When installing Windows system, many users often distribute large disk space to system partition, for they are afraid the problem “low disk space” may happen to system partition. Also some people would like to make the whole hard drive only one big partition.

If system partition takes up too much space, that’ll be a waste of hard drive capacity. Also that takes too much time to look for desired program. What’s more, if you put system and other data together into one big partition, virus will attack all of them quickly at one time. Thus, an increasing number of users want to solve the problem without losing data.

It is not an easy job for Disk Management which can’t split partition directly. Users have to shrink one partition to get free disk space with this tool, and then create a new partition on the free space. What’s the easiest way of splitting a partition under Windows without data loss?

How to delete files permanently and ensure data security?

Updated on May 13th, 2021

When you are looking for ways of recovering lost files, have you ever spared one second to think about how to delete files permanently or make files unrecoverable? As we all know, files that are formatted or deleted by keys “Shift” and “Delete” can be recovered easily through certain skills. Therefore, it is really necessary to learn how to delete files permanently so that there is no possibility to get them back or threaten data security.

Advanced as data recovery technology is, we still have a way to make files unrecoverable as long as using a special tool. Here I’d like to choose PartitionGuru as an example to demonstrate the whole process.

PartitionGuru, mainly a piece of data recovery and disk management software, provides the function needed here. You may ask why the program has contradictory functions. That because both data recovery and delete data permanently comply the same theory. When you delete a file, the data is still on the hard drive instead of erased forever and operating system just mark the place taken by the deleted file as free so that other files can be written to there. Thus the deleted file can be recovered before a new file is written over. Thus to make files unrecoverable, PartitionGuru can just overwrites the files with random character at the same time it deletes files.

Method 1

After launching PartitionGuru, Right click the files you want to delete and select the item “Delete Files Permanently“.

Delete Files Permanently

You can appoint the characters that will be used to overwrite files.

Method 2

The first method will not be appropriate when you want to delete all the files of the whole partition or disk, and method 1 doesn’t work on files that have already been deleted or formatted.

Get the program started and select the partition or disk to be erased data. Then click items “Tools” and “Erase Sectors” in sequence and then you’ll get a dialog box to choose characters that are used to fill sectors.

When the operation is done, all the files on the partition or disk can never be recovered, and nobody will know what kind of data has been saved on the partition, and no one can recover those files by any means, either. So be aware when you carry out the operation.
