In the daily work, the more important files, we will lock it, but some documents are to be open to others to see, but do not want others to change it. So at this time we need to set the WORD document so that others can only read but cannot modify and copy. If you want to set it up, let's take a look at it with Xiaobian.
First, open a WORD document on the win7 64-bit pure desktop, and then click on the menu bar for review in its interface. Then click on “Protect Document” in the upper right corner of its interface, click on Restrict Format and Edit.
Second, in the system limit format and edit drop-down menu, select “ fill out the form & rdquo;. Other options can't restrict user copying, so be sure to choose this option here. Click on the bottom of the "start mandatory protection”.
Third, then in the dialog that pops up, enter the password. Then click the OK button.
Fourth, at this time we return to the win7 system text interface, just select a paragraph of text, found that its cursor can only start at the top of the document, will not move with it. This means that the selected document cannot be made in the document, ie it cannot be moved and copied.
