This tool will lookup files on the Galaxy server machine, including mounted directories.

Only directories and ending combinations set up by a Galaxy admin can be listed or loaded in this way.
These endings are case senitive.

====

The data options will look for all files that have a particular ending in the selected directory.

The tool will return two things.

1. A Dataset collection of all the detected files. (If data requested)

2. A file with the names of all the detected files. These will be sorted in the same order as galaxy builds the dataset collection. 

The files can be filtered by setting a specific start string for the file name. 
Only files that start with this string (case senstive) will be included.

Files can also be filter for the last part before the file extsentions.

Assuming the directory has:
C01_R1_001.fasta   C01_R2_001.fatsa   C02_R1_001.fasta   C02_R2_001.fatsa

Setting start C01 will return just the C01 files:   C01_R1_001.fasta   C01_R2_001.fatsa

Setting last R1_001 will return the read1 files:   C01_R1_001.fasta   C02_R1_001.fasta

As Galaxy detects the file type based on the extension this tool will change the exstension as setup by the admin.

This tool will unzip gz files if requested to by the admin,
