For Loop in DOS Batch File

FOR %%c in (C:\Windows\*.*) DO (echo file %%c)
You can implement a FOR loop to act on one or more files returned from the IN clause. We originally found this in order to GPG decrypt a file using wildcards (where you don't know exactly the entire file name, i.e.: Test_File_??????.txt, where ?????? = the current time in HHMMSS format). Since we won't know the time the file was generated, we need to use wildcards. And as a result of GPG not handling wildcards, this is the perfect solution. Thought I would share this revelation. :-)
Sample Output
file C:\Windows\bfsvc.exe
file C:\Windows\bootstat.dat
file C:\Windows\DtcInstall.log
file C:\Windows\EnterpriseN.xml
file C:\Windows\explorer.exe
file C:\Windows\fveupdate.exe
file C:\Windows\HelpPane.exe
file C:\Windows\hh.exe
file C:\Windows\HPMProp.INI
file C:\Windows\IE9_main.log
file C:\Windows\iis7.log
file C:\Windows\ISMIF32.dll
