[digiKam-users] Failed to rename Album

[Alan H]

Greetings all,
After following up on the suggestions provided (except for APIs of which I know nothing), and just trying various renaming scenarios, I rather randomly ended up at Maik’s third point (I think) of “a preview image was previously opened in digiKam”. If, in a collection, I open/preview a photo I am blocked from renaming (Failed to rename Folder error) any parent folder higher in the hierarchy above the folder in which the photo was previewed. But, I can rename the photo in the child folder in which the photo was previewed, and all other child folders at the same level, if that makes sense.

Maik, Gilles, have you had a chance to look into this - is this something that can fixed? I understand with the covid-19 pandemic that you may have other priorities. Can I at least safely rename blocked folders in Windows file explorer until there is a fix? With thanks, Alan.

Maik,

In my office, i had a Windows computer running under Windows 10 with a
huge Qt based program dedicated to record measurement files in local
before to upload data in a remote database.

While this process i remember that local files cannot be cleaned in
local when uploading was complete. The file remove was based on QFile
class if i remember. The origin of the problem was the desktop search
engine from Windows running in background which look files in
parallel. In fact when you write a new file somewhere, Windows open
files in background to parse contents and reference metadata in a
search engine database.

Possible solutions :

1/ disable the search service from Windows
2/ set the search service to ignore specific  paths
3/ use a Windows API before to create new file to be ignored by the
search engine.
4/ use a Windows API to force to unlock file in all cases.

Note : the Windows file unlock mechanism is not managed by Qt API for
Windows. I remember to see a bug reported in Qt about this problem...
