Uploading a larger file structure with folders and files hangs. Progress of the upload bar hangs and data is not fully uploaded. The upload has to be aborted.

[chrootENV]

When uploading a folder hierarchy with 3 or more levels and files in each level, the progress bar freezes and the data is not completely uploaded. Finally you can't leave the window, it uploads data until you stop the upload manually.

This bug occurs in the Nextcloud versions 14.x.x and 15.x.x only via the web interface. The desktop client is not affected. This error is very impractical and makes the software useless.

Steps to reproduce

1. Open browser Firefox 65.01, Safari 12.0.3, Google Chrome 72.0.3626.119
2. Upload a folder structure as shown in below e.g

3. The Folder Structure is created but loads infinitely long up to the abort.

Expected behaviour

The folder structure with any number of levels and files must be fully uploaded.

Actual behaviour

When uploading a folder hierarchy with more than 4 levels and files in each level, the progress bar freezes and the data is not completely uploaded. Finally you can't leave the window, it uploads data until you stop the upload manually.

The error can be traced on the following Nextcloud partnerpages.

I agreed.
Problem is very annoying and making Nextcloud web interface pretty useless.
Of course, missing Upload folder option in menu is another feature lack which must be solved. For example, Pydio Cells (and old Pydio) didn't have this problem and have better web interface for uploading files&folders.

[ThePetitJean]

I agree too.

Very big problem for the user...
