The .lit filename extension, short for literature, is a proprietary filename extension of the eBook file format LIT developed by Microsoft. The format was initially released in 2000 and at the time was only compatible with Microsoft Reader. Though DRM support was one of the strong selling points of the LIT format, wide spread DRM circumvention discounted its utility in favor for competing open formats. This among other reasons caused Microsoft to officially discontinue support for the format by 2011 and cease further sales of eBooks based on the format completely by 2012.
The .pdb filename extension refers to the program database file format authored by Microsoft. The format is used for storing debugging information about executable files and programming libraries or DLL files. The pdb format was designed to ease the debugging process of executables and program modules by decoupling the debugging information from the end of the program or class library itself to allow the integrated debugger and linker to access the pdb files directly. It doing so, the PDB format facilitates the stepping into/out of runtime libraries. The format and its internals remain the proprietary asset of Microsoft.
FreeFileConvert uses tuned encoding for LIT to PDB conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload LIT files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized PDB results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent PDB audio with dependable progress tracking.
The LIT format was extended from Microsoft's compiled HTML help format. The format includes support for digital rights management to enforce copyright material. This is however an optional feature. The format had no support for editing or exporting but in later years software programs were developed that allowed LIT files to be converted into formats that supported these features.
Within windows, when an application is debugged using the Microsoft suite of debugging tools, the program database file or .pdb file is used to determine the current execution state and to locate symbols within the applications source code. Typically, the pdb file will contain global/local variables, function names and their point of entry, frame pointer omission records, and source line numbers.
