TrID - File Identifier

TrID is an utility designed to identify file types from their binary signatures. While there are similar utilities with hard coded logic, TrID has no fixed rules. Instead, it's extensible and can be trained to recognize new formats in a fast and automatic way.

TrID has many uses: identify what kind of file was sent to you via e-mail, aid in forensic analysis, support in file recovery, etc.

TrID uses a database of definitions which describe recurring patterns for supported file types. As this is subject to very frequent update, it's made available as a separate package. Just download both TrID and this archive and unpack in the same folder.

The database of definitions is constantly expanding; the more that are available, the more accurate an analysis of an unknown file can be. You can help! Use the program to both recognize unknown file types and develop new definitions that can be added to the library. See the TrIDScan page for information about how you can help. Just run the TrIDScan module against a number of files of a given type. The program will do the rest.

Because TrID uses an expandable database it will never be out of date. As new file types become available you can run the scan module against them and help keep the program up to date. Other people around the world will be doing the same thing making the database a dynamic and living thing. If you have special file formats that only you use, you can also add them to your local database, making their identification easier.

To get you started, the current library of definitions is up to 21323 file types and growing fast.

TrID is simple to use. Just run TrID and point it to the file to be analyzed. The file will be read and compared with the definitions in the database. Results are presented in order of highest probability.

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 TrID - File Identifier v2.48 - (C) 2003-2026 By M.Pontello Loading definitions from file: triddefs.trd (Reading from cache...) Definitions found: 20046 Analyzing... File: c:\temp\FILE0001.CHK 75.8% (.BAV) The Bat!

At this point, the files in the c:\temp folder will look like:

  FILE0001.CHK.bav
  FILE0002.CHK.ogg
  FILE0003.CHK.doc
  FILE0004.CHK.exe

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

TrID can get a file list from a file, with the -f switch.
So it's possible to work on an entire folder tree, or a particular subset of files, just using a list built with some or other tool. Something like:

C:\TrID>trid -f d:\recovered_drive\filelist.txt TrID - File Identifier v2.48 - (C) 2003-2026 By M.Pontello Loading definitions from file: triddefs.trd (Reading from cache...) Definitions found: 20046 Analyzing... File: d:\recovered_drive\notes 100.0% (.RTF) Rich Text Format (5000/1) File: d:\recovered_drive\temp\FILE0001.CHK 77.8% (.OGG) OGG Vorbis Audio (14014/3) ...

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 -n num specifies the max number of matches that TrID will display (default is 5).

c:\TrID>trid "\t\Windows XP Startup.ogg" -v -n 2 TrID - File Identifier v2.48 - (C) 2003-2026 By M.Pontello Loading definitions from file: triddefs.trd (Reading from cache...) Definitions found: 20046 Analyzing...

When starting, TrID will check for the TrIDDefs.TRD definitions package in the current directory. If not found, it will search on the some folder where TrID is installed. Eventually, it's possible to specify a particular defs file with the switch -d filespec. To force TrID to wait for a key after showing the results, the -w switch is provided.

To speed up the process of getting the latest updated definitions, it's possible to use the --update switch (or the TrIDUpdate Python script, for older versions). It first compare the MD5 digest of the current TRD file and the one available online, so if the file isn't changed it's very quick. For example:

c:\TrID>trid --update TrID - File Identifier v2.48 - (C) 2003-2026 By M.Pontello TrID defs package triddefs.trd - Checking for updates... File triddefs.trd not found Checking last version online...

OK. c:\TrID>trid --update TrID - File Identifier v2.48 - (C) 2003-2026 By M.Pontello TrID defs package triddefs.trd - Checking for updates... MD5: 27750cda2cb5addb7e687b923da49b81 Checking last version online... MD5: 27750cda2cb5addb7e687b923da49b81 Current defs are up-to-date.

It's also possible to create a CSV file with the results, ready to be parsed by another app, imported in a spreadsheet, etc:

c:\TrID>trid files\* --out results.csv TrID - File Identifier v2.48 - (C) 2003-2026 By M.Pontello Loading definitions from file: triddefs.trd (Reading from cache...)
