Extract text from TerraIndex files (TI)
To convert TI files to another format, you need TerraIndex or other Data software.
To convert other file formats to the "Geotechnical Soil Data File" file type, you need software like TerraIndex or a similar tool.
The .ti file extension is highly ambiguous and heavily fragmented across multiple unrelated software ecosystems. Most prominently, it functions as a TerraIndex Project File used by geotechnical engineers to store soil investigation data. These engineering files are essentially standard ZIP archives housing structured project data. Alternatively, the .ti extension historically denotes a PlayStation TIM Image File developed by Sony Computer Entertainment for 3D console textures, a raw TIFF image, or a TomTom Traffic Incident Data File structured in plain JSON.
This extreme fragmentation makes handling .ti files incredibly frustrating. Opening them blindly usually results in error messages because operating systems do not know which application to launch. TerraIndex files require a proprietary and expensive enterprise license to view, trapping data away from non-engineering stakeholders. PlayStation TIM files are entirely obsolete, meaning default image viewers like Windows Photos or Apple Preview cannot render them. Likewise, TomTom telemetry logs lack native spreadsheet formatting.
To safely inspect or share these files, you must extract or convert them. For TerraIndex geotechnical files, convert or rename them to ZIP to extract the raw XML or database contents for archiving. If you have a legacy TIM or TIFF image, convert it to PNG for web compatibility or JPG for lightweight sharing. If your file contains TomTom traffic data, converting the underlying JSON structure to CSV is the best approach for data analysis in Microsoft Excel. Drag and drop your file to analyze and convert it - free, online, and without installing software.
Convert.Guru analyzes your TI file, detects the exact format, and lets you read the text inside.
Users also converted UCS, CIM and 20 files.
If you want to convert TI file to , you can use TerraIndex or similar software from the "Geotechnical Data or Image" category. In the File menu, look for Save As… or Export….
To convert files to TI, try TerraIndex or another comparable tool in the "Geotechnical Data or Image" category.
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 TI converter.
