File deletion is the removal of a file from a computer's file system. All operating systems include commands for deleting files (rm on Unix and Linux, [1] era in CP/M and DR-DOS, del/erase in MS-DOS/PC DOS, DR-DOS, Microsoft Windows etc.). File managers also provide a convenient way of deleting files. Files may be deleted one-by-one, or a whole ...
This essay, Deleting from Commons, is a reminder to (when appropriate) speedy delete images, videos, audios, or other files from Wikimedia Commons.Most images seen in English Wikipedia (or the other-language Wikipedias) are actually stored in the Commons project, with a link-through from the image name.
To securely delete the metadata of a PDF file, it is important to linearize the PDF file afterwards, otherwise changes are reversible and the metadata can be recovered. [5] [6] Metadata removal tools are also commonly used to reduce the overall sizes of files, particularly image files posted on the Web.
Choose carefully between group nominations (several file in the same deletion discussion) or multiple individual nominations. The former are more efficient for groups of cases that fall under exactly the same criteria, the latter for groups of cases that are different enough to require individual scrutiny.
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...
Quickly rendered animations can be saved directly as video files, but for high-quality rendering, individual frames (which may be rendered by different computers in a cluster or render farm and may take hours or even days to render) are output as separate files and combined later into a video clip.

This option provides a systematic compression scheme. Infrequently accessed files are compressed to free up disk space while leaving the frequently used files uncompressed for faster read/write access times. If after file compression, a user wishes to access a compressed file, the access times may be increased and vary from system to system.
When a file is "deleted" using a FAT file system, the directory entry remains almost unchanged except for the first character of the file name, preserving most of the "deleted" file's name, along with its time stamp, file length and — most importantly — its physical location on the disk.
