That wasn't exactly the answer I was hoping for but I guess I'll make do.
Is there any way to tell if something has been added to the cache? What is the default active cache file?
C:\Users\<user>\AppData\Roaming\TVRename\cache\Cache\Cache_Data\data_1 ?
If I see that file grow in size that means a change was made to the cache and I can send out a "TVRename.exe /save" to lock in the change to the library. Right? No? Is there any other way to do it?
Like I said, I run 24/7 and fully automated. If a torrent arrives in the middle of the night and gets put in one of the Search folders and gets processed into the cache, I may not be around to click on File > Save to protect it from possibly disappearing in a power outage. If all goes well my UPS batteries will be installed in the coming weekend and lessen the likelihood of that happening, but still...
There must be a good reason for you to want to store away any changes temporarily in a cache rather than just adding them directly to the various library and setting .XMLs but I can't figure it out.
