TrID - stdin with the -@ switch.

It's possible to work on an entire folder tree, or a particular subset of files, just using the output of some other command through a pipe. Something like:

 	C:\TrID>dir d:\recovered_drive /s /b | trid -ce -@

 For /D /R j:\test %%1 IN (*) DO c:\trid_w32\trid "%%1"\* -ae


Replace j:\test with the directory that you want to move recursively through (TrID will not run on the files in the root of this directory).

Replace c:\trid_w32\trid with the path to trid.exe.

Dump the line in a batch file and run.

for /R /D %I IN (*.*) DO TRID "%I\*" ce

:: Wildcards can be used to scan groups of files, entire folders, etc. In addition, using the switch -ae will instruct TrID to add the guessed extensions to the filenames. This come handy, for example, when working with files recovered by data rescue softwares. For example:

 C:\TrID>trid c:\temp\* -ae

Instead, the switch -ce will just change the file extension to the new one; if the file has no extension, the new one will be added. For example:

  IAmASoundFile.dat -> IAmASoundFile.wav
  IAmABitmap -> IAmABitmap.bmp

It's possible to tell TrID to show some more information about every match (such as the mime type, who created that definition, how many files were scanned, etc.); and it's also possible to limit the number of results shown. The switch -v activate the verbose mode, and -r:nn specifies the max number of matches that TrID will display. Default is 5 for normal mode, 2 for verbose, 1 for multi-files analysis.
