Do files with an extension, '.tmp' clutter your computer memory? Have you often been advised to clear the temporary files for increased browser performance? That means you have some experience working with temporary files!
What are They?
When a computer program is unable to allocate sufficient memory for its tasks or when a program has to work on data larger than the address space provided by the system architecture, temporary files are created. Their creation by a computer program may also be the result of some form of inter-process communication.
They may be created as backups. Applications like Microsoft Office create a temporary version of a file that is being worked on. If the program crashes or the computer shuts down, the temporary file can be of use as the recently saved version of the file. If the program closes normally, the temporary file is deleted.
Where are They Located?
Typically, they are located in the temporary directory /tmp on Unix machines. On Windows machines, they are located on %TEMP%.
Temporary files can be removed manually by going to their location and deleting them. One can search for tmp files on a computer and delete them. The other option is to go to Start, Run, type in %temp%, thus landing in the folder where all temporary files are stored, which can then be deleted (individually or all at once). As a part of the reboot process of a computer, temporary files are deleted.
In case one is unable to delete a certain temporary file, it indicates that a program using that temporary file is running in the background. In that case, all programs need to be closed before the temporary files can be deleted.
Temporary Internet Files
The Internet browser cache consists of temporary Internet files. The files that are downloaded with web pages are stored as temporary Internet files. Thereby, a cache of the web pages visited, is created on the computer hard disk. They remain there until the user deletes them manually.
A browser creates temporary Internet files to store web site data for the web pages visited. When web page files are sent to the browser, they are stored so that they can be retrieved the next time that web page is visited. The next time the same web page is visited, the data is taken from the temporary file. This helps the browser display web pages faster. They are stored in the Temporary Internet Files directory and comprise java scripts, style sheets, cookies, etc.
Temporary Internet files are removed as a part of the Disk Cleanup process. The Internet options of browsers allow users to change/adjust browser settings such that temporary Internet files are deleted each time the browser is closed. To delete temporary Internet files in Chrome, one needs to open Tools, select Options, click on Clear Browsing Data, and check the Empty the cache checkbox. In Internet Explorer, one needs to tick the Temporary Internet Files checkbox in Tools and click on Delete. In Firefox, one needs to go to Tools, click on Clear Recent History, click on Details, select Cache and click on Clear now.
These files give rise to Internet privacy issues, as it is due to these files that the pages visited by a user remain available to the other users using the same local computer for Internet access. They also consume a fair amount computer memory. But they can be useful in certain ways. Cached websites are available offline, thanks to temporary Internet files. These files help a computer maintain records of the websites visited.
