Unknown file
Date updated: October 4, 2026
The contents and purpose of a .tb_ file cannot be determined from the extension alone. No confirmed vendor, software package, or standard format is identified for this record.
The file may be application-specific, renamed, incomplete, or created by software that uses a private file naming scheme. Its format can only be established by examining the file's source and contents.
There is no confirmed program that opens the .tb_ file format. The software that created the file is the most likely program to recognize it.
Do not rename the file to a different extension unless the creating software or a reliable source confirms that the change is appropriate.
A .tb_ file cannot be converted reliably until its format and creating software have been identified. There is no confirmed converter for this unidentified file type.
