When having such issues please always disable 3rdparty apps before reporting any issues. In your case the issue is most likely caused by:

That 3rdparty app is known to be broken since ages. Because of this it is also breaking the gallery as seen e.g. here:

Indeed, it is the same error as I reported in 9.1.0

However, a patch was submitted by oparoz in the mentioned issue ( I assumed it was integrated already.

To be honest, I'm a bit confused:
files_mv is delivered out of the box - then it should work. If a patch is provided by someone fixing isues (see link above), it should be integrated upstream. If OC devs decide to abandon files_mv then they should remove it.

Don't deliver apps in a dysfunctional state.

It is the second time I stumble of the issue. If I deactivate files_mv, what is the recommended/OC-ish way to move files or folders through multiple folder hierachies to now locations. Currently I'm only aware of files_mv to achieve that.

Thanks for your help,

files_mv is a 3rdparty app developed and provided by a 3rd party app developer. It is NOT provided "out of the box" or delivered by/with ownCloud.

The fix by @oparoz was submitted to but it seems the app developer of that app doesn't care.

Additionally to this the app is only shown when "experimental apps" are enabled where you get a big red warning in the app list:

Experimental applications ahead

Experimental apps are not checked for security issues, new or known to be unstable and under heavy development. Installing them can cause data loss or security breaches.

The big red "Experimental" button besides the "Files move" app is also showing:

This app is not checked for security issues and is new or known to be unstable. Install at your own risk.

+1 for you: It is marked as experimental.

ah, is the "apps" page a online repository? Then you may be right that it is not shipped with OC. I only went to the apps page and activated files_mv.

Ok, given files_mv is crap. How do I move files/folders in the webinterface?

Ah, now i understand your concerns / post above. Yes, everything in the categories like "Tools" is pulled from

Moving files and folders is natively supported in ownCloud by "drag'n'drop" like described here:

Hm, this means I can only drag foles/folders only in parental folders, but not down into another parallel folder

A move from folder1/subfolder1/moveme into folder1/subfolder2/moveme would require a two-step operation:
step 1: Move upwards to folder1
step2: Move downwards into subfolder2.

Are there plans to show the folder hierarchy in a left pane as it is done for example in MS explorer? This would ease drag'n'drop...


you can check the issue tracker at if something like this is planned. I don't have any insights into the development process.

The same happens to me, but i don't have the files_mv enabled.
I'm running PHP-FPM with apcu cache enabled, so i think there's should be the problem.
Any clue?

Thanks in advance
