I think it's because your USB drive has a file system that does not store executable bit permissions, and is being mounted so that all files show up as executable.

A mount option like showexec for fat filesystems is supposed to do this: If set, the execute permission bits of the file will be allowed only if the extension part of the name is .EXE, .COM, or .BAT. Not set by default.

You can check how your drive is mounted with the mount command, and man mount has lots of info on the different options.

  • Interesting. Part of the output of `mount` for the relevant drive is `type vfat (rw,noexec,nodev,uid=1000,gid=1000,umask=000)` – cfye14 Jun 29 '15 at 05:50
  • I tried creating a test fat filesystem (FYI with `head -c 1M > tfile` then `losetup` & `mkfs.vfat` & `mount`) and using no mount options & remounting with your options, all files display as green with the executable bit set, `ls -l` shows `-rwxr-xr-x`. Adding the `showexec` option with `mount -o remount,showexec` didn't change it, but umount-ing and then mounting with `showexec` DID work, and plain text files were NOT green/executable. `mv`'ing a 5 byte text file to a name ending in `.exe` did not immediately change it to green, but umount & then mounting again DID show only the .exe green – Xen2050 Jul 01 '15 at 10:39
