Tech question - 1000's of folders ???

Just a quick tech question.
Why does LR create 1000's of folders to hold the previews. One catalog has over 1600 folders, most of them empty. Between all my catalogs I have over 10,000 folders!
That really screws up searches on the hard drive, the backup takes a heck of a lot longer, etc. To say nothing about consuming large amounts of disk space just due to file/sector allocation.
There must be a reason for this... but what? After all, the previews don't even use the original file name, so it can't be for file name conflict resolution.

>Say what they may, I'm convinced that LR in all of it's V1.0 versions is a knee-jerk rushed reaction to the utterly sudden appearance of Apple's Aperture,
Simply untrue...Lightroom (AKA Shadowland) was started Dec 2002 (in my studio I might addthat's how I know for an absolute fact when it started) and Aperture was started in the Spring of 2003. I know that because the Apple marketing guy writing the marketing spec for what would end up being released as Aperture interviewed me (the only contact I had with Apple with regards to Aperture).
So, you can "think" what you want as long as you want, but if you want to be correct, you really should change what you think. The full story (minus some proprietary stuff and some other stuff to keep from embarrassing certain peoplesome of who are gone from Adobe) was written in
THE SHADOWLAND/LIGHTROOM DEVELOPMENT STORY.
>This is why I say that LR doesn't feel like a 'professionally' designed program... the front looks great, but you look behind the makeup and it looks really amateur.
Uh huh. . .and how many software product development project have you been on? Care to post your creds that would make your opinion relevant?
On the Mac, the entire Lightroom Database Previews.lrdata is a "Package" which contains the subfolders and the preview.noindex files. On Windows, there isn't a similar construct as a "Package" so the previews are tucked into subfolders inside the enclosing folder named Lightroom Previews.lrdata So, what's your problem with subfolder containing the preview.noindex files? Is it because YOU think it's messy? Why?
In my main Lightroom catalog (which has about 78,000 images in it) the Lightroom Database Previews.lrdata package is about 36 gigs...these are generated preview files that Lightroom uses to avoid having to re-render each file you look at. Where should all this data be saved? Why should you care, in the least HOW it's organized? It's organized in a manner that Lightroom needs to be able to access it.
If you want to suggest an alternative organizational structure, go right ahead. Suggest...but, without an alternative organizational structure, what would YOU suggest the Lightroom engineers do? What would YOU do?

Newbie Question on renaming drives/folders

I have found how to rename folders but the drive for Windows shown on my desktop in OSX says Untitled and it bugs me. Can I rename it to reflect Windows?

Well I put my drive back to it's orignal state. The Windows disk I received was defective, I tried another one I had not remembering that each key is tied to it's disk....So when I went to enter the new product key I received a invalid key error. I tried the usual ways to get around it and still would not work. I even called MS (BIG BIG BIG mistake) and went through 6 people to finally just tell them I wanted to return it and get my money back. This Macbook is my first Mac and I must say the experiance with MS tech support may push me to by another MAC sooner than I expected. LOL This thing will have a learning curve no doubt but at this point I love it...if I could only figure out the little things (shortcuts,copy,paste,multiple select items; like ctrl or shift and select in Windows) I would be even happier. I appreciate the quick replies and help on my question also, I hope to be able to help out someday as well.

Question regarding iphoto and folders

I am a Mac newbie (9 months) and quite happy expect i freeze all the time after i installed lion, but that is for a different thread.;)
I had all of my pictures on an external hard drive. I had them organized in folders by year (also had a Year/edited for family photos we changed) and then by date/event...ie, 2011 04-05 Easter Dinner at Dad's.
When I got my macbook pro, I hooked up the hard drive and iphoto took care of importing all the pictures. (i have upgraded to iphoto 11). At first, I LOVED it. Putting face names in the pictures, etc, but after a while i got tired of having to reorganize them to find pictures the way i used to. I have over 15,000 pictures and renaming (even with the batch option) and moving them, and fixing dates, etc was becoming overwhelming. I found myself longing for my very simple folder organization. So i went to look for the folders, eventually found them and found out there were folders for originals, modified, thumbnails, etc. and when i went in my originals, they weren't in folders I had originally had on my external drive.
My wife, who is our picture editor, preffers photoshop and i have a windows laptop that i want to use for nothing other than pictures.
So......my question is:
How can i best take my photo's and put them back on a hard drive and then transfer them to the other laptop? Is there anyway to recover my old file system (deleted off the hard drive, except for an old backup but i have added thousands of pictures and have no way of telling which ones are in iphoto are old or new). I am fearful that if I just copy iphoto to the hard drive that the windows laptop will not read them, or that it will still show up with all of the different folders (original, modified, thumbs, etc)
And/or, is there a program to manage pictures for my macbook pro that will keep photos in folders more similarly to how i did before, so it will be easy to move pics from one laptop to the other.
Thanks!!!!

1. You know that iPhoto can do all this.
2. You can sort by Date -> View Menu -> Sort Photos.
3. You can search by date -> Click on the Search icon and select calendar. Then you can find all the pics from any day, month or year
4. You can search by date using Smart Albums too.
5. You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.
6. No there is no way to export back to your previous system. It's gone. You could have easily imported while mirroring that system, but it's too late for that now.
7. To get Photos out of iPhoto: File -> Export. Apps like iPhoto2Disk or PhotoShare will help you export to a Folder tree matching your Events.
8. iPhoto can run a Referenced Library (where you have your own folder system) but I don't recommend it - especially for people unfamiliar with iPhoto and Macs. It also adds no extra functionality at all. It's just dumb storage.

Question mark in all folders

I have a grey question mark in the toolbar of all my folders, even the empty ones, since recently?
At least never noticed it before.
Clicking on it results in the message "The item can't be found" or something similar in dutch.
What item can't be found? (in an empty folder)
I do have a problem with a file created by FileMaker Pro which in an AppleScript can't be found, although the file is there and the file path is correct.
A similar question was posted here recently, but the answer was not very satisfactory.
Anyone with an explanation?

Help! Has anyone ever seen a strange question mark in their folders?

please help, for some reason there is a strange question mark on the top bar of every folder that i open, to the left of the search box. It's quite large and slightly darker than the folder window color around the edge, and when I click it it pops up a new window that says item cannot be found. It has never been there before, what is it and where did it come from, is this a virus? S.O.S.
powerbook G4 17" Mac OS X (10.4.6)

Control-click on it and choose Remove Item from the menu which appears. The Finder toolbar allows files and folders to be dropped into it; when the Finder can't find one of these, it displays the question mark icon. It is not a virus.

A simple question: Using the user-folders differently

Hello,
I'm still getting started with my mac, that's why I have a pretty basic question:
There are these user-folders on every mac: Documents, Music, Pictures etc.
But since I sort my photos and videos by date, I often have pictures and videos in one single folder and don't want to seperate them in these user-folders pictures and movies.
That's why I'd like to create a new folder next to Documents, Music... called "Photo_Video" (or something like that) where I can put all my photos and videos in.
So, my first (stupid) question: Is it ok to create a new folder in /Users/NAME/_____ ? I'm asking this because the existing folders seem to be kind of special (system folders?). Sorry about this, but I want to get everything right.
My second question: Is there a downside of NOT using "Movies" and "Pictures" for my media? I've heard somewhere that these folders are in some way protected against external usage.
Thank you!

Yes, you can create folders inside your Home. The folders there are not terribly special, but the Finder does treat them as such by putting that badge on the folders.
If you have multiple users and want to keep the folders private, you'll need to change the user permissions on the folders you create. When you create a new folder, it inherits the permissions of the enclosing folder. Your Home is set to allow other users to see directly inside so that they can see your Public folder and so the Web server can see into the Sites folder. Because of that, the new folder you create will allow others to see inside of it.
To change the permissions, select the new Folder and Get Info on it. The info window will open and the permissions are at the bottom. The list of permissions will have you as the owner and you will have read/write access. It will also have a group (I think Staff), and Everyone. Select any Groups (icon with two silhouettes) and delete them (- button). For Everyone, set it to No Access. If you are the only user and you don't share out folders over the network, then it isn't likely necessary to change the permissions.
I can't think of a downside of using other folders. The potential downside of not using iPhoto is you won't have the media browser to select photos from. But, that's not a really big deal if you can easily identify your photos in the file structure.

DLTS System (Trio-tech TC 1000 Temperature controller)

Hi I was trying to make DLTS(Deep Level Transient Spectroscopy) system using Agilent 4284A LCR Meter and Trio-tech TC1000 Temperature controller.
I'm done with LCR Meter but I don't know how to start Temperature controller.
There was labview driver for LCR Meter so I just modified exiting VI.
However there is no example for controlling Temperature controller by Labview.
Please help me if you can.
Thanks for reading this
Message Edited by daniel2852 on 02-13-2006 07:44 PM

Hi Daniel,
If you know the command set of your instrument, you can try communication using the VISA API. You probably have NI-VISA installed already since it is required for most of the instrument drivers on our web page. If you do not have it, you will need to download it from here. Is your temperature controller a GPIB Instrument? If so, try using the example I have attached below that uses the basic VISA functionality to write a command to the instrument and read back the response. You will need LabVIEW 7.0 or higher to run it. Just put in your gpib device resource name and a known command into the VISA Write and set it to read an expected number of bytes. You should be able to read command responses directly from the instrument. If this works, you can try to build your own driver around this example. You can also try using the Instrument I/O Assistant Express VI which often allows for instrument communication without instrument drivers. This can be found on the Express palette on the block diagram in LabVIEW. I also suggest going to www.ni.com/idnet and selecting "Request Instrument Drivers" to put in a request to our driver development team. These are considered when developing new drivers for future releases.
I hope this works for you, but if you have any questions, please let me know!

My MacBook has question marks on all folders and won't run ANY program. Help!

A week ago I was editing some photographs in Photoshop CS 5 extended. My computer has been running slow for a while so I thought that I would finish these files and then clear it of some photos since I know I've recently uploaded several gbs onto it.
The next day it was frozen. I had to shut it down and restart. It came on and now every folder has a question mark on it and none of the programs will open. They just bounce up and down and then the menu bar says Application not responding.
I have no idea what I need to do. I was going to update to Lion but I'm unsure if that's what I should do or if it needs some TLC from the apple store.
Help?

A professional will image your drive and attempt a bit by bit file recovery method directly from the drive itself.
You see when you delete something, it's not quite erased yet, but the space the file took is available to be overwritten, so it's only a matter of time before that occurs and the file is really gone.
So they will recover what they can, and then restore your machine and it's software and return the recovered files.
The TimeMachine is certainly going to assist, good thing you got it.
The trick is to hire someone and quit using the computer until they rescue you, show you in person how to rescue yourself .
Good Luck

Follow up to 'really messed up' tech question

As mentioned in my previous post below, I accidentally deleted all my iweb pages somehow after attempting to add google adsense to my site. While trying this my first attempt to add them to my site 'published to a folder' was a success, while trying to add them to my site 'published to the web' did not work.
I tried replacing my published website with the site that was published to the folder (and had the ads showing), but I still see the code and not the ads on the web. Question: Can the ads look correct in the published folder and yet still not show correctly on the web? I do see that the code is partially hidden, is that why when trying to publish it to the web it doesn't turn into ads? But it doesn't interfere with it being published to a folder?
Also when copied code is pasted into a 'shape' and you can see that the code is partially hidden, does it make a difference? Can or should the code be manipulated to fit inside the shape?
Thanks for any insight.

Karen ~ Are you aware that iWeb '08 makes it easy to add +Google AdSense+ ads to your site? ...see this video tutorial:
http://www.apple.com/ilife/tutorials/#iweb-design-55
...it may be worthwhile upgrading to avoid problems with post-publishing edits.

VGA/XVGA/DVI - tech questions

This is not a question about displays as such, but their interconnection. I hope this is a suitable forum.
I want some technical info on the VGA, XVGA, DVI, RGB and the twenty or so other connectors available for displays (including TVs)
Particularly I want to know details about the VGA connector on my iBook. Is VGA a digital output? What is it's resolution? If it's not a digital interface and is simply an RGB signal, why so many (15) pins?
A friend wants me to hook my G4 to his LCD TV and compare the DVD playback from the iBook and his DVD player. His TV manual talks about using an RGB/DVI conversion cable when driving the TV from a Mac. It shows a 15 pin RGB cable (like the connector that comes with the G4), yet the DVI end of the conversion cable has 24 pins.
All very complicated. Can anyone direct me to a site that would have technical specs for VGA & DVI plugs: ie what pin is what.

"what pin is what."
I just Googled for these two links of the pinouts. I'm sure there is a lot more if you want to search.

Question about data file folders in Numbers

I have created a Numbers spreadsheet ot create acataluge of my books. The file is simply called Books.numbers.
I now find on my desktop two folders - Books.numbers.sb-be4ae974-2tdLVg and Books.numbers.sb-be4ae974-A7nKNd. The former has sub folders called Data, Index and Metdata. The other has a Metadata dubfolder and several Preview.jpg files.
What are these folders, and do I need to kepp them. Doe sNumbers always create such folders?
Thanks

GF,
You may have a third party app on your system that automatically expands zIp files. If so, this app could be causing this problem because a Numbers document is in fact a Package file that appears to be a compressed file to some programs.

Tech question re: stealth mirroring MacBook to HDTV?

Greetings Apple family,
I understand how to mirror using the HDMI very well, that is mirroring exactly what is on my MacBook screen to the HDTV. My question therefore is, would it be possible to mirror for example only a Safari screen shot to the TV, while I'd be working on a Word file on the MacBook?
Thanks for the anticipated co-op everyone!
God bless,
Chris
Gr. 7 Teacher

I think you can do it.
While you're plugging the HDMI wire, go to Apple - System Preferences- then select Disply.
Next go under Arrangement and adjest your displays secreen. Choose one to display Safary and the other to work on whatever you want.
I hope this is work!

Rambeling Question...LR folders on Mac to LR on PC?

LR running on my Mac.
Ext. LaCie HD back-up
I am documenting the construction site of building. And I manage the job-site images (12k+) in a folder I have created in LR. On my Mac.
I am planning to get a MacBook and run Parallels so I can have LR on Windows. Then slowly transfer the images from my original Mac to the Windows side of the MacBook.
Basically I have to give them an ext HD at the end so they can plug it into a PC running LR and then they can see all the folders I have created of the job-site.
Am I going about this the correct way?
I know I should have put these images on LR (Windows) from the start.
I appreciate the help! Sorry if this is confusing.
-sb

I believe there is an easier way. Use a PC-formatted external hard drive. The Mac should still be able to read it. Move the LR catalog and images to it by dragging the folder from your Mac to the external drive. Then LR on your Mac and on their PC should be able to open the catalog and view the images. Try it to verify things of course. Good luck!
