Nextcloud Portable stores log and cache in AppData

[NewKidOnTheBlock]

Nextcloud Portable likes to store a log in the following folder:
%APPDATA%\Nextcloud
The file is called:
db_sync.log
This log is re-created every time Nextcloud Portable has been run.

While Nextcloud Portable is actively running, it also creates a temporary cache folder here:
%LOCALAPPDATA%\Nextcloud\cache\qmlcache
It contains 84 .qmlc cache files.
When Nextcloud Portable has been shut down, the cache folder disappears.

IMHO both of these folders and files should be confined to the Nextcloud Portable directory, especially the log file as it contains detailed information about the names, locations and sizes of all files that have been synced during the last Nextcloud Portable session.

Setup:
Nextcloud Portable 3.14.3-22 win64
Windows10 64bit
