Hello guys,
I want to ask about input and output with FileSystem:
1. Example for images or photo conversion:
Open Input from UserDirectory -> mypic1.png
Choose into output from UserDirectory -> MyConversion -> mypic1.jpg
I click "Convert this:
App Air can write new file by input orginal file. IS it possible?
2. Example for programming languages:
Open Input like this myproject.as
Choose Output "myproject.mxml"
And more possiblities?
3. Example for Decompilers like Model, Maps and more ....
I have problem becasue it can not change by filefilter:
Input from mymap.bsp for Half-Life ( Valve Software, Steam -> Half-Life )
Output in mymap.bsp_dec.map.
Why does App Air not work?
I tell about File, FileStream and FileFilter:
1. Figure Photo:
I want to say because i have been tried this code

That is for my workstation. But i have problem becasue output can not create new file like "mymap_dec.map" from orginal file mymap.bsp.
But App air has been created an output "mymap.bsp_dec.map". It is worng. I want make currect of output file "mymap_dec.map". How do i fix?
And how does App Air read this bsp file like wad ( Texture package for Half-Life ). If my App Air find currect wad file and back folder /maps to / and App Air will find wad file like this.
Contents:
/maps/mymap.bsp <- this is input by App Air
/half-life.wad <- Texture Package for Half-Life ( Created by Valve Software )
...
Can App Air find important files when App Air FileStream will write new map file
Content:
/maps/mymap.bsp
/maps/mymap_dec.map <- Created and written by App Air
/half-life.wad
Is it possible for 2 Files and 1 FileStream?
Like this example for conversion and decompilers 
I hope because you can help me when i can fix this <filename>.<input-extension> to <filename>"_dec".<output-extension> or <filename>"_con".<output-extension>
Best regards, Mister Eckervogt
add _con
