Examples for regular expressions used for replacing:

source_file	file_spec	replacing	replacement	Example Input	Output	Comment
./temp	.*	~	""	hallo.dat~	hallo.dat	-
a.txt	-	[.]txt	_2011-11-24.txt	-	a_2011-11-24.txt	-
./temp	.*	.*	[filename:] [date:yyyy-MM-dd].dat	a.txt	a.txt2011-11-24.dat	[filename:] and [date:] will be substituted after file has been replaced
./temp	.*[.]txt	a.*?b	world	a.1.b.txt.b	world.txt.b	.*? : ungreedy usage of .*
abcdefg.txt	-	^(ab)cde(fg)[.]txt	123;[date:yyyy-MM-dd]	-	123cde2011-11-24.txt	; : separator between multiple replacements
./temp	.*dat$	(ab)_c[0-9]d_(fg)	group1;group2	ab_c1d_fg. ab_c2d_fg.dat	group1_c1d_group2. ab_c2d_fg.dat	Only the first pattern match is replaced
./temp	.*	^(?:aa|bb)_. {2}_([0-9]+_[0-9]+)$	tail	aa_QU_061205_222334	aa_QU_tail	(?:...) : "?:" specifies a non capturing group. The file will not be replaced.
./temp	FILE.txt	.*	[filename:lowercase]_[filename:uppercase]_[filename:]	FILE.txt	file.txt_FILE.TXT_FILE.txt	-

source_file	target_file	file_spec	create_dir	replacing	replacement	Example input	Output	Comment
aaa/bbb/	[directory:]/[date:yyyyMMdd]/	hello.txt	true	[.]txt	[date:yyyy].txt	aaa/bbb/hello.txt	aaa/bbb/20070316/hello2007.txt	If the directory aaa/bbb/20070316 does not yet exist it will be created
