I use a lot my Finder (Mac) to go to the maps to look at the files.
A button “Show in finder” under the “pencil” or “the three dots” would be really nice.
There’s already an existing feature suggestion discussing such an option.
Keep in mind this is a far shot as it’ll only work if you’re accessing it from the machine running your PMS. Many clients might not even have access to the share where the media for PMS is hosted.
In anyway… I suggest you comment/vote in that existing thread in order to avoid distracting/dispersing votes.
I’ll therefore close this thread as a duplicate.
