Cc Lightroom file definition

What is the difference between these two files

Previews.irdata catalogue Lightroom

Lightroom Catalog smart previews.irdata

I generate more intelligent previews. not exactly whats in previews.irdata but it is 35 GB

The previews folder contains excerpts as Lightroom users when viewing the images in the library module. The previews smart folder contains larger previews that you can use to change when the main images are not available. If you use more intelligent insights you could remove safely from this folder. If you remove the previews folder, Lightroom will begin to build again as it depends on these glimpses in the library module. You can control the size of the little previews of the size you want to use, and how long to keep them. I do not use the library module that much. I so Lightroom generate smaller previews. And I choose of the deleted after 30 days.

    So, in my words, your picture has not changed somehow in Photoshop. There is no sense and doesn't matter the number of ppi. The important numbers are pixels.

  • Nikon D7100, I can't download my RAW to Lightroom files. I have read all the post, update of 3.6 to 4.4 and 5.7 with Lightroom 2015; Nothing helps!

    Nikon D7100, I cannot download my RAW to Lightroom files! I have read all the post and started with Lightroom 3.6 4.4, Lightroom 2015 then Lightroom 5.7 update. Nothing helps!

    The Nikon D7100 is supported from 4.4 LR on-site. So I have no idea why you have problems to import files NAVE of this camera or the card memory used in this device.

    You use the Nikon software first to get images of camera or card to your hard drive? I read somewhere that the Nikon software does something for the NAVE of the files making them unreadable by LR.

  • Mysterious folder Lightroom files.

    Hello all-

    I just want to preface my question by saying: I am sorry to be the kind of user who expects a quick response / solution and then leave the forum until my next problem. I'm fairly warned with Adobe apps, but I don't think I'm at a point where I could answer other users questions yet.

    Switch, here is some information on my computer:

    I run a 2008 Macbook Pro 5.1 wit 8 GB of ram, 128 GB SSD for my boot drive and a 256GB in my old optical Bay that I use as a storage drive. I have Lightroom and all my apps on this disk "storage" for the storage of large files.

    And here my question:

    Over the last year, I flooded my folder Lightroom file cache. I think that I did of my Lightroom folder to another drive with the opening of the synchronization application. What is a reasonable explanation for what could have happened? I'm also sure about some other files.

    I am aware that I need the following:

    -Corrupted catalogs

    -.lrcat files

    I don't know if I need any other files like "temporary import data" or "repair temporary catalog".

    I've attached screenshots below. I would really appreciate the help

    You can permanently delete the Lr2 and 4 files catalog and Catalog.Previews if you're ABSOLUTELY positive you have upgraded their and no longer need them.  Temporary importation and the TemporaryRepairCatalog are files I've ever seen, but it is probably safe to delete also.  What is in the folder catalogs to corrupt? If it is no longer necessary because you have repaired your catalog that you should be able to remove it also.  You can move these files to another folder temporarily and see if Lr works very well.  If so, then delete them.  I'm glad it works for you.

  • Lightroom files deleted (permanently) everything by moving

    Today move some files and by organizing on a regular basis, I noticed one of the files that I had moved just stood as a missing file.  I had looked and worked with these photos before, so I know they were there.  I had not deleted since Lightroom or my hard drive.   The files have been moved to Lightroom, and then disappeared.

    I have searched all over my computer and external hard drive, and they aren't there!  Silly me, it was a recent shoot and I had not yet made a backup.

    So, I called Adobe customer service. NEEDLESS. Had no constructive options for troubleshooting.  Basically, anyone with basic computer knowledge could have done what they were trying to do and done better.  I had already searched computer, trash, drive hard etc, the files do not exist.  I need options to recover the files.

    All the support guy might say, and this is a supervisor at that time, was that «the Lightroom deletes pictures»  Have you read the forums?  How "BOLD" to say it could never happen, or is it never happened!  How about trying to solve the problem.  In my own research I found a way to extract my glimpses, however only about 20% of them are recoverable. The support guy could have asked me if I had seen 1:1 and then he suggested that I extract these since they would be a viable file.  He didn't even know that was an option.  Her exact words were "Tell me where your files are, and I'll show you how to get back them."  If I knew where they were I wouldn't be looking for them!  The customer support was completely useless. The WORST customer service experience, I never treated.

    In regards to Adobe... it's a crime.  You do pay a LOT of money for your products and do not offer support for these products. If you people answering phones that really understand the product and spoke English, your customers would have a chance to reconcile their questions.

    I searched my computer and the hard drive for the missing files. I tried to extract previews recoverable with some success.  I get files from my hard drive in the hope that they can appear here. Any other suggestions would be greatly appreciated.

    Frustrated customer.

    Unfortunately, this bug has been reported several times, that doesn't happen a lot, but it's a very serious bug. In fact, the only time where I know that Adobe have sought the bug, they claimed that it could not be reproduced. As far as I know, your photos have disappeared.

    Documentation of the bug is here:

    Transfer of photos to an external hard drive, lost photos

    Another case is here:

    Files disappear while driving, the files in Lightroom for Mac to HD. Can anyone help?

  • Mobile sync Lightroom files

    I organize all my iPhone per month 6plus photos, and then synchronize them with mobile office via lightroom lightroom (please let me know if you have a better way to save photos).  I had a lot of problems with synchronization stuck.  In the past, I deleted the file sync, disconnect and connect back, deleting the collection, uninstall the application.  But this time, none of them works.  My office is showing 10 to be synchronized, and blocked to 309 to download mobile.  I spent almost all day trying different things without success.

    In addition, another question.  The collections that I created are displayed as separate collections on the cloud of lightroom, but it seems to be in a huge collection on the desktop.  Is it possible to synchronize the individual collection on the desktop?

    Thanks in advance!

    Hi lulut,.

    We recommend the workflow in the face.

    First, import images desktop > once the import is finished, add images to their respective collection (according to your choice)

    > Synchronize the mobile collection to Lightroom and make any changes.

    Following the workflow that above, you have all your images saved on the main machine and you use your mobile phone only for editing.

    Hope that helps.

    Kind regards

  • How can I delete mobile device via Lightroom file? NG

    I use Lightroom Mobile to take photos in Raw on my mobile device. This allows to save a. DNG file on my device. However, several times after going through the photos I want to delete these photos permanently. However, I notice when I tap a photo and click on 'remove picture' on the device, it does appear in the Lightroom application and is not physically delete this photo on my camera?

    Can I delete these photos my camera through the application without having to go to the folder on the device?

    Thank you.

    After talking with tech support, it turns out there is no option to remove the original device file, as you can do on the desktop version.

    I'm afraid to tell Brandon but we do not have an option to remove photos from the mobile site of origin both through Lr. »

    It is regrettable and very difficult to manage to go through file and remove as much as my phone does not display manually. DNG natively. I have to delete or remove the photo from Lightroom Mobile indicating the file name then outside of Lightroom Mobile I have to navigate to the location of the original file on my device find this file name and remove it from the device.

  • Lightroom files have? brand and are not found

    When I need to change a root folder either by renaming or moving on the main hard drive, lightroom loses connectivity. This is not a problem in itself, but how can I remove the reference to the lightroom folder and download the new location of the file or the name?

    You like LIghtroom to reconnect to the record by (in Lightroom) right click on the folder with the? icon and selecting then find the file missing and then showing the real location and the name of the folder.

    You might consider renaming the folder in Lightroom, or better yet, develop a "workflow" that requires no change of name of folders.

  • Cannot save the Lightroom files after editing in Photoshop CC (or they are invisible).

    When I export a file from Photoshop CC 2015.1.1 in Lightroom, the "Edit a copy" screen does not appear.  The image opens in Photoshop, I make the changes, press on save, close Photoshop and I went back to Lightroom with no new image modified either because it has never made a copy in the first place the new file edition is invisible (see below).  Spent hours on the phone with Adobe and we theorized it was multiple copies of Photoshop on different drives.  I physically removed all disks except one, and the problem remains.  Have uninstalled and reinstalled several times. I have the latest version at all (it started with c. 2015.1.1).  Photoshop 6 works very well and doesn't have this problem, although I have copies of 6 PS on several other non Adobe software players works fine too.

    If there is more than one custom "slot" for external editors in Lightroom, I wouldn't even post this question because I could bypass Photoshop CC entirely.  But as it is, one of my two choices of editor external links Photoshop CC.

    Tip: If I put the file in the quick Collection, things are like the old days.  I get the screen to export, a copy is created, modified in Photoshop CC and when Photoshop CC is closed, the modified version is visible in Lightroom.  However, when I try to move the file edited in quick Collection in the folder where it belongs, Lightroom says that it's already there - which it may be, but it is invisible.

    P.S. I just discovered that it IS possible to specify more than one external editor, this is a temporary solution, given that I can use Photoshop 6 and like many other apps I want instead of PS CC.

    If Photoshop is the main editor in Lightroom, it will not ask to create a copy for raw images.

  • How to import files in lightroom - "files cannot be read" help!

    Hello...

    tried a few forums.  Am more recent ligthroom and os operating 10.10.5.  Since I installed lightroom creative cloud I have not been able to import files.  I can get an overview of the files.  Files successfully imported on the old version of lightroom but can not yet open on new lightroom.

    So far have tried:

    Uninstall and re-inistalling

    setting preferences so they are ready to read and write - library, creative cloud, lightroom

    Import via other means (but my technical skills could be missing here).

    Would appreciate any help

    Thank you

    Thanks assani

    Appreciate the suggestion, but it didn't work.  However, it led me to a work around.  In case everyone takes up this thread: I selected the files, I tried to import directly from the SD card and then choose 'Open with' and lightroom.  It then allowed me to import.  Not the exact solution I was hoping, but at least it's a work around.
