Actual behaviour

  • folders (and its content) with special char ([ or ]) will not be synced

Expected behaviour

Steps to reproduce

  1. create folder (with any content) with special char at the beginning on your desktop; e.g.: [2019] Halleluja

@der-domi sounds like . It got fixed and will be released in the 2.11. You can verify with the 2.11 beta ( see post ownCloud 2.11 beta app for Android )



if the same can be reproduced on the demo instance then personally i would report such an issue to a bugtracker rather then to a user support forums. From what i know bugs in the android app could be reported at

But maybe the following in the upcoming release 2.11 of the android client might be related?

You are right! Next time I will do that. I also had this idea after I write the question. But than I already received Michaels answer.

Thanks to you both. I will test it asap. But I also think that the above mentioned issue will fix the bug.
