## Feature request

Version 4.0.0

**Is your feature request related to a problem? Please describe.**
Desktop client synced a file but it is not obvious where. Often one wants to immediately use the synced file. Hovering over a synced file shows the relative location of file but the UI probably "knows" where the file was synced to.

**Describe the solution you'd like**
The ui alows a right click menu with one entry "Open file location (or folder)" along with perhaps, "Open with default editor/viewer"

**Describe alternatives you've considered**
It is possible to memorize the relative path, manually open a file manager, navigate to the nextcloud sync folder and than to the memorized location.

**Additional context**
