What is the best free batch renaming tools in windows? After testing out a few batch renaming system, SmartRename become the one I'm mostly interested in, Googling SmartRename will get you another program, because SmartRename[拖把更名器] is a Chinese program. The Chinese do, at times, create really amazing programs. Lack of translation is usually the reason they are not known outside China.
The official site for SmartRename is down, maybe for months. There are downloads of this program in Chinese sites, but I doubt anyone here can follow the extremely difficult download procedure without understanding what each character meant. Trust me, even a experienced person can get confused by the text ads.
I'm presenting a download in the attachment. When you run it, it suppose to run in English interface. If it doesn't, follow the pictures below to change language.

SmartRename features:

• Add, delete, replace and add numerical orders
• Rename file from a txt file
• Can rename item include directory, subdirectories and shortcuts
• Use the tags inside MP3/APE/WMA/RM/RMVB/RA/ASF/WMV/OGG to rename
• Chinese to Pinyin
• Preview Support
• Wildcard Support
• Regex Support
• Some built in variables
• Drag and Drop
• Undo
• Multilingual support
• Import and Export program logs
• Audio file tags to txt file
• Remove Audio file tags(humm.. why would I need this...)
• ID3v1 to ID3v2
• Change file dates
• CRC32 rename
• Right click menu

I am a Mathematica fan, after using it for months, the TI-83 plus can rarely feel the warmth of my hand1.
During school, or at friends house2, I have to deal with the life of Mathematicaless...
SpeQ come out of no where (well.. on stumble upon) and become part of my mathematical tool set!
First of all, SpeQ calculator's interface is command line like (btw, what is Microsoft thinking? calculator showing only one line of numbers?). Input and output, easily done.

Graphing, storing variables, add comments, declare functions and save the input+output are all possible.

The best of SpeQ is it's size! The main program is only 121KB, the help file is larger than the program, now I can take it everywhere, include my Journalism class, where the computers runs win 95/98 and the main portable storage device is floppy disks.
Did I tell you it's free?

1. 1. Replace "rarely" with "never" once Mathematica are allowed for all tests
2. 2. who does math at friend's house
