I am slowly migrating into using Digikam as my primary photo manager. I wrote a blog post a while ago which details where WPG writes the metadata to in the file and how to access it using Exiftool which may be of help - <a href="https://jmoliver.wordpress.com/2017/02/12/accessing-windows-photo-gallery-metadata-using-exiftool/" target="_blank">https://jmoliver.wordpress.com/2017/02/12/accessing-windows-photo-gallery-metadata-using-exiftool/</a></div><div><br></div><div>- It is my understanding that for JPG files File Property Keyword metadata is written back to file, unless of course the file or folder has a read-only attribute enabled.<br></div><div>- Digikam should be able to read XPKeyword tags (legacy Windows XP metadata locations), do make sure you have you have Exif.Image.XPKeywords for Read and Write operations in Digikam's Metadata Configuration (From the menu bar click on Settings -> Configure Digikam, click on Metadata and in the Advanced tab click on "Tags" on the dropdown) as having "Image tags" checkbox enabled in "Write this information to the Metadata".</div><div>- I recently stumbled upon an issue in which for some files the metadata was not read by Digikam. After some research, I discovered that if images were edited in WPG (Example: Straighten image, adjust contrast...) or WPG "Geo Tags" added, certain oddly crafted XMP metadata would be written back to the file which has been problematic to other applications such as Digikam. In Digikam, the XMP file metadata will not be read and thus not displayed. To correct the issue, I used Exiftool to "rebuild" the file XMP so that Digikam could be able to read it. The problem and how I was able to mitigate this issue is detailed in this Exiftool forum post - <a href="https://exiftool.org/forum/index.php?topic=12367.msg66881" target="_blank">https://exiftool.org/forum/index.php?topic=12367.msg66881</a></div><div><br></div><div>Hope this helps, and as always, when performing file modification operations, do make sure you have a backup of your files.

Hopefully someone with more experience can point me in the right direction. <u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Over the past 20yrs, I have primarily used Windows File Explorer to tag photos. In the past I’ve also used, on occasion, Shutterfly local tools and Windows Photo Gallery, both of which have become defunct. When I view pictures in File Explorer or Windows Photo Gallery, I see my tags in the Details pane. I can use the File Explorer search function to find all pictures with those tags. <u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Yesterday I discovered that for SOME pictures (on various cameras) the tag/keyword had been written into exif field XPKeywords. For a small set of pictures, the tag is written into the IPTC Keywords field; I believe these are pictures I tagged with digiKam or with ExifDateChanger Pro. But for the VAST MAJORITY of my pictures, the tag is just in the Windows File Properties Tag/Keyword, not in exif or iptc. I also used IrfanView to view the exif & iptc information to try and verify what was present in the file metadata. <u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">digiKam does not seem to read the Windows File Properties fields so I can’t search for pictures by my tags.<u></u><u></u></p><p class="MsoNormal">My pictures are taken on 10+ cameras and have various Exif versions over the years, but the problem exists across all of these. I have pictures from 2020 with that XPKeywords field (with my tag in it) in the exif data, and other pictures from 2020 without it (that I had never tagged), so this isn’t just related to older or newer pictures. The issue spans all years, all cameras.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">I tried going to digiKam Tag Manager Tool > Read Tags from Image – but no luck.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Is this a bug in digiKam?
