Spring Cleaning On Your Hard Drives
Some files and folders are just too stubborn to delete easily. Try these tips.
Why am I unable to delete a file or a folder in Windows Explorer? What
are some of the common scenarios and solutions?
A: As far as NTFS is concerned, internally it treats folders as a special type of file. Therefore, we will use the term "file" to refer to both
files and folders here.
There are many possible reasons why you may not be able to delete a
file. For example, if you don't have proper permissions, you will get
an "access denied" error. To delete files, you will need to log on
as an Administrator, take ownership of the files and give yourself
permissions to delete the files before deleting them.
Under certain situations, you may not be able to delete the files in
Windows Explorer, even if you take the ownership. For example, if the
access control entries in an Access Control List (ACL) has a certain
sequence, it may prevent you from deleting the files. In such cases,
use CACLS.EXE at the command prompt to overwrite the existing ACLs.
Sometimes the problem may be too simple. For example, you cannot
delete a file that's open. Simply close the file and then delete it.
If the file is corrupted, you may not be able to delete it. Use
CHKDSK with /F switch to fix the problems and then try to delete
Sometimes, the file path is too long to get to it. Typically, the
path length must not exceed 255 characters. In these situations,
use the 8.3 filename to access and delete the file. In some cases you
may have to rename some of the folders to shorten the path.
