• Cannot reduce the size of previews.lrdata

  Hi all

  My Previews.lrdata folder is 45 GB. On a 500 GB SSD (end 2013 15 "MacBook Pro retina), it is a reasonable piece.

  So I went through and used the menu option "ignore surveys 1:1..." in all the pictures that I do not expect to change again. Somewhat to my surprise, the Previews.lrdata folder did not file size of 1 byte. I used the option "optimize catalog", but that doesn't seem to do anything either.

  I prefer not to empty the cache of the preview while suppressing the Previews.lrdata, regarding the last pictures I've not edited and yet I enjoyed having to previews pre-rendered 1:1.

  I don't expect too much here? Should not be a relationship between throw me 1:1 previews and a reduction in the size of the Previews.lrdata folder?

  Thank you

  That is right.

  ntompson wrote:

  What are the downsides to this?

  No - your standard previews have been set too high before.

  ntompson wrote:

  Why have a standard preview at all?

  For reasons of performance - faster to enter/resize some smaller if he wants to.

  ntompson wrote:

  Would I better off put the standard preview to the smallest possible size?

  Lol if you do this, then Lr re - will make a brief 1:1 for fit view, even if a standard preview was already available (because it would be too small). Certainly, if the 1:1 Preview is already available, it wouldn't need the re - make, but if you are when they expire, it may not be available, and despite this, it takes more time to load/resize a larger and a smaller preview.

  When I do the standard preview size change in Lightroom, then does invalidate all standard previews in my catalog? Does crank through and to regenerate all the standard previews to the new size?

  No and no (but in my opinion, the user should be prompted to see if he/she would like to rebuild so size or quality changes).

  In many cases, the difference over having a frame is too small or too large a framework, will be almost (or totally) without consequence. To be honest, I'm surprised that adobe exposed this option to the user, since most users have any idea what optimum setting should be. If I were Adobe, I suppose that Lr/hand-UI would be on the bigger screen and automatically size previews accordingly. Often when I mention this, people point out that the same catalog can also be used on a laptop, review how would be more optimal, and there are other considerations double monitor.., but hey - whatever...

  PS - Lightroom creates different preview (up to) 7 sizes: from 1:1 to little thumb. When he creates a large preview (1:1 or standard), he created all the smaller previews also, in halfening size. It is very fast, and no doubt explains the reason why it will not throw a 1:1 if next (standard) would be more than half it's size (it's actually only create 6 previews in this case: 1:1 through thumb, there is no big standard preview size you specified in this case) (, or if you prefer another way of seeing things: the preview of 1:1 is your largest standard preview).

  If you want to better understand what is stored for previews, you can play with the PreviewExporter plugin I wrote (free) - it allows you to specify at what level (1-7) to preview you want to export, and if you enable verbose logging will provide info on what was available, and what level of preview has been exported. Here is an excerpt of "post-process action" (export filter) UI:

• Delete "Lightroom 5 catalog Previews.lrdata Smart?

  My Lightroom folder has a 2.28 GB "Lightroom 5 catalog Previews.lrdata" file and a 10.01 GB file called "Lightroom 5 catalog Smart Previews.lrdata."

  "Lightroom 5 catalog Previews.lrdata" file was created on 09/02/13 and amended on 20-11-14.

  "5 Smart Previews.lrdata Lightroom Catalog" file was created on 09/03/13 and has never been amended since this date.

  The last time that I imported the photos 11/14/14. I did no changes what whether from 20/11/14.

  Given that the "5 Lightroom Catalog Previews.lrdata Smart" file has not changed since its inception, I wonder what, if any, it is in service. Delete would free up much of the space, so I want to do if I wouldn't lose something important.

  I use PL 5.7 for Mac, in the case where that matters.

  Thanks in advance for your answers.

  ... Previews.lrdata files (not files), are required by Lightroom and should not be deleted. I mean, they peuvent be removed if they cause problems (or they are associated with a catalog obsolete..) and they can or will be recreated, but management is to minimize the storage:

  remove the 1:1 previews, and/or

  remove smart insights

  (using the Lr menu functions)

  In addition, if you reduce the size and/or quality of the standard previews (using Lr preferences), then it will be not so great...

  That said, some of us just delete these records as a quick dirty way to 'start over' preview-wise...

• Previews.lrdata folder size

  I remember this discussion a few weeks ago, but I can't find it by searching.  Anyway, my problem, if it is indeed a problem, is that for my LR catalogs 4.1 RC previews.lrdata folder are a lot larger than the same pictures catalogued in LR 3.4.  It comes on several catalogues.  I deleted the folder previews.lrdata on the Catalog under both versions and regenerated previews, but differences remain. Any ideas as to why this is happening?

  Just to be clear on the process:

  If you had to upgrade LR4 your LR3 catalogues, everything that happens is LR4 "steals" extracts from the catalog in LR3 and renames the file found to match the name of the catalog LR4. So if you were to look at the contents of the folder catalog Lightroom immediately after the upgrade you will find the original catalog in LR3 but no associated file previews and catalog LR4 a previews file related... and because it's a simple hi-jack of the previews folder LR3 is of course the same size as the old folder to LR3.

  If you open the catalog in LR3 LR3, because no record of previews there is now a new parameter is created and (unless you ask then LR3 to rebuild previews of images again) LR3 will create standard previews that you import photos in the grid/film. In this scenario, obviously the newly created previews LR3 will be much smaller than the old previews folder that is now labeled LR4.

  I've seen a lot of posts since LR4 came out to complain about the perceived in comparison with LR3 LR4 folder size, and I think that in many cases there was a lack of knowledge about the process.

• Should I back up the package of Previews.lrdata?

  I use LR CC on a Mac.

  Is it necessary to save the packages "Lightroom Catalog Previews.lrdata" and "Lightroom Catalog Previews.lrdata Smart? I use a service of online backup, as well as a 'Time Machine' and 'CC Clone' backup. I would like to limit the costs of downloading data, as well as the disk space on my local backups.

  I guess that these files would be just rebuilt, if they disappeared?

  Thank you

  David

  You are correct David. No need to back up. They can be generated at any time.

  Since the update of my pc based system with 10 windows and install the last Prime Minister CC when I drag a clip on the timeline audio does not come with it. I can hear audio playback in the preview window of small file so the audio is there, but it does not appear or play on the timeline. I can drag an audio file of Ms on the timeline, but I need audio from my original file to synchronize my audio file recorded independently - used to be no problem... any ideas what I can not edit now?

• How can I change lightroom 5 previews smart on the book of mac pro (mbp) when lightroom master image files 5 are on my external hard drive is disconnected from the mbp

  How can I change lightroom 5 previews smart on the book of mac pro (mbp) when lightroom master image files 5 are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external hard drive the mbp, I get the pop following window: "external hard drive A" disc could not be ejected because it uses 'Lightroom '. Exit this application and try out this disc again. When I do that and restart Lightroom 5, Adobe Photoshop Lightroom - screen select catalog appears, but does not list my external hard drive A as a choice.

  I've been reviewing Adobe's Lightroom Help | Smart web page Previews Lightroom 5 and still have not been able to understand what I am doing wrong. Any help would be appreciated.

  HI Thomas,

  Thank you very much for your suggestions! They finally gave me the direction I go solve the problems I had. Basically, the Mac Book Pro based Lightroom irdata files still had thumbnails. Once I removed the and redirected Lightroom external hard disk, smart previews of the external drive work when the player is well off the MBP. Much obliged.

  I was wondering if you have any suggestions on how to backup all the files content and related data of Lightroom that exists on the external hard drive to another external hard drive as a backup? Ideally, it would be great if I could be able to launch security HD since the Mac Book Pro and do the work of Lightroom with the backup image files and intelligent previews correctly. Thanks again. Your help has been invaluable.

• Several files "Previews.lrdata".

  I store my catalog on a dropbox files directory that synchronizes to multiple computers. Therefore, there were several cases where conflicts took place with the catalogue being opened on both machines. Dropbox usually creates a copy of the catalog with a changed name to receive the catalogue being open on two machines. Inevitably, lightroom will create a new Preview file (.lrdata) for the catalog.

  I have since then become a Falcon on never open the catalog on both machines at the same time. But I'm stuck now with a bunch of preview files of .lrdata I'm afraid to delete in case they relate to my main somehow catalogue. My files end up looking like this.

  

  The current catalog is called "_All Photos of all the time_Current.lrcat" I wonder which of these preview files I can delete.

  Thank you!

  Johnny

  Actually, you can remove all or part of them, and this will not affect the work you have done. Lightroom just get started create a new series of previews while you work in Lightroom.

• LR previews.lrdata files

  I understand that the LRCAT is the main file for a catalog. In the LR4, the program generates a file preview.lrdata containing thousands of new files and take a lot of hard disk space and a lot of time when the readers of synchronization.

  If I delete all the files and preview files and reopen the catalog, LR begins immediately generating these files again.

  I have something checked (as previews full size) which is originally LR do all these files? I remember this in LR3. I looked around in the prefs and catalog for a checkbox.

  Maybe there something to the size of the preview, I chose? I had the Settingst catalog at 1440/Medium/throw 1:1 after a day.  I just put it to 1024/low/throw 1:1 after a day.

  My main catalog now has 170 000 files and the LRCAT file is approximately 2.63 concerts.

  I use Alwaysync to synchronize the disks on a PC running Windows 7. All records requires more time to analyze.

  Thanks in advance,

  M Jackson

  M,

  Lightroom has always been so. The previews on Windows were (and still are) always embedded in a large folder tree.

  As the overview file can be re-created at will, you don't have to back it up. Is there a way to tell Alwaysync to ignore it when you synchronize your disks?

• If I move an item in "Junk," can I have and then view it in the preview screen without the risk of any smart malware being released?

  I understand that malware can access my computer simply by displaying an e-mail in the "Snapshot" of my Thunderbird Inbox window. If this is true can I actually to quarantine the message by moving it to "junk"? I read somewhere that once a message has been identified as 'Junk' it is prevented from free malicious software may be incorporated. I ask this question because sometimes I'm not quite sure if the email is really undesirable, or if I'm too cautious and would like to read the message to be sure. I want to emphasize that I don't know to click on an attachment or a link, but just look one e-mail.

  re: I understand that malware can access my computer simply by posting a mail in the window 'Preview' of my Thunderbird Inbox. -you don't know where you reading, but this is not correct.

  First of all, I'll clarify that there is no "Preview" window
  'Preview' implies that the email has not been open.
  A simple click on the email in the list opens the email in the "Message pane" poster under the email list.
  A double click will open the email in a new tab or window.

  All methods open the email.

  This file the mails is not relevant - a selected e-mail opens any file.

  Default Thunderbird automatically showing not "remote content.
  By default, Thunderbird blocks remote images and other content in messages from people you don't know. This protects your privacy because spammers can verify your email address by detecting if you were displaying a remote image for a message on their behalf. Its also possible to incorporate an executable file (malware) in images.

  When you receive a message with the remote images, Thunderbird displays an alert indicating that remote images have been blocked, and the images in the body of the message will be replaced with simple place-holders

  • http://KB.mozillazine.org/Privacy_basics_%28Thunderbird%29

  So if you don't allow remote content and that you do not click on the links or open attachments, then you will be ok.

  Closer to you, I do open was important as a new project, but when I tried to open the timeline, the accident occurs. I copied the files on usb, HDD external and then copied on my local disk.

• Preview "HTML5 in the browser" does not...

  Hello

  I recently had the problem where Preview "HTML5 in the browser" does not work. All I get is the "loading" animation

  I tried several different projects using Chrome and Firefox.

  Overview "in the browser" works very well.

  Let me know if you have any ideas!

  Thank you.

  Ryan

  Hi Ryan

  You're on a PC? If so, it is quite easy to find the folder. Just close Captivate, then find the icon that you use to open the Captivate. Right click and look at the properties. From there, you should see in the shortcut at the bottom tab on the left is a button allowing you to 'open file location '. Click on that, and Windows Explorer opens. From there, find the Utils folder. Open it and you have a CleanPreferencesWin file that you can run.

  See you soon... Rick
