Behavior of dirdate -dirfix

Recently an Expert introduced me to a utility called dirdate, which helps to correct time stamp errors.  When dirdate -dirfix is applied to a folder, the folder's creation date set to the oldest modified date of any file contained within.  The folder's modified date is set to the newest modified date of any file within.  My question is:  wouldn't it make sense to set the folder's creation date to the oldest creation date of a contained file, instead of the oldest modified date of a contained file?  If so, is there a method for accomplishing that?

Aloha David,

> wouldn't it make sense to set the folder's creation date to the oldest creation date of a contained file

That's exactly what DirDate does. Here's a verbatim quote from its readme file:

-DIRFIX   Set the folder create date to oldest file, modify date to newest file

Hi Joe:  Glad to hear from you.  Yes, it sets the create date to the oldest file.  But not to the "create date" of the oldest file.  Instead, it uses the "modify date" of the oldest file.  That is the reason for my question.

Ah, that's a bug in DirDate. I already reported it to the DataMystic folks...I have a direct pipe into a high-level person there. But you should report it, too, via their standard support mechanism, which is either sending an email to <support@datamystic.com> or filling out this form:
http://www.datamystic.com/support.html?application=DirDate

I've had great results in the past with very fast turn-around from them on fixing bugs...and even adding new features. But keep in mind that they're in the Melbourne, Australia time zone. Regards, Joe

Simon, from DataMystic, says that the feature I am requesting was not the original intent, but it would be an improvement.  He plans to add it to a new release, expected to be available by early January.

That's excellent news! I received the same "next release" comment, and it wasn't a "maybe"...it was a "we will". But I didn't get a time frame, so great to know that it's early next month, just a few weeks away! Thanks for the update. Regards, Joe

Hi David,
Wanted to let you know that I just got an email from Simon at DataMystic that says, "Early Jan. Let me know if I can help further." So at least we're both getting the same story. :)   Aloha, Joe

Interesting how nimble a small company can be. Imagine how long it would take for a large software company to respond to a request like this, whether bug or feature.

Hi David,
Just a quick note to let you know of a bug in DirDate's context menu [DirDate fix folder dates]. The bug wasn't introduced in 6.1, but testing that new release brought it to my attention (the bug has probably been around for a while). When you right-click on a folder in Windows Explorer or Total Commander (or any file manager) and select [DirDate fix folder dates], the registry entry is sending this command:

"C:\Program Files\DataMystic\DirDate\DirDate.exe" -r -DIRFIX "%1"

The problem is that Windows sends the folder name in the %1 variable without a backslash. This does not work in DirDate with the -DIRFIX option, which requires a backslash on the folder name. I reported it to Simon (along with two suggestions on how to fix it) and he wrote back, "will fix for next release." I don't know which suggestion he'll implement – one is better than the other (more general), but harder to do.

In the meantime, if you'd like to fix it on your own (with the simple, less general fix) and are comfortable with changing the registry, find this key:

HKEY_CLASSES_ROOT\Directory\shell\DirDate\command

and change its value to:

"C:\Program Files\DataMystic\DirDate\DirDate.exe" -r -DIRFIX "%1\"

In other words, simply add the missing backslash after %1. I did this and it now works fine. This bug is probably not affecting you, since your usage of DirDate -DIRFIX is from the command line, so you no doubt have included the backslash (or it wouldn't be working for you), but I figured I'd let you know, anyway. Regards, Joe
