Doing clean install after mess up, put my image, video, music, text files to external hard drive (not time machine). I was checking them in Windows computer and found many files having copies that all started with " ._ "
None of them could be opened. I checked Internet and seems Mac just makes copies like that for system.
But no where can I find answer:
1) could these files carry anything malicious for Mac?
2) Are they files that could run a code? Executable files?
3) Or are they same as any image file? As in risk of ._ files having anything bad in them being as low as risk of image/video/music/text files having anything bad in them?
4) If ._ file is copy of something actually malicious, will ._ also be malicious?
