Hello TH, Galaxy currently doesn't consider the name of a file on disk. If a file is uploaded, Galaxy creates a copy of the file in it's own configured storage location ( the default is ~/galaxy install dir/ database/files/... ) using it's own naming convention to name the copied file. Galaxy supports many different data types, and internally uses a variable named "file_ext" when associating a data type with a file, but that really has nothing to do with the name of the file on disk.

Is file type association case sensitive? If file extensions "abc", "ABC", "Abc" represent the same data type, is it also like that in Galaxy? If not, how can one modify Galaxy to do that?

Thanks in advance,

TH
