you can start Zcash as “zcashd -datadir=” and then the location for the files!

Thanks for this solution.

Is it possible to somehow specify this option in the configuration files to make it the default?

that I have not tried! I’ve always seen it passed in on the command line, and was wondering the same thing myself last night while working on an app that uses datadir=

Ah, it seems like `-datadir=` is the exception for the zcash.conf. Bitcoin has the same thing… only bitcoin-qt (which calls bitcoind) can save a configuration to start the client with the modified directory location each time.

Storing `datadir` in `zcash.conf` is paradoxical since `datadir` is the directory in which `zcash.conf` is stored. 🙃

cp -rp ~/.zcash/\* /new\_dir rm -rf ~/.zcash  
$ ln -s /new\_dir ~/.zcash

$ chown -h your\_user:your\_group ~/.zcash
