If the files has been deleted, there's still a chance that the data is still there, but has just been set to be overwritten by new data. By not accessing the SD card, you increase the chances that the data will not be overwritten. Until you're ready to try recovering files, it's best to remove the SD card from any device. The full version of ZAR requires a purchase, but the demo version allows you to recover image files only. Only download ZAR from the developer's website. On the ZAR website, click the "image recovery" link towards the bottom of the page. This will allow you to install the free demo that can recover images. Insert your SD card into your computer using an SD card reader, or by putting it in your camera and connecting the camera via USB. Your computer may prompt you to format your card or say that it's not readable. Do not format your card according to this prompt, as this can write over where your pictures are saved on the card. Start ZAR and click Image Recovery (Free). In other programs, look for a similar button. Some programs may skip this step altogether. In the "Disks and partitions", select your SD card. It should be labeled as an SD card. Click Next to start the recovery scan. You will see a list of images that the software found on your SD card. Select the images that you want to recover, or select all to restore all the lost images. You may not be able to preview them, and the filenames will most likely be lost. If your SD card has been damaged, don't save them to the card. Instead, choose or create a folder on your computer to save the pictures to. This will keep your pictures safe if anything happens to your SD card again. Click Start copying the selected files to restore the pictures. The files selected file will be saved to the location you specified. Some pictures may not be able to be fully restored. Even if the thumbnail looks okay, the picture itself may be partially or fully damaged.

Summary: Stop accessing the SD card. Download and install ZAR (Zero Assumption Recovery). Insert your SD card. Open the Image Recovery tool in ZAR. Select your SD card. Choose which files you want to recover. Choose where to store the recovered images. Copy the files.

Different parts of the book will require their own cleaning methods. You'll want multiple tools on hand to address any potential problems your book may have. An artgum eraser is the perfect object for removing small pencil marks, smudges, and medium-sized blemishes on the pages. A soft cloth such as cut-up white t-shirt works well for gently cleaning surface dirt. You can also try an electrostatic cloth for an option that both lifts and holds dirt. You'll need a small, soft brush, such as a toothbrush, to clean bindings and page edges. If your book is extremely dirty or dusty, you might need to vacuum the surface. You'll need a vacuum with a low-suction setting and a soft-brush attachment. A document cleaning pad, which is a sieved cloth filled with eraser dust, will help remove a layering of dust from the pages, as well as smudges from matte dust jackets. You'll need a few different supplies to deal with your book's various components and unique trouble spots. Be sure to have access to petroleum jelly, a book cleaner putty, absorbent paper towels, and baking soda. Once you've collected all your supplies, set them up in a well-lit, comfortable work area. You'll want plenty of space to spread out in an area you don't mind getting a bit dirty.

Summary: Gather a variety of cleaning implements. Assemble the necessary cleaning solutions. Choose an appropriate spot for cleaning.

Wooden floors should have an additional layer of wax added once every six to twelve months. Vinyl floors should be waxed every six months, as should sealed ceramic or stone floors. The wax seal is not watertight, so the water could damage the wood. Wipe up spills with a damp paper towel instead. Vinyl and other non-wood surfaces can be cleaned with a damp mop, not a soaking one. This does not apply to wood treated with polyurethane, which can be mopped with a mop dampened by a mixture of one quart (1 liter) water and 1/4 cup (60 mL) vinegar. Use a terry cloth or buffing pad to polish the floor if it begins to get dull. This shouldn't be necessary for no-buff wax. If you don't want to do this manually, use a floor machine with a light scrubbing pad just strong enough to remove a small portion of the wax. You should apply a new layer or two of wax after removing some to create a strong protective layer again. This should not be required for several years at least if your floor was waxed properly.
Summary: Reapply wax to the floors regularly. Don't use a soaking mop, and never mop waxed hardwood. Buff or polish the floor if the shine fades. Sand or scrub off part of the wax if it becomes yellowed or discolored.
