Temp folder is on a drive that is full or is inaccessible

Are you confused at why your computer is showing the error “the temp folder is on a drive that is full or is inaccessible”?


Temp folder or temporary folder is a directory used to hold temporary files. Some software programs and operating systems automatically delete the files in the temp directory at regular intervals. For security reasons, it is better for each user to have their own temporary directory because there has been a record of security vulnerabilities with temporary files. The general procedure for system administration is to decrease the amount of storage space used on the computer by deleting the temporary files. But, in case of multi-user systems, it can remove active files as well thereby creating problems. For avoiding this, it is better to remove only files that are inactive for several days. The temp folder can create problems in the installation process of some programs like Adobe® Reader® 8.
