Technical Notes

How often should I wipe my free space?

Whenever you are concerned about what could potentially be in your free space, wipe your free space with ShredIt Android. In addition, you might want to consider running ShredIt Android on a regular, scheduled basis if that’s easier for you rather than trying to recall what you’ve had on your phone.

How long will it take to wipe the free space?

To wipe the free space on the device will take 1.35 minutes per gig for a one-pass overwrite.

To estimate how long the job will take, go into your Android settings to determine the available space on your Android device. (Settings > Device > Storage > Available space)

Then, multiply that by 1.35

  • For example, if you have 10 gb of Available storage, then it will take about 13-14 minutes to wipe the free space.
    10 x 1.35 = 13.5 minutes
  • For example, if you had done a Factory reset and then were wiping a 64 gb phone, in would take about an hour and ten minutes. (By comparison to do a Factory Reset on a 64gb phone will take less than 15 minutes.)

What if I do more than one pass?

Each pass will add to the time it takes to wipe the free space.

  • For example, if you have 10 gb of available storage and you were doing 5 passes, then it will take about 67-68 minutes to wipe the free space.
    i.e.  10 x 1.35 x 5 = 67.5 minutes
