What is a TLB file?
A .TLB file is most often an OLE Type Library or COM Object Type Library created by Microsoft. Software developers use these files in Microsoft Visual Studio to store interface details about Component Object Model (COM) objects. This system allows different programming languages and software components to communicate with each other.
Because .TLB has multiple possible meanings, your file might not be a developer library. Some .TLB files are Transaction Log Backup files used by Intuit QuickBooks to protect accounting data. Historically, the .TLB extension also refers to the VAX/VMS Text Library format developed by Digital Equipment Corporation.
How to open TLB files?
To open a COM Type Library, developers typically use tools like the OLE/COM Object Viewer inside Microsoft Visual Studio or command-line utilities like `Tlbimp.exe`. If your file is a QuickBooks backup file, you must restore the data using the database recovery tools inside the accounting software.
