Share vs explorer

[saikrishnatavva]

I saw two more terms which I got a little confusion.
Those are:
1.alfresco share
2. alfresco explorer.
As per my knowledge, I came to know that share & explorer both are different UI. we can't implement the custom behaviour to the explorer. we have to implement a share (UI) for our custom behaviour. Am I right ?

>if the above point is true . How can i make my documents to be view in the explorer.
> As per my knowledge in CMIS, I can't create a document & view it those in the explorer. By using the CMIS we have to build a separate "share" archetype, write our custom behaviour in it by using JAVA & the documents which i create is only viewable in the share not in the explorer.
>In order to understand full functionality of alfresco, I am referring the document which is in the below url to implement the custom behaviour.

But I am getting Errors while installing. I have posted detailed about my error as a separate topic in this url: https://forums.alfresco.com/forum/developer-discussions/development-environment/unable-create-custom.... can you help me to find the error.

No you are not right.    A custom behavior works regardless of any user interface.

> can i set permissions at file level(some users shouldnt allowed to view the file). If possible can i set this permission level programatically.

Yes, Yes

> Does Alfresco Allows to store huge files like BLOB, filetyope, extentions etc…

Yes
