# Replace In Files not working for me using Extended Mode

• I am trying to replace a given line of text in many files with two lines of text

e.g. replace

#include “folder\somefile.h”;

with

#include “folder\somefile.h”;
#include “folder\otherfile.h”;

If I use extended mode it will find all occurrences just fine looking for

#include “folder\\somefile.h”;

But when I try to perform the Replace In Files action using this for the replace with

#include “folder\\somefile.h”;\n#include “folder\\otherfile.h”;

It fails just ends up doing nothing with

Replace in Files: 0 occurrences were replaced.

• Turns out that this was because the files were read-only. I was counting on the Perforce Plugin to automatically check them out but I guess that is not going to work. I will have to manually checkout everything and then perform the replacement.
