Description herb 2016-10-09 16:17:49 UTC 
Hello,

I work with digiKam 5.2.0 on a Win 7 system.

As far as I understand the digiKam documentation digiKam stores all its data - thumbnails included - inside of database files.
But in directory c:\user\USER\.thumbnail\large I found lots of *.png thumbnails.

In case of digikam (or showfoto) do not need these cached files within the next session, for a better housekeeping it would be very helpful to delete these file atleast at end of a session.
In case of digikam (or showfoto) need the files in its next session these thumbnail should be stored in a subdirectory of database directory (selected by user). 

Thanks in advance and Best regards
Herb

Reproducible: Always

Steps to Reproduce:
1. Work with digikam and/or showfoto with images newly found inside an album.
2. Look at directory c:\user\USER\.thumbnail\large
3.

I'm sure. These files are not generated by digiKam.

Try to remove it and restart digiKam, just to be sure.

Hello,

thanks for your quick reply.

I was very sure that these files are created by digiKam, because the string digikam is part of the filename. 
The files are created by showfoto:
I started showfoto, opened a directory with 8 *.jpg images and closed showfoto.
Now I found 32 files in directory c:\user\USER\.thumbnail\large.
A typical filename is as follows:  6baabcf91d28667d3c72293b43499e06.png-digikam-ER2644.png

Best regards
Herb

Well for Showfoto, it's normal. Showfoto do not support database and use freeDesktop standard to generate thumbnails.
