The UID format is associated with IBM Voice Type, IBM software for voice dictation and voice control on Microsoft Windows and IBM OS/2. It also allows users to control a computer by voice.
A .uid file contains user information used by Voice Type. It is a supporting data file rather than a document intended for direct editing or exchange.
Voice Type uses the file as part of its user data. The format is now a legacy format, so it is mainly encountered with older Voice Type installations.
Open a .uid file with IBM Voice Type on Microsoft Windows. The file is normally read by the software from its expected user-data folder rather than opened directly.
If Voice Type does not recognize the file, do not rename or edit it. Place it in the appropriate folder for the relevant Voice Type installation.
A .uid file cannot be meaningfully converted to another file format. It is an internal user-data file intended for IBM Voice Type, not a document or media file.
To retain the information, keep the original file with the associated Voice Type installation or back it up as-is.
