Solve Word Cannot Open This Document Invalid Characters Error

“I had edited few Word documents on my cousin’s laptop recently. After moving these documents to my desktop, as I try to open them, I keep receiving error message like “Word cannot open this document: Invalid Characters”. I verified that there are no invalid characters in filename or with its path. I am worried what caused this error with my Word documents and how to resolve this situation.”

Word documents may display error message like “Word cannot open this document. The document might be in use, the document might not be a valid Word document, or the file name might contain invalid characters (for example, \ /).” This error might usually occur to Word documents that are saved on shared network. Users from all computers that are connected to specified network can open / edit such Word documents if admin has not set any access permissions for those documents. Thus, since the file will be edited on different computers, chances of file corruption are more that results to above mentioned error.

Apart from sharing Word documents over network, few other factors due to which Word document may show invalid characters error message are presence of unknown symbols in the Word filename and intrusion of harmful viruses during Word file transfer over network. However, when Word cannot open any file due to invalid characters error, one can save this document with different name in new location on system hard drive, so that document can be accessed without trouble.
