File Names Seem to Be Limited to Less Than 255 Characters

Symptoms

You may experience one or both of the following symptoms when you
attempt to create a file in Windows 95:
When you attempt to use Windows Explorer or another program to create
a file in a folder other than the root folder of a drive, the length
of the file name seems to be limited to less than 255 characters. If
you use Windows Explorer to move or copy a file with a very long file
name to a folder other than the root folder of a drive, you may
receive the following error message:
Cannot copy <file name>. The file name you specified is invalid or too
long. Specify a different filename.
When you attempt to use Windows Explorer to create a file in the root
folder of a drive, the length of the file name seems to be limited to
250 characters.
These symptoms occur even though the Windows 95 documentation states
that a file name in Windows 95 can include up to 255 characters.

Cause

Long file names are limited to 255 characters in Windows 95. However,
the maximum path length in Windows 95 is 259 characters. The maximum
path length represents the length of the file name, plus the number of
characters used to represent the drive and folder where the file is
located. For example, the path length for the file C:\Windows
\LongFileName.extension is 33 characters, but the file name is only
22 characters.

Because the path length is limited to 259 characters, a long file name
is limited to less than 255 characters if more than five characters
are needed to represent the drive and folder where the file is
located. If five characters or less are needed to represent the drive
and folder where the file is located, the long file name is limited to
255 characters, even if the total path length is less than 259
characters. For example, if a file is located in the root folder of a
drive, the long file name is still limited to 255 characters, even
though 256 characters could be used before the maximum path length is
reached.

When you use Windows Explorer to create a file, the length of the file
name is limited to 250 characters instead of 255 characters. This is a
known problem that occurs with Windows Explorer in Windows 95.
However, if you use another program to create a file with a file name
longer than 250 characters, the entire file name is visible in Windows
Explorer.
