@webforpcnet seen similar issues before, also with other tools. Thing is accessing network drives (and even external plugged drives) triggers security and caching tools such as anti-virus, status utilities such as TortoiseGit, etc.
A separate check needs to be done using another crawler, such as a simple script dumping the file contents. Paste something like the following in cmd.exe:
@echo off rem Position in the target base directory pushd \\NAS\shared\code\ rem Iterate through all files in the subtree, assume all files, "*.*" for /R %i in (*.*) do ( echo Dumping '%i' rem Force reading file contents (but don't output them!), same as Notepad++ would type "%i" >nul ) popd(I’m assuming the \ special character sequence got escaped in the report.)
If the speed is substantially better than Notepad++ then it might mean there’s a problem (this quick/dirty check cannot assess for any whitelisting or heuristics in the environment).
