Extract text from TIG files
To convert your TIG file to another format, you need TI Connect or other Backup software.
To convert other file formats to the "Calculator Group File" file type, you need software like TI Connect or a similar tool.
The .tig extension represents a frustrating collision of two distinct formats, often leaving users unsure of which software to launch.
Most commonly (37%), a .tig file is a TI Connect Backup File generated by Texas Instruments calculators (like the TI-83 or TI-84 Plus). These are proprietary binary containers used to bundle variables, applications, and settings for archiving purposes. You cannot simply "open" these in a text editor or view them in a browser; they are strictly designed to be restored to a physical calculator via the TI Connect software. Users often deal with issues here because modern operating systems lack native tools to inspect these backups, effectively locking the data away unless you have the specific legacy interface installed.
Alternatively (27%), a .tig file may be a TIFF Raw Image, sometimes associated with Telegram cache files or legacy imaging standards (TIFF/EP). In this context, the file is essentially a standard raster graphic that has been uniquely named. Users dealing with this variant often struggle with compatibility, as standard photo viewers may not recognize the extension despite the underlying structure being a valid image.

Users also converted TIF, PDF, JGW and MIG files.
If you want to convert TIG file to MIG, BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z or RAR, you can use TI Connect or similar software from the "Calculator Data Backup" category. In the File menu, look for Save As… or Export….

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our TIG converter.
