error with brute-force

[atom]

It is clear now. This is not a hashcat bug. The error message is a bit misleading, but technically correct. What happens is that the shell (in your case cmd.exe) tries to match all files because the mask you used, ???????, is interpreted by the shell before being passed to hashcat. In your case, it matched a folder named "bridges" and then passed that string as a parameter to hashcat.

At that point in the command line, hashcat expected a .hc22000 file, but "bridges" is a folder. Therefore, it reported that this folder is an unsupported file type. So everything is working as intended.
