Changed up my search query and found this thread over on the NI forums that explains the problem. Looks like it's indeed the 32-bit limitations.

I'm trying to automate the backup of a large number of TDMS files. I've got them sorted out by year and month, but there's usually about 20GB per month (uncompressed). I'm using the OpenG Zip library to do the compression and my first few attempts at a whole folder threw an "error 7" at 2.00 GB. It also leaves the archive in a state that is unusable by Windows. Not a lot of useful info in the error messages from this library: Took me a few hours to sort out that if you include an archive name, you can't use the "create new" option. =/ Is this a limitation in the core zip file utility, possibly because it's 32-bit? Has anyone successfully compressed a similar size chunk of files? Thanks in advance! LabVIEW 2014 sp1 32-bit OpenG Zlib 1.2.3 Win7 Pro 64-bit
