Hi,

I have LR five. I'm getting the "error when reading from its preview cache" message. In the interest of honesty, I Googled on the problem and came upon some Adobe posts on the topic from three years ago. The problem is, the suggestion that one should remove certain files did not seem to work for the person making the complaint. So here are my questions: Has anyone used the remove file method and been successul regarding the problem (I'm deathly afraid of removing the wrong files)?  Has anything changed in three years that makes solving the problem easier? How do you get in contact with an Adobe technician for a chat (this is the only thing that worked for one person)? Anyone have a phone number?

Thanks, Al Marotta

This is the forum for Lightroom, the cloud-based Lightroom that stores images in the cloud. Adobe has confused many users by their naming convention. However, since you are using Lightroom 5, I will attempt to answer your questions. The file that has begun to cause you problems is the previews folder which has the extension .lrdata.

 

It is the only folder that you need to delete. It is located in the same folder that contains your catalog. After you delete (or simply rename that folder if you prefer) that folder then Lightroom will rebuild your previews folder. Adobe does not provide support for Lightroom 5 anymore. It wouldn't do you much good to call Adobe because Lightroom 5 is not a product they will offer ANY support for because it is ancient history, not under development, and no longer supported. The only place you are likely to receive support for it is on this forum. If you rename that folder rather than delete it, if the rebuilding process doesn't work as expected then you can simply rename it back to what it was previously and everything will be as it was and you can pursue some other solution. But I suspect the solution I have suggested is what is needed.

hI jIM,

Thanks for responding to my lightroom post. I need to point out before
continuing that I send all my lr5 pictures to an external drive. I did a
search of the external drive and came up with about 8 "Catalog
previews.lrdata" I changed the name to a couple of them--including the
latest one-- and now none of the pictures come up in light room. What
comes up is a few pictures I downloaded in the /C /drive back when I
first used LR. In other words, now lr opens up fine, but not with all
the pictures I've shot over five years or so and are on my external
drive. Any thoughts on the matter?

Again, thanks,

Al Marotta

Is the catalog you are using on the external hard drive?

Hi Jim,

As far as I know, the catalog I use is on the external drive. I say "as
far as I know" because computer matters confuse me.For the past five
years whenever I've downloaded pictures to LR, I send them to my
external drive. If there's some way the catalog is actually on my pc and
not on the external drive, please tell me how to find it.

BTW, could you tell me which LR program today is the equivalent on LR,
just simple for the basic user?

Thanks,

Al

"Normally", the catalog and its associated files are stored in a Lightroom folder inside of the Pictures folder on the main hard drive on the computer. That doesn't mean that the catalog must be in that folder. That is the default folder where the installation process puts it. The previews folder we are discussing would be in that same folder. But since you renamed folders on the external drive, and that has changed what you are able to view in Lightroom, that makes me suspicious that your catalog is on the external drive. That's why I was asking.

 

There are two different versions of Lightroom today. You ask about a "basic" Lightroom. The version that operates similarly to what you are accustomed to is Lightroom Classic. It is part of the creative cloud program. That does not mean that the program is in the cloud. It is delivered to you via the cloud, but it is installed locally on your computer and functions much like the Lightroom 5 you have been using. It has many new functions that your version does not have and has the additional capability of sharing collections on the Web if you choose to do so. It is not possible to purchase Lightroom Classic out right. There is no version of Lightroom that can be purchased. All Adobe products, except for Photoshop Elements and Premiere Elements, are part of the creative cloud system and are only available via subscription. The basic photography plan includes Lightroom Classic and Photoshop, and is $9.99/month in the US, with a minimum one-year commitment. There are additional features that are included such as a mobile version that can be installed on your phone and other mobile devices, but I won't try to go into details on that aspect unless you are interested in learning more about that. A lot has changed, really a lot, since Lightroom 5.

Jim,

From the bottom of my heart, thanks for your wonderful help. You must
know how that goes----you get mental about a problem your having and
would do anything to solve it and thanks to your continuing help I did it!

I actually don't know what I did. I renamed the folder of lightroom
previews.lrdata. Then I discovered, from your hinting, that I was in a
different catalog. So I relaunched to my external drive catalog and all
appears to be well (although another previews;lrdata filed showed up
right away).

Thaks for the words about LR today. I'm gonna hang onto five as long as
I can.

I wish you a good year of happy shooting.

Al

There will always be a previews folder. By renaming or deleting the previews folder, Lightroom is forced to create a new one. I hope that resolves your issue, and I hope Lightroom 5 continues to serve you well. However, holding onto Lightroom 5 could be holding you back. There have been several processed version updates and numerous improvements that have definitely made an improvement in what I have been able to do with many of my images. Maybe that isn't a consideration for you, but there it really is a noticeable difference that, in my opinion, is well worth the money. And you get periodic updates as part of that subscription fee. But if you are content with Lightroom 5 then so be it.
