## How It Works
50
+
51
+
CompactJV uses the Compact.exe tool from the Windows SDK to compress files. It supports several compression algorithms,
52
+
including XPRESS4K, XPRESS8K, XPRESS16K, XPRESS, and LZX.
53
+
54
+
Here's a brief overview of how each algorithm works:
55
+
56
+
1.**XPRESS4K**: This is a fast compression algorithm that provides a reasonable compression ratio. The '4K' in its name
57
+
refers to the size of the sliding window used during compression.
58
+
59
+
2.**XPRESS8K and XPRESS16K**: These are variations of the XPRESS4K algorithm. They use larger sliding windows of 8K and
60
+
16K, respectively. This allows them to achieve better compression ratios, but at the cost of slower performance.
61
+
62
+
3.**XPRESS**: This algorithm provides a balance between performance and compression ratio. It's more efficient than
63
+
XPRESS4K, XPRESS8K, and XPRESS16K, but not as powerful as LZX.
64
+
65
+
4.**LZX**: This is a very high-performance compression algorithm. It provides excellent compression ratios, but it's
66
+
also quite slow compared to the other algorithms.
67
+
68
+
When you choose to compress a file with CompactJV, the program uses one of these algorithms to reduce the file's size.
69
+
The specific algorithm used depends on the options you select.

## Usage
72
+
73
+
Here's how to use CompactJV:
74
+
75
+
1. Select the file you want to compress.
76
+
2. Choose the compression algorithm you want to use.
77
+
3. Click the 'Compress' button.
78
+
79
+
CompactJV will then compress the file using the selected algorithm. The compressed file will be saved in the same
80
+
location as the original file.
81
+
82
+
Remember: the more powerful the compression algorithm, the longer it will take to compress the file. If speed is a
83
+
concern, you may want to use a faster algorithm like XPRESS4K or XPRESS. If you're more concerned about reducing the
84
+
file's size as much as possible, you may want to use a more powerful algorithm like LZX.
