Hi. I have a strange question ! When you want to download eclipse, you choose a format that is compatible with your system, windows, linux, solaris, mac os x (zip, gzip .....). In the essense, do these versions deffer ? I mean, does windows's version of eclipse (for example) has files, dirs and extra jars that are defferent than linux's version of eclipse ? Can I copy the extracted zip file of eclipse on windows to linux's drive and runs normally on Linux ?? Any ideas ??
