I know this is a rather noob question, but surprisingly this hasn't been asked on SO before.
I recently launched my first application on Google Play, and had stored my Android Keystore on a flash drive as advised in The Busy Coder's Guide to Android Development. I am the only developer and so don't have problems related to sharing of the keystore with my peers.
But now I want to format the flash drive which, though not necessary, would certainly be better as it has some errors in it. So my question, can I actually back up the .jks file to some other location on my machine and still continue updating my app through it?
The .jks file can be copied, e-mailed, compressed and uncompressed, et cetera and still be used like the original.
