When connecting to my Synology NAS via webDAV certain files (*.java, *.class, other?) are invisible. Some other are visible. Folders all ok.
Maybe this is caused by very deep nesting (path ist Z:\htl\dat\script\0pgmJava\20172018\src\donald\src\donald)?
It worked in prior versions maybe 3 months ago but stopped working in December 2018 (?) when still using NetDrive2. I therefore updated to NetDrive3 without solving the problem.
