How to display unblock files

[dmocha]

Refers to:
https://www.tenforums.com/tutorials/5357-unblock-file-windows-10-a.html

I wonder if it is possible to display (distinguish) blocked files in TC?
Any plugin? Another way?

And the second question is whether it is possible to lock the file again?

[Dalai]

This flag is saved in NTFS Alternate Data Streams (ADS). Any plugin or program which is able to show such streams can be used for this. Starting in version 10.0 TC itself is also able to display from this specific ADS in Ctrl+L dialog and in custom columns.

Note that ADS can contain arbitrary data. This flag is just an ADS with a specific content.

Theoretically it's possible to add the ADS to a file to block it again. The quesion is why would you want to do that? Windows doesn't prevent executing a file with this flag, it just adds another confirmation layer (one that doesn't add any security IMO).

Especially look for ZoneId !=0 property of internal (tc) wdx plugin.

ADS = Alternate Data Streams

For example, a PowerShell script [it will display all the locked files (if any) within the current directory]:

displayLockedFiles.ps1

Code: Select all

function ifLocked ($i) {
try {
[IO.File]::OpenWrite($i).Close();$false} catch {$true}
}

$lockedFiles = @()

Get-ChildItem -file -force -recurse | foreach {
$i = $_.FullName
if ((ifLocked $i) -eq $true) {$lockedFiles += $i}
}

if ($lockedFiles) {
Write-Host -f Green 'Locked files:'
$lockedFiles|foreach {Write-Host -f Yellow $_}
}

pause

Edit:
I didn't follow OP's link back then, and now I did.
Now I see the link deals (so OP's question does as well) with the blocked files that are blocked by Windows Security (malware, viruses, etc. protection).
Of course, my above message is about something else than that.

I was just wondering if it is possible and if so, how.

Thank you all for your replies.
