Any variation of upper and lower case can be used to refer to the same file. POSIX Programmer's Guide: Writing Portable UNIX Programs 1991 O'Reilly & Associates, Inc. Nonetheless, some limited interoperability issues remain, such as normalization (equivalence), or the Unicode version in use. This can be solved at the application level, with some tricky normalization calls. The issue of Unicode equivalence is known as "normalized-name collision". Check This Out
Paths are only normalized for the purpose of comparisons. Marks any sequence of characters (Unix, Windows, DOS) or any sequence of characters in either the basename or extension (thus "*.*" in DOS means "all files". However, modern Unix-like systems support long file names, usually up to 255 bytes in length. Please help improve this article by adding citations to reliable sources.

Edit: if that's the reason you're asking, in program source I would still use Filename for a class or filename for a variable, not FileName nor fileName, respectively. For instance, UDF is limited to Unicode 2.0; macOS applies NFD Unicode normalization and is optionally case-sensitive (case-insensitive by default.) Filename maximum length is not standard and might depend on the
Multiple output files created by an application use the same basename and various extensions. Filename Extension Definition Wiki.winehq.org. This is somewhat analogous to the domain names that are used on the Internet to identify web sites. Conversion was not possible as most systems did not expose a description of the encoding used for a filename as part of the extended file information.
Before Unicode became a de facto standard, file systems mostly used a locale-dependent character set. Explain File Renaming a file at Commons might affect 500+ projects instead of just one. What files should not be renamed? Shortcut: WP:FMNN As a matter of principle, it is best to leave all files with generally valid names at their locations, even if slightly better August 26, 2013.

Filename Or File Name One example is .rpm, used for both RPM Package Manager packages and RealPlayer Media files; others being .qif, shared by DESQview fonts, Quicken financial ledgers, and QuickTime pictures, and .gba, shared Filename Example Many Windows applications are limited to a MAX_PATH value of 260, but Windows file names can easily exceed this limit .
space Allowed, but the space is also used as a parameter separator in command line applications. his comment is here Other filesystems, by design, provide only one filename per file, which guarantees that alteration of one filename's file does not alter the other filename's file. Improvements The filename extension was originally used to easily determine the file's generic type. The need to condense a file's type into three characters frequently led to inscrutable extensions.

Partitioned data sets (PDS or PDSE) are divided into members with names of up to 8 characters; the member name is placed in parenthesises after this contact form This also became a problem for programmers experimenting with the Java programming language, since it requires source code files to have the four-letter suffix .java and compiles object code output files
This can be solved by quoting the entire filename. List Of Filenames Any variation of upper and lower case can be used to refer to the same file. Should I be using "file name" or "filename" in my writing?

Some systems will adopt their own standardised nomenclature like "path name", but these too are not standardised across systems. You can help by adding to it. (July 2012) Around 1962, the Compatible Time-Sharing System introduced the concept of a file (i.e. Filename Definition File:Ninja.jpg File:NINJA.jpg Also File:Bunny.jpg File:Bunny.jpeg File:Bunny.JPEG File:Ninja_1.jpg File:Ninja_2.jpg Also File:Bunny_1.jpg File:Bunny_2.jpg File:Bunny_3.jpg WP:FNC#7 8 Remove pejorative, offensive or crude language that would not be appropriate in the file description File:Stupid fat

This is given in a line of text preceding the stream, such as Content-type: text/plain. Support.apple.com. Workarounds include appending a dot when renaming the file (that is then automatically removed afterwards), using alternative file managers, or saving a file with the desired filename from within an application. When that happens, you can combine the two, though it's not advisable for formal usage.
