sidecar file names

[frederic chaume]

just made few test today

"sidecar file names are compatible with commercial product" set to OFF,
run a maintenance tool on a test folder : synchronize from database to 
image metadata

result is
DJI_0638.DNG
DJI_0638.xmp
DJI_0638.DNG.xmp (created by the maintenance run)

Digikam is using the one which is dependent of the parameter, so "no 
problem" , but I'm using another photo editor (DXO) which require the 
DJI_0638.xmp to be removed

seems workable , but it will require lots of time to create those new 
xmp (DJI_0638.DNG.xmp)  and also it will require to remove the previous 
xmp (DJI_0638.xmp) which may not be easy under windows

any such experience ?

thanks
frederic
