Free reduce file size software for windows

ReducePhotoSize reduces the size of a digital photo by halving or quartering the resolution and/or by reducing the jpeg quality to any percentage.
ReducePhotoSize is a useful photo shrinking utility that will come in handy.

Duplicate File Hard Linker is a small command line tool to reduce the size of duplicate files on one partition Duplicate File Hard Linker is a small command line tool to reduce the size of duplicate files on one partition.
Unlike all other known tools in this application the files are not being listed, archived or removed but going to be hard-linked using NTFS hard links. The tool runs in Windows NT 4.0 / 2000 / XP and 2003 Server and requires a NTFS file system to run on.
Main features:
- Command line Tool for Windows NT4.0/2000/XP/2003
- Links duplicate files in file system using NTFS "Hard Link" facility. For further information please take a look to Website at Microsoft.
- Runs recursive through a tree of folders on one partition
- Compares all files byte-per-byte to ensure really only equal files to be hard linked
- Check-Mode (default) allows listing of all optimization possibilities. In this mode no changes will be done.
- Additional options allow control of which parameters of files will be compared, to check attributes and time stamps of files
- All read/compare operations were optimized for maximum performance and will reach almost the maximum throughput of the physical disk. The system will be loaded only in background.
- File system short named (8.3 Names) can be lost during hard linking. This can lead to problems with programs requiring 8.3 names.

Small freeware program for WIN 95. Shows drives used, free and total space in bytes, Kb & Mb.

The easy-to-use tool for reducing and optimizing 3D models. Decimates the number of polygons, in result reduces 3D file size and increases 3D rendering performance. Utilise existing CAD-data to 3D product presentations or to virtual training scenarious. Evaluate different LODs and freely rotate the the model together as well zoom in on specific details. Supports VRML format.
From our customers:
Ive tried out several commercial polygon reduction tools in the past, and this is easily as good or better than them. Its extremely simple to use and the polygon reduction is great. Very useful for simplifying models made with nurbs or metaballs. It reduced a high-poly vrml model from 617kb to 115kb with practically no difference in appearance. I had to check the wireframe view to be sure of what I was seeing lol. Congrats on a cool tool :)

"Great program, and best of all free." While only supporting one format and you can not view your model with the program. It is still awseome! The reduction methods are great and high poly models when reduced, arnt butchered and can signifitly reduce the polycount with out major quality reduction. Cheers to the developers for this great program (and making it free ;)) mus have for any modeler.

We are right now using XXX (one very expensive reduction tool) and I tested your software and it worked good. In some case better (preserved more details) and in some case a little bit worse. But in total I was very impressed. We want to use CAD files and we all know how much work it is to opimize CAD for real-time. Since there are a wide range of different CAD formats we have to select a format that everybody can export to and I guess that is VRML or maybe stl.
