Using the standard client, Bitcoin-Qt, v0.8.1: (win10x64)
I would like to move the blockchain data from its default location to a different location (maybe even an external disk or NAS drive). What should I do to make this working while moving that data?

This step-by-step how-to assumes you are using Windows 7 and installed Bitcoin-Qt to the default directory.
-datadir="the new data directory"2This moves the wallet too, which I think isn't what the asker wanted. – Nick ODell – 2013-07-30T21:18:57.963
I do not want to move wallet file. Just chain, because it is growing too big you know. – Comodore – 2013-11-18T11:25:44.720
Anybody know how to do this in linux ubuntu? Im going to run out of storage room before the blockchain synchronises. Its used 12 gig plus and still have 24 weeks to complete and I only have 2 gig left on my laptops hard drive and would like to store the blockchain on a removeable passport hard drive. – user3088693 – 2014-02-21T10:48:11.593

Except for the most recent file (which is being written to with each new incoming block), I believe you shouldn't have a problem in moving the other files with the wallet still open - aren't they read only?
Moving the last one, though, would probably require you to close the wallet even if just temporarily.
1What operatng system? Symlinks can help. – Stephen Gornick – 2013-10-02T00:43:39.047
Asking about how to change the default storage location has been posted many, many times. The future canonical question is probably Bitcoin-Qt setup: Change block-chain file location, settings? documentation?. Possible duplicate of Bitcoin-Qt setup: Change block-chain file location, settings? documentation?.
