I'm trying to use robocopy to transfer a single file from one location to another but robocopy seems to think I'm always specifying a folder. Here is an example:. According ohw the Wikipedia article on Robocopy :. Robocopy syntax is markedly different from standard copy commands, as it accepts only folder names as its source and destination arguments.
Files may be selected ttansfer excluded using the optional filespec filtering argument. Filespecs can only refer to the filenames relative to the folders already selected for copying. Fully-qualified path names are not supported. For example, in order to copy the file foo. Sign up to join this community. The best answers are voted up and rise to the top.

I expect it's a text escaping thing — Mike Goatly Oct 23 '15 at MikeGoatly Excellent point. It wants you to name the directories as "names" and does not how to make a curved sidewalk to imply in any way that it accepts anything other than a directory. According to the Wikipedia article on Robocopy : Folder copier, not file copier Robocopy syntax is markedly different from standard copy commands, as it accepts only folder names as its source and destination arguments.
One thing I noticed. It will recreate all the folders with no files in them. I guess since the foo. Thats why the empty folders are created. HBruijn 68k 20 20 gold badges silver badges bronze badges.

Mar 12, · 3 Ways to Transfer Microsoft Office To New/Another Computer. When you get a new computer and plan to replace your old one, you may want to transfer Microsoft Office to another computer. Unlike data transfer, moving programs to a new computer is a little bit difficult because of the activation problem.
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital,  largely replacing those that capture images on photographic film.
While there are still dedicated digital cameras, many more cameras are now incorporated into mobile devices like smartphones , which can, among many other purposes, use their cameras to initiate live video-telephony and directly edit and upload images to others. Digital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.
However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing. Atalla and Dawon Kahng at Bell Labs in Boyle and George E.
In the s, Eugene F. Lally of the Jet Propulsion Laboratory was thinking about how to use a mosaic photosensor to capture digital images. His idea was to take pictures of the planets and stars while travelling through space to give information about the astronauts' position.
The Cromemco Cyclops was an all-digital camera introduced as a commercial product in Its design was published as a hobbyist construction project in the February issue of Popular Electronics magazine.
Steven Sasson , an engineer at Eastman Kodak , invented and built a self-contained electronic camera that used a charge-coupled device CCD image sensor in Practical digital cameras were enabled by advances in data compression , due to the impractically high memory and bandwidth requirements of uncompressed images and video. Nikon was interested in digital photography since the mids.
In , while presenting to Photokina , Nikon introduced an operational prototype of the first SLR-type electronic camera Still Video Camera , manufactured by Panasonic.
The camera's memory card had a capacity of 2 MB of SRAM static random-access memory , and could hold up to ten photographs. However, it could not send the resulting image over the telephone function, but required a computer connection to access photos.
By the beginning of the s, almost all smartphones had an integrated digital camera. The image processing capabilities of the camera determine the outcome of the final image quality much more than the sensor type.
The resolution of a digital camera is often limited by the image sensor that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel.
Depending on the physical structure of the sensor, a color filter array may be used, which requires demosaicing to recreate a full-color image. The number of pixels in the sensor determines the camera's " pixel count ". In a typical sensor, the pixel count is the product of the number of rows and the number of columns. For example, a 1, by 1, pixel sensor would have 1,, pixels, or 1 megapixel. Firmwares' resolution selector allows the user to optionally lower the resolution, to reduce the file size per picture and extend lossless digital zooming.
A lower resolution extends the number of remaining photos in free space, postponing the exhaustion of space storage, which is of use where no further data storage device is available, and for captures of lower significance, where the benefit from less space storage consumption outweighs the disadvantage from reduced detail. The final quality of an image depends on all optical transformations in the chain of producing the image.
In the case of the digital camera, a simple way to describe this concept is that the lens determines the maximum sharpness of the image while the image sensor determines the maximum resolution.
The illustration on the right can be said to compare a lens with very poor sharpness on a camera with high resolution, to a lens with good sharpness on a camera with lower resolution. Since the first digital backs were introduced, there have been three main methods of capturing the image, each based on the hardware configuration of the sensor and color filters.
Single-shot capture systems use either one sensor chip with a Bayer filter mosaic, or three separate image sensors one each for the primary additive colors red, green, and blue which are exposed to the same image via a beam splitter see Three-CCD camera.
Multi-shot exposes the sensor to the image in a sequence of three or more openings of the lens aperture. There are several methods of application of the multi-shot technique. The most common was originally to use a single image sensor with three filters passed in front of the sensor in sequence to obtain the additive color information. Another multiple shot method is called Microscanning. This method uses a single sensor chip with a Bayer filter and physically moves the sensor on the focus plane of the lens to construct a higher resolution image than the native resolution of the chip.
A third version combines these two methods without a Bayer filter on the chip. The third method is called scanning because the sensor moves across the focal plane much like the sensor of an image scanner. The linear or tri-linear sensors in scanning cameras utilize only a single line of photosensors, or three lines for the three colors. Scanning may be accomplished by moving the sensor for example, when using color co-site sampling or by rotating the whole camera.
A digital rotating line camera offers images consisting of a total resolution that is very high. The choice of method for a given capture is determined largely by the subject matter. It is usually inappropriate to attempt to capture a subject that moves with anything but a single-shot system. However, the higher color fidelity and larger file sizes and resolutions that are available with multi-shot and scanning backs make them more attractive for commercial photographers who are working with stationary subjects and large-format photographs.
Improvements in single-shot cameras and image file processing at the beginning of the 21st century made single shot cameras almost completely dominant, even in high-end commercial photography. Most current [ timeframe? A demosaicing algorithm is used to interpolate color information to create a full array of RGB image data.
Cameras that use a beam-splitter single-shot 3CCD approach, three-filter multi-shot approach, color co-site sampling or Foveon X3 sensor do not use anti-aliasing filters, nor demosaicing. Firmware in the camera, or a software in a raw converter program such as Adobe Camera Raw , interprets the raw data from the sensor to obtain a full color image, because the RGB color model requires three intensity values for each pixel: one each for the red, green, and blue other color models, when used, also require three or more values per pixel.
A single sensor element cannot simultaneously record these three intensities, and so a color filter array CFA must be used to selectively filter a particular color for each pixel. The Bayer filter pattern is a repeating 2x2 mosaic pattern of light filters, with green ones at opposite corners and red and blue in the other two positions. The high proportion of green takes advantage of properties of the human visual system, which determines brightness mostly from green and is far more sensitive to brightness than to hue or saturation.
Sometimes a 4-color filter pattern is used, often involving two different hues of green. This provides potentially more accurate color, but requires a slightly more complicated interpolation process. The color intensity values not captured for each pixel can be interpolated from the values of adjacent pixels which represent the color being calculated.
Cameras with digital image sensors that are smaller than the typical 35 mm film size have a smaller field or angle of view when used with a lens of the same focal length. This is because angle of view is a function of both focal length and the sensor or film size used. The crop factor is relative to the 35mm film format. If a smaller sensor is used, as in most digicams, the field of view is cropped by the sensor to smaller than the 35 mm full-frame format's field of view.
This narrowing of the field of view may be described as crop factor, a factor by which a longer focal length lens would be needed to get the same field of view on a 35 mm film camera. Full-frame digital SLRs utilize a sensor of the same size as a frame of 35 mm film. Common values for field of view crop in DSLRs using active pixel sensors include 1. Crop factors for non-SLR consumer compact and bridge cameras are larger, frequently 4x or more.
Digital cameras come in a wide range of sizes, prices and capabilities. In addition to general purpose digital cameras, specialized cameras including multispectral imaging equipment and astrographs are used for scientific, military, medical and other special purposes. Compact cameras are intended to be portable pocketable and are particularly suitable for casual " snapshots ". Many incorporate a retractable lens assembly that provides optical zoom.
In most models, an auto actuating lens cover protects the lens from elements. Most ruggedized or water-resistant models do not retract, and most with superzoom capability do not retract fully. Compact cameras are usually designed to be easy to use. Almost all include an automatic mode, or "auto mode", which automatically makes all camera settings for the user.
Some also have manual controls. Compact digital cameras typically contain a small sensor which trades-off picture quality for compactness and simplicity; images can usually only be stored using lossy compression JPEG.
Most have a built-in flash usually of low power, sufficient for nearby subjects. A few high end compact digital cameras have a hotshoe for connecting to an external flash.
Live preview is almost always used to frame the photo on an integrated LCD. In addition to being able to take still photographs almost all compact cameras have the ability to record video. Compacts often have macro capability and zoom lenses , but the zoom range up to 30x is generally enough for candid photography but less than is available on bridge cameras more than 60x , or the interchangeable lenses of DSLR cameras available at a much higher cost.
Some compact digital cameras use a hybrid autofocus system similar to what is commonly available on DSLRs. Typically, compact digital cameras incorporate a nearly silent leaf shutter into the lens but play a simulated camera sound for skeuomorphic purposes.
For low cost and small size, these cameras typically use image sensor formats with a diagonal between 6 and 11 mm, corresponding to a crop factor between 7 and 4.
This gives them weaker low-light performance, greater depth of field , generally closer focusing ability, and smaller components than cameras using larger sensors. A variety of additional features are available depending on the model of the camera. Such features include GPS , compass, barometers and altimeters. Starting in , some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos with dual lens or even single lens for play back on a 3D TV.
In , Sony released two add-on camera models without display, to be used with a smartphone or tablet, controlled by a mobile application via WiFi. Rugged compact cameras typically include protection against submersion, hot and cold conditions, shock and pressure. Terms used to describe such properties include waterproof, freezeproof, heatproof, shockproof and crushproof, respectively.
Nearly all major camera manufacturers have at least one product in this category. Some are waterproof to a considerable depth up to 82 feet 27 m ; [ citation needed ] others only 10 feet 3 m , but only a few will float. Ruggeds often lack some of the features of ordinary compact camera, but they have video capability and the majority can record sound.
Most have image stabilization and built-in flash. GoPro and other brands offer action cameras which are rugged, small and can be easily attached to helmet , arm, bicycle, etc. Most have wide angle and fixed focus, and can take still pictures and video, typically with sound.
