For example, ". When you create a long file name, Windows may also create a short 8. This 8. Not all file systems follow the tilde substitution convention, and systems can be configured to disable 8. Therefore, do not make the assumption that the 8. To request 8. This is true even if a long file name contains extended characters, regardless of the code page that is active during a disk read or write operation.
Files using long file names can be copied between NTFS file system partitions and Windows FAT file system partitions without losing any file name information. In this case, the short file name is substituted if possible.
The path to a specified file consists of one or more components , separated by a special character a backslash , with each component usually being a directory name or file name, but with some notable exceptions discussed below. It is often critical to the system's interpretation of a path what the beginning, or prefix , of the path looks like. This prefix determines the namespace the path is using, and additionally what special characters are used in which position within the path, including the last character.
Each component of a path will also be constrained by the maximum length specified for a particular file system. In general, these rules fall into two categories: short and long. Note that directory names are stored by the file system as a special type of file, but naming rules for files also apply to directory names. To summarize, a path is simply the string representation of the hierarchy between all of the directories that exist for a particular file or directory name.
For Windows API functions that manipulate files, file names can often be relative to the current directory, while some APIs require a fully qualified path. A file name is relative to the current directory if it does not begin with one of the following:.
If a file name begins with only a disk designator but not the backslash after the colon, it is interpreted as a relative path to the current directory on the drive with the specified letter. Note that the current directory may or may not be the root directory depending on what it was set to during the most recent "change directory" operation on that disk.
Examples of this format are as follows:. A path is also said to be relative if it contains "double-dots"; that is, two periods together in one component of the path. This special specifier is used to denote the directory above the current directory, otherwise known as the "parent directory". Relative paths can combine both example types, for example "C This is useful because, although the system keeps track of the current drive along with the current directory of that drive, it also keeps track of the current directories in each of the different drive letters if your system has more than one , regardless of which drive designator is set as the current drive.
In later versions of Windows, changing a registry key or using the Group Policy tool is required to remove the limit. See Maximum Path Length Limitation for full details. There are two main categories of namespace conventions used in the Windows APIs, commonly referred to as NT namespaces and the Win32 namespaces. The NT namespace was designed to be the lowest level namespace on which other subsystems and namespaces could exist, including the Win32 subsystem and, by extension, the Win32 namespaces.
Early versions of Windows also defined several predefined, or reserved, names for certain special devices such as communications serial and parallel ports and the default display console as part of what is now called the NT device namespace, and are still supported in current versions of Windows for backward compatibility. The Win32 namespace prefixing and conventions are summarized in this section and the following section, with descriptions of how they are used.
Quotes are used because path contains a space. For instance, if you create the above script as myrenamingscript. Open Powershell in windows and then type the following command after navigating to the folder where you want to rename the files. They are then piped to the next command with the operator. This replaces all instances of " " white space in this case this is the instance which is to be replaced with nothing, denoted by "", effectively wiping the word from all the files in the directory.
If you do not like the above method there is a awesome software named Bulk Rename Utility. I used this software personally and you can get many tuts on youtube how to use it.
The problem i have faced is that there is a possibility that there is already a file with the name you try to give to the new file eg if there are 2 files in the folder named "file one. So I made this script that checks if the new name already exists and if so places a number at the end of the file name adds 1 to the number until there is no other file with that name.
Instructions about what to change are at the top commended out lines. I hope this helps. Since programmatically renaming files is risky potentially destructive if you get it wrong , I would use a tool with a dry run mode built specifically for bulk renaming, e.
