I'm not saying there's not a better way to do it. It's just the way that's developed for me. The current list of functions in that module are:

OSmkdir 
OSpath 
OSrmdir 
OSworkdir (Make a temp directory in $TEMP with unique name)
OSlogger 
searchReplaceCopyFile 
printEnvVars 
debug 
getFileExt 
getEnvVars 
OScopy 
OSdelete 
singleDosDelim 
file2Array 
arrayRelevant 
getShortPath
shortDirName (Dos 8 letter dirname)
OSrecursiveCopy 
OSmkWritable
