a question should ask Microsoft

[dsun01]

Dear support, 

this is not a joke, I should ask this question to Microsoft, but don't know how.  

while I am working on a Quartus project, there a lot of .v files, and I want find a variable in all the files, so I use win10 file explorer, in this case,  a variable "avmm_addr", in a file called fx3_reg_ctrl_hw.v,  but win10 told me there are no file contains this string. I feel very strange, and did a little explore, I found that if I create a new file, pure_testfile.txt, and copy paste all the content in the called fx3_reg_ctrl_hw.v. and did a search again, this time win10 find the string in the called fx3_reg_ctrl_hw.v. I attached both files. 

have this happened to anyone before? may be after many times zip and unzip, the text encoding already been changed to a strange one. but quartus editor, and win10 notepad didn't complain or warn anything wrong. 

thank you for helping. 

David

Perhaps Windows is not searching .v files for text the way it would a .txt or .docx file?
