Description Will Stephenson 2009-09-16 14:28:39 UTC 
Version:            (using Devel)
Installed from:    Compiled sources

Eg in the file overwrite dialog shown by Dolphin.

This is because for some files, the metainfo is at the end of the file, which we do not handle atm.

There is no header at the start of the file saying how long the data is to seek to where the metadata is, the trailing x bytes are the info, so you need to read to the end to know where the info starts. and then there might be no info (95% of cases i think).  

A kfile implementation should start by checking that it is a real file and not a stream: open file, go to end, go back x bytes, check if data matches metadata format, etc.
