I don't know whether this is right component. My picture collection is kept on a NAS (ca. 16000 pictures / 160 folders) which is linked as drive X: to Windows(album folder: NAS-photos. The database is managed with MySQL. I have switched off automatic scanning on restart. Now I have the following problem: if Win10 switches into power saving mode, digikam shows only the trash-box as the content of my album folder afterwards. Due to this behaviour I have to resan my whole collection for updatings digikam. Having taken a look to the database content I realized, that the content in table "albums" has been gone so digikam can't find the link between a picture and the respective folder where it is kept.
