Changing created, modified, accessed times of files

Question

How can I change (preferably in batches) creation, last-modified and last-access times of files?

Answer 1

FileDate Changer will do this.

You can simply drag and drop into the Filename box and apply changes in batches.

Tested up to Windows 7, it is free and only a couple of KB.

Answer 2

In PowerShell, something like:

$date = Get-Date "2010-01-31 10:11:12"
Get-ChildItem *.foo | Foreach-Item {
    $_.LastWriteTime = $date
    $_.LastAccessTime = $date
}

Answer 3

Take Command Console LE (TCC LE), a free souped-up replacement for the command prompt, has a touch command that can change the creation, last modification and last access times and dates for files. It can of course run batch files.

The parameters to use are /D (for date) and /T (for time):

/D

On an LFN drive, you can specify which of the date fields should be set by appending a, c, or w to the /D option:

a Last access date 
c Creation date  
w Last modification (write) date 

/T

On an LFN drive, you can specify which of the time fields should be set by appending a, c, or w to the /T option:

a Last access time (on VFAT volumes access time is always midnight). 
c Creation time  
w Last modification (write) time
