You used the word "archive". Does this mean you are keeping these files in MC, but just moving them to a less important/slower/cheaper drive?
I know exactly what you mean. RM&C is an amazing tool. But it kind of makes me nervous when moving big files or lots of medium sized files because of the lack of status. Because of this, when I do operations like this, I do the actual file moves externally from MC. Roughly, something like this:
1. Turn off auto import if it was on.
2. Use rsync or a similar utility to COPY the files in question to a different disk.
3. Bring up RM&C in UPDATE ONLY mode and change the drive and/or path to point to the new location for these files. I do one first to make sure I have it right. Then test. Then if it works, I update the rest of the files I have moved.
4. Externally remove the original files from the original drive. Again, I test with one file, verify that MC doesn't "need" that file (because it's been copied to a new location), and then do the rest.
It's kind of clumsy, especially if you have a big list of files. The Handheld Sync tool can be used too, and it has per file status indicators. This adds more complexity due to how Handheld Sync works and may not be worth it.
I would very much enjoy it if the JRiver team added a status bar, per file, to the RM&C tool. It's already a great tool. This would just make it that much closer to perfection.
