Smile4ever: moved Get extention of file to Get extension of file

{{PageAuthor|opher}}

== Description ==
This is based on the work of Afrow UK.
This more accuretly reports the extention:
For path "C:\some dir\some file with no extention"
Afrow UK's implementation will return the original string as "extention"
For path "C:\Installation.CD\some file with no extention"
Afrow UK's implementation will return "CD\some file with no extention" as extention.
In both cases this function will return "" (empty) as extention.

== Usage ==
<highlight-nsis>
Push "C:\some path\filename.extention"
Call GetFileExt
Pop $R0 ; $R0 = "extention"
</highlight-nsis>

== The Function ==
<highlight-nsis>
Function GetFileExt
Exch $0 ; input string
Push $1
Push $2
StrCpy $1 0
loop:
IntOp $1 $1 - 1
StrCpy $2 $0 1 $1
StrCmp $2 "" empty
StrCmp $2 "\" empty
StrCmp $2 "." found
Goto loop
empty:
StrCpy $0 ""
goto exit
found:
IntOp $1 $1 + 1
StrCpy $0 $0 "" $1
exit:
Pop $2
Pop $1
Exch $0
FunctionEnd
</highlight-nsis>
