When you have a large number of files to compress into a single archive file, you may want to consider using the 'resize' tool. This is a very useful tool, however it should not be abused and if used in excess can lead to file corruption. In fact, some of the files that do not fit in the compressed file can end up corrupting it. Here we will look at the various ways to use the resize command in a secure manner to compress the data to disk.
The resize tool allows the files to be edited or read while the files are being resized. It does not require a full new file block, with an exact size equal to the new resulpto. Instead, it allocates a new block, which is just as big as the difference in the original and new results, and maps that block onto the existing block. If you want to get the full benefits of the resize function, you must run the resize function again after the data has been mapped, but before the data has been compressed.
The most important thing about the resize option is to make sure that you can restore the original size to the file when the resize operation is complete. Most tools offer a 'restore size' feature, which allows you to restore the file size to that which was originally stored. However, there are tools that do not allow for this restore feature and you must rely on using the resize function to restore the file size. This is because if the size you initially saved to the file was larger than the amount that the program is capable of restoring, you could end up corrupting the file, and the only way to save the file would be by resetting the size. So, make sure you make a backup first to ensure that you are safe.
