FindFirstFile Error #15

Closed comanche closed 3 years ago

comanche commented 3 years ago

Tried running this command:

DirHash.exe G:/ blake3 -t E:\dirhash.blake3 -overwrite -sum -threads -nologo -progress -nowait -exclude

Go this error: FindFirstFile failed on "G:\System Volume Information" with error 0x00000005.

Wondering if there are handling issues in the System Volume Information folder.

"System Volume Information" is a special folder created by Windows and which cannot be accessed by users. The error code 0x00000005 means "Access Denied". So DirHash cannot access the content of this folder and that's why the operation is aborted.

You can tell DirHash to ignore this system folder by using -exclude switch. So the command becomes:

DirHash.exe G:/ blake3 -t E:\dirhash.blake3 -overwrite -sum -threads -nologo -progress -nowait -exclude "G:\System Volume Information"
