If your Web site needs some speed or your photo collection takes up too much disk space, try Nuetools' StripFile . The program can shrink HTML and common Web image files (GIF, JPEG, and PNG) not by altering the content but by removing nonessential information such as color profiles and comments. Adjust the utility's Settings options to specify the kind of data it should remove. Or just point the program to a file or folder and click Compress .
For starters, this file manager uses tabs, making it easier to keep track of your files. ExplorerXP shows you folder size--not just file size--information, and it shows you the actual size of compressed files and folders. This program supports USB devices, so it's not a problem if you use an extra USB hard drive. It also lets you merge and split files and rename several files at once.
There are lots of programs that permanently delete files and recover them, but doesn't just having one on your hard drive make you look like you have something to hide? Restoration can rescue your accidentally deleted files and permanently delete the files you want good-and-gone. It can live on a floppy, so it leaves no trace of its activities.
WinSplit is a free utility that splits even 1GB files into e-mail or floppy-friendly bites, and re-joins the data into a single file at its destination. Three splitting options let you split the file by size, number of pieces, and at every instance of a particular word (when breaking up text files). There is also a feature that checks to ensure that all of the file pieces are an exact copy of the original. This application is free for personal use.
DoubleKiller hunts across single or multiple partitions and folders for identical files. It skips over files with important extensions like .dll, but it scans other files for duplicates. It checks the files' names, sizes, dates, and CRC32-checksums to see if any of them mirror one another. Once DoubleKiller locates the duplicates, it shows you a list of all of them so you can decide which ones to keep and which ones to delete or move.
