Identify ENCRYPTED compressed files at the command line
- by viking
I have directories with hundreds of RAR files. Currently I use Powershell 2.0 with a script that utilizes WinRAR's RAR utility to decompress the files. The issue is that a small number of the files end up being encrypted, which pauses the script and requires interaction. Is there any way to do one of the following:
Identify the encrypted files before trying to decompress
Entirely ignore the encrypted files
Automate an incorrect (or correct) password that will attempt to open the file, but just skip it if incorrect.
NOTE: Some of the compressed files encrypt just file contents, whereas others encrypt file name and file contents.
Relevent Code:
$files = Get-ChildItem
foreach($file in $files)
{
if($file.Attributes -eq "Archive")
{
$folder = $file.basename
rar x $file $folder\ -y
}
}
