If the intention is to copy the BIN file from one switch to another, I'd strongly recommend you don't do it.  The reason behind it is, if one doesn't know what he is doing, the file being copied might get corrupted and the switch will boot into ROMmon.

I don't recall having a problem doing that on the 3750 series, and if you have a mixed (StackWise and StackWisePlus) stacked, I think it's required to perform an upgrade.

I have no experience with the later 3650, 3850 or 2960 stacks, so I cannot comment on them.

I know this is an old post, however there's no issue copying the binary files from one flash to the other flashes:

Do the verify option to confirm there's no corruption, reducing the risk of being stuck in ROMMON.
