<div dir="ltr"><div>I am revived user low on the learning curve andbut I can respond to how I repaired a moved collection by going directly into the digikam4 data basefile. I have no experience in using the migration tool but I did grab a 2 year old collection and the files for digikam6 installation out of a backup location. They had been living on an even older workstation hard drive and I hoped that the collection would just operate by firing up the collection from a backup. Digikam6 did fine to display the thumbnails for the identical recursive tree of folders and file images... but it could not deliver the full image preview. I guess it could get to the thumbnails directly through the thumbnail database.</div><div> Not understanding the migration tool..I installed DB Browser and studied the database field called AlbumRoots</div><div> It has and identifier field and a path that allows the digikam display tools to fetch the proper full image .</div><div> If ound that the identifier retained in the digikam4 was pointing to a UUID for the hard drive in the old workstation</div><div>I had also moved the identically named folder and file collection under a new top level folder rather than root.</div><div>The field titled "specificPath" perhaps should be titled "completePath" from root.</div><div>To be safe I moved my identical folder collection to drive root (where it had resided on earlier workstation) instead of trying to add the toplevel folder to the specific path<br></div><div> The format for the 2 fields identifier and specific path is</div><div> volumeid:?uuid=NewHexstring /identicalFolderCollection</div><div> With those 2 fields set digikam happily treated the moved collection as a native home.</div><div> My post about this is on the inactive other digikam forum<br></div><div><a href="https://forum.kde.org/viewtopic.php?f=256&t=173758">https://forum.kde.org/viewtopic.php?f=256&t=173758</a></div><div> I am a learner non programmer grasping for bits of info and I was relieved to find this direct way of repairing a collection and database which is identically positioned in a folder tree, but moved without advance planning.<br></div><div> I am sure the many helpers on this list have addressed this structure in past postings,</div><div> but the info is buried in the past until these email threads are gathered into a unified searchable document.</div><div>Ty<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jan 25, 2022 at 3:42 AM frederic chaume <<a href="mailto:frederic.chaume@gmail.com">frederic.chaume@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi All<br>
<br>
my current Disk is going to be out of sapce and I would like to move all <br>
my collections (~50) from current Disk to a new one.<br>
Then I would like to know what is the best process to do it.<br>
I see a refresh button for each collection in DK configuration, is it <br>
then enough to choose the new location ? can we do it after having moved <br>
the collections ?<br>
<br>
FYI I'm using DK7.5<br>
<br>
thanks for advices<br>
<br>
frederic<br>
