Thanks a lot for your response.
I have another example for you
To understand why this is a problem, I better explain the real-world scenario.
I work in Broadcasting, and have done a lot of work with Media Asset Management systems. After cameras went from tape/disc to Solid State memory cards for storage, the ingest process has moved away from dedicated professional operators, to (basically) the assistents in the editorial staff. These guys are often not technically trained at all, and as you can imagine things often goes wrong.
Video productions rely on consistency to make the "machine" run smoothly. With regards to camera files, it´s always a good idea that they are placed in the correct folder. If they are not, the amount of emergency phone calls and emergency emails is unbelievable.
When you ALT + drag&drop a memory card onto disc, the copy/clone gets a Date Modified stamp = "the moment the process started". This is just fine if the memory card(s) gets copied on the same date as the recording.
The Life happens, and for some reason the assistant don´t copy the cards on the same date as the video shoot. He grabs a beer and forgets about it, or gets sick, or his mother gets sick, or ........
Well ... Back in Hazel .... we are doing something like this ...
We need to copy the memory card clone to another disc for backup.
We need a folder structure on the backup disc that´s like: Disc Name/Projects/Project Name/Memory Card Backup/Date of Recording/
Because the editorial assistent has copied the card on a date on a date different from the actual video shoot, the name of the "Date of Recording" folder will be "wrong". (not "recording" date, but "when the assistant actually got to do it" date.
Why is this a real problem ? Because Editorial is creating written reports "on location", specifying (among other things) the name of the memory card been used in the camera, and of course the date. These reports are later issued to all members of the production crew, including Assistent video editors, Video editors, VFX, Color correction, Graphics department, Audio post production, Video Post producers ... and so on
When these written reports don´t match with whats on the disc, all hell breaks loose ....

But .... There is a way to solve this, and the solution is found a couple of folder levels down on the memory card clone.
The actual video files on the memory card still retains the original creation date from the video shoot.
Remember the file path : Disc Name/Projects/Project Name/Memory Card Backup/Date of Recording/ ?
I need a way to make the name of the "Date of Recording" = "Date Created on the actual media files" buried folders down on the media card itself.
basically it boils down do ...
* Been able to get hold of a file attribute
* Hold on to it for some time
* Re-use it later.
I have limited experience with Hazel.
I have not found a way to extract the "Date Created" of a file buried inside sub-folders in a folder, and use that information to create a subfolder with the "Date Created name" inside another folder somewhere.
Maybe there is a way to achieve this. In that case ... please let me know.
Kind regards, Nils M Alexandersen
