Copying docs from one project to another project in ZOHO

Copying docs from one project to another project in ZOHO

I would like to know if there is a central place in ZOHO where we can store the docs and which can be taken by other projects. I tried copying it in 1 project and pasting in other project but it did not work. I do not want to download it to desktop, as I am losing few features in the document. Also trash seems to be separate for each project if i want to copy it from there.
