You should be able to see .fcpcache and fcpcache.tmp right inside the Library package. Just CTRL-click, choose Show Package Contents, and they should be there among the other files and folders in the Library. Since they’re hidden files (they’re actually Aliases), they’ll look greyed out, but you should see them as long as you’ve successfully unhidden the hidden files.

The exact path depends on where your Library is, but here’s an example with a Library (FCPX_Movies.fcpbundle) in my Movies folder:

/Users/DM/Movies/FCPX_Movies.fcpbundle/.fcpcache

And this is a screenshot of what I’m seeing (just using a generic Library):

It seems like fcpcache.tmp only appears when there’s a conflict with the cache (or at least with the alias), which I think is what’s happening when a Library is on a Terrablock. So I think if things are working normally (i.e., you can render and export), then you probably will not see .fcpcache.tmp.

And yes, 10.1.2 allows you to set the cache anywhere you want, but it seems like the hidden .fcpchache alias is always in the Library package. It’s interesting to note that when the Library was on the Terrablock and I tried to change the cache location, I got an error message that was something like “Can’t write because .fcpcache already exists…” That’s when I started looking for that particular file.

Anyway, hope that helps.

After upgrading FCP X to 10.1.2, I had the same problem with not being able to render or export when the Library was on our Terrablock. Moving the Library to a local drive also didn’t work initially, but I believe I’ve figured out how to fix that.

It seems there are 1 or 2 hidden files in every FCP Library that can cause problems if it is (or was) on a Terrablock volume: .fcpcache and potentially .fcpcache.tmp. So, after moving the Library to a local drive, I deleted those files, then opened the Library in FCP X and was able to render and export again.

There shouldn’t be a problem with keeping all the media (and now even render files) on the Terrablock; it’s just the Library itself that needs to be elsewhere till this bug gets fixed.

By the way, if you don’t know how to show hidden files, just enter the following into Terminal (and be careful not to delete anything important):
defaults write com.apple.finder AppleShowAllFiles -bool TRUE
killall Finder

To hide the files again, just replace TRUE with FALSE.

I’m running:
OSX 10.9.4
FCP X 10.1.2
Facilis Terrablock Manager 6.0.1
