This post is designed to help you who find the Office 2007 hangs when opening network file. Many of the complaints mentioned include:
When we open the excel shortcut, the program is run normally but it takes longer to open a document file. Some people try to choose the Excel - > Open - > and browse the appropriate documents to immediately open document they want.
Actually, the problem caused by Office File Validation (OFV) which checks the file is trustworthy before it opens the file. Of course, this check process reduces your performance because of the network traffic when reading in the parts of the workbook.
