Do yo u mean that Windows is not case sensitive with directory names ? Which files system do you use to host collections on your disk ? NTFS or FAT ? Gilles Caulier The problem is reproducible with image files naming in one album ? Created attachment 109288 [details]
1) initial file/folder
folder "example" (lowercaes)
Created attachment 109289 [details]
2) lowercase folder in digiKam
Created attachment 109290 [details]
3) rename folder to uppercase in explorer
Created attachment 109291 [details]
4) both variants visible in digiKam after restart
Created attachment 109292 [details]
5) move one folder into the other in digiKam
Created attachment 109293 [details]
6) recursive directory structure
filesystem is NTFS (case insensitive) - digiKam seems to think it is case-sensitive From wikipedia page : https://en.wikipedia.org/wiki/Case_sensitivity "The older Microsoft Windows filesystems VFAT and FAT32 are not case-sensitive, but are case-preserving. The earlier FAT12 filesystem was case-insensitive and not case-preserving, so that a file whose name is entered as readme.txt or ReadMe.txt is saved as README.TXT.[6] Later Windows file systems such as NTFS are internally case-sensitive, and a readme.txt and a Readme.txt can coexist in the same directory. However, for practical purposes filenames behave as case-insensitive as far as users and most software are concerned." This want meant that even if case sensitivity exist, Microsoft ignore this point voluntary. This is typically a big mess as usual from M$... Gilles Caulier Can you reproduce the dysfunction using digiKam 6.0.0 pre-release bundle available here : https://files.kde.org/digikam/ *** Bug 398674 has been marked as a duplicate of this bug. *** This is really an interesting problem. At the moment I do not have a solution to not restrict Linux and OSX users. To rename the album under digiKam works without problems and should be done as a workaround at the moment. Externally renamed makes the problem because digiKam can not determine that it is the same folder. Because "Friends" and "FRIENDS" each return a "QFileInfo::exists() == true". Maik Can you reproduce the dysfunction using the last digiKam 6.0.0-beta3 just released ? https://www.digikam.org/news/2018-12-30-6.0.0-beta3_release_announcement/ (In reply to caulier.gilles from comment #14) > Can you reproduce the dysfunction using the last digiKam 6.0.0-beta3 just > released ? Have there been any commits to resolve this issue? I'd rather not try to destroy the filesystem on my production machine intentionally Created attachment 122448 [details]
scanDirs.patch
This patch fixes the problem. I'll test it internally, because the code is critical for the database if it does not work properly.
