i) To browse/manipulate/transfer/etc. PC & Mac files/folders on an Android device:
This is the best method so far (Jan 2014):
Computer side:
1) Share the hell out of a
folder in Windows preferably
with "Everyone" option. You can, if you like, make it a mega-data folder with sub-folders for mp3, movies, ebooks, etc. "Everyone" share option is the most full-proof if facing connection handshakes problems & is easier in operation later too but less secure, which is no problem if at home. Easy-peasy, lemon squeezy, also Mac guide:

Any problems just google for more guides: share Windows folder
Android device side (even easier):
2) Install "Total Commander" file manager on Android device:
https/play.google.com/store/apps/details?id=com.ghisler.android.TotalCommander
3) Install LAN plugin for Total Commander:
https/play.google.com/store/apps/details?id=com.ghisler.tcplugins.LAN
4) In Total Commander root list of folders choose:
LAN (Windows shares)
a) Click
+ < New server >
b) Enter any name (I use the IP number, as they change)
c) Just
Enter the IP number of PC at top, leave the rest empty/as is.
DONE! Less than 1 minute for the Android part.
At Total Commander start, click LAN (Windows shares), click on what you just named & setup: you're in the PC!
As IP numbers change, use Fing to see IP number of network devices:

Instead of making a new one, you can change the IP number of your creation if it changes in future:
Long-Press your created connection: Properties: Change
Example: 192.168.1.4 to 192.168.1.5 if that is your PC now as shown by Fing. Takes 10 seconds!
I used Total Commander since beta. It's like old programmers dual-pane faves, NC etc. Plus IMHO & many other programmers it's the best file manager on Android & is on all my devices' dockbars. Finally, it's free & ad-free, the guy who makes it never asks for donations or rating or other messages. Also the FTP plugin setup is similarly easy:
https/play.google.com/store/apps/details?id=com.ghisler.tcplugins.FTP
I use other dual pane file managers on Windows & Mac as don't like Total Commander interface there or the fact it's not free there, but on Android apart from seeing Windows shared folder aspect, it's the best file manager for copying/moving/deleting multiple files. Plus Android sysfiles (access, attributes, installs etc.) are taken care of easier than any other app. Newbies should not mess with "File System root" files & folders.
Click on a file(s) icon to select (not filename), bottom icons (copy move delete etc plus multi-select) to send to next pane. Dual pane in landscape mode. Clicking filenames launches it. Long-Press gives more options. Does zipping & unzipping too. Make new folder is in menu command.

ii) To browse/manipulate/transfer/etc. Android device's files/folders on PC & Mac:
Of course you can simply connect your Android device's micro-USB cable to PC & Mac, given correct USB drivers are installed on the computer.
For WiFi, slightly tricky, I:
1) I'm not keen on Samba server as it hogs too much. I run a
FTP Server. I run mine from app:
Servers Ultimate (
Pro version) on Android, it also has SMB & other servers. Android FTP servers are not so hot but this one works best IMHO.
2) I run
Webdrive (paid version) on Windows 7 (maps a FTP Server to a drive). Or, for less Explorer like functionality, could use a good normal
FTP client like
WinSCP or FileZilla which are free and do everything file/folder wise.
