The .tcr filename extension is a compressed text file format for eBooks and text associated with eBook reader software developed by Psion, a London based techonology company. The format has its beginnings in the early 90's and was designed for use on the PDAs released by the company, particularly the Series 3 handheld PDA. Though the format is proprietary and was intended for exclusive use on Psion devices, today, a few eBook reader applications can open files encoded in this format. As PDAs eventually lost there popularity, the format was discontinued when Psion eventually pulled out of the PDA market.
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 TCR to PDB conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload TCR 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 TCR format boasted of better compression of files saved in this format in comparison to its closest rival at the time, PalmDoc. The format is an adaptation of the ZVR text file viewer format developed for Psion, but incorporates the compression algorithms used in the TCReader program which was faster than that used on the ZVR format. The company claimed a 50% on average saving in memory storage after compression to TCR.
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.
