Server: Add option to copy/duplicate files

[agoat]

Currently there is no possibility to copy a file to another (or same) folder in the WebUI. Files can only be moved to other folders.

Usecase 1:
UserA shares a file with UserB. UserB want this file in his own file storage (on the same server), so UserA can unshare and delete the file and UserB have it for his own.

Usecase 2:
UserA want to share a file with UserB but also give him the option to edit/change/delete the file. But UserA want to save a copy of the original file (in another folder).

This will be greate when this will be possible.

Another Usecase:
A Templatefile (Business letter as Word Document) is shared as read only for all users. All users can make a copy of it in Webgui for his own use and write a business letter for a customer for example. In this example we have a lot of Template files for many situations.

This would be important! 👍
I am quite often in the situation that I want to share documents with my fellow students, but they don't need to get everything that I add to the document afterwards 😛
And I always want to share single documents from a seperate folder that I can keep track of what I shared!

Design-wise this could be nicely integrated with the move function. We simply need to rename the function in the dropdown »Move or copy«:

And in the folder picker which gets opened we simply need to add another button for copying:

Move will be the primary button, and copy a normal one. For better feedback, the copy and move buttons include the current folder in the text. Like »Copy to Pictures« or »Move to Pictures«.

Do you think something like "Cut" could be implemented as well? For now it is still a two step operation:

• Move file(s) to new place
• Delete old file(s)

Another question: Does this implementation work well for moving/copying huge amounts of data? In the past it was basically impossible using a browser to do that because of synchronous operation:

@e-alfred the »Move« operation does move the file, that is cut & paste. There is no need to delete the old file. Just confirmed with latest master.

@jancborchardt I mixed that up, sorry.

But the second question still stands. How well does it work with a huge amount of files?

There is no need to delete the old file.

This would be the worst case for Comments, Tags, and Versions.
