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.
The Picture Exchange file format, shortened PCX, with the .pcx filename extension is an image file format developed by ZSoft Corporation. It was initially released in 1985 as a lossless bitmap image format and for a time was the default file format for PC paintbrush. The format is now largely superseded by other formats given the target platforms for the software associated with the format are no longer in production, i.e. MS DOS and Windows 1.0.
FreeFileConvert uses tuned encoding for PDB to PCX conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PDB files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized PCX 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 PCX audio with dependable progress tracking.
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.
Later iterations of the format supported 24bit color palette, upgrading from the original 2 to 4 colors. Byte ordering used by the format is little endian ordering with three blocks; a 128 byte header, image data and an optional 256 color palette. Image data is stored in an orthoganal arrangement of scan lines ordered from the top to the bottom. Files can eiher be compressed using the simple RLE (Run Length Encoding) algorithm or uncompressed.
