the data that has been uploaded to the upload session until the upload session is closed/finished.

You wrote about to access the data ... but how about access to a copy of the data? Can you copy current data to a file in user folder. This will be a file with a special status. As temporary. This can be done not often. 1 time per minute if the data has changed for example.

@md22 No, the Dropbox API does not offer a way to make a copy of the pending upload session data like that.

Sounds good

Who make Dropbox API? 🤔

Greg-DB

@md22 The Dropbox API is made by the company Dropbox. The Dropbox API does not currently have the functionality requested here, but I've sent this along to the relevant team in the company as a feature request. I can't promise if/when that functionality would be implemented and released, but I'll follow up here if/when I have any news on that.

Sounds good. Thank you!
