I am trying to use wildcards/regular expressions to identify multiple FFS files to read through one FFS reader in the FME workbench. If I use something like "C:\\SomeDir\\*83.ffs", the FFS reader reads all files that end in 83.ffs in the SomeDir directory. I can even use "C:\\SomeDir\\*8[345].ffs" to read all files that end in 83.ffs, 84.ffs, or 85.ffs. Now I want to read all files that end in 11.ffs or 83.ffs. When I try "C:\\SomeDir\\*(11|83).ffs", I get an error message "Invalid FFS dataset directory 'C:\\SomeDir\\*(11|83).ffs'". I have also tried a comma, semi-colon, or space separated list of filenames to no avail. Is this possible or do I need to create two FFS readers?
Any suggestions would be appreciated! I'm using FME Desktop 2013 SP1.
