.tlb File Extension

Developer: Microsoft Corporation
File type: OLE Type Library
You're here because you have a file that has a file extension ending in .tlb. Files with the file extension .tlb can only be launched by certain applications. It's possible that .tlb files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .tlb file?

Files in the .tlb format are integrated with support for OLE technology. OLE or Microsoft Object Linking and Embedding is technology developed by Microsoft Corporation. User interface data is stored in these TLB files and are referenced by programs with OLE support when required. Visual Basic creates files in the .tlb format in instances where the developer selects "Remote Server Support File" in Visual Basic. These TLB files are also created if an ActiveX server or if an OLE server has been developed. Applications that can be used to open and view the content of these TLB files include Microsoft Excel 2010, and non-Microsoft Windows users can also open and view these TLB files using Microsoft Excel 2011 for Mac systems. Some users reported the stdole3.tlb file as a TLB file with malicious code that has Trojan virus functionality, so users are advised to leave this file alone and immediately do a system scan using an effective anti-virus application. Once this has been done and the anti-virus application has quarantined or healed the Microsoft Windows system, users are also advised to run a scan using an effective Microsoft System Registry cleaner software, since most Trojan viruses enter unnecessary entries into the Microsoft System Registry that cannot be removed by most anti-virus programs.

how to open a .tlb file?

Microsoft Office

Microsoft Office

Microsoft Office is an office suite of desktop applications, servers and services, released by Microsoft on August 1, 1989 for the Microsoft Windows and Mac OS X operating systems. Originally, the first version of Microsoft Office contained Microsoft Word, a word processor and was previously considered the main program in Office; Microsoft Excel, a spreadsheet program that originally competed with the dominant Lotus 1-2-3; and Microsoft PowerPoint, a popular presentation program for Windows and Mac.; a marketing term for a bundled set of applications. As years passed by, Office applications have grown significantly closer with shared features such as a common spell checker, Object Linking and Embedding (OLE) data integration and Microsoft Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. The current versions are Office 2010 for Windows, released on June 15, 2010; and Office 2011 for Mac OS X, released October 26, 2010.The new Office 2013 (version 15 of the Office suite) is reported to be released around December 2012.

a word of warning

Be careful not to rename the extension on .tlb files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .tlb. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
