On macOS, it is possible to create an APFS formatted filesystem as either case-sensitive or case-preserving, with the default being case-preserving.
Reserved characters and words
On Windows, the following are reserved characters:
...
In addition, it is generally invalid to end a directory or file name with a space ' ' or period '.' character.
Do not use the following reserved names for the name of a file:
| No Format |
|---|
CON, PRN, AUX, NUL, COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, COM¹, COM², COM³, LPT0, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, LPT¹, LPT², and LPT³ |
Also avoid these names followed immediately by an extension; for example, NUL.txt and NUL.tar.gz are both equivalent to NUL.
On Linux filesystems, generally the only reserved character is slash '/', the same as on Mediaflux.
...
There are some other file names that may cause issues with certain software components within the Mediaflux stack. In particular, namespaces or assets that begin or end with a space can cause issues with some clients.
You can't make folders on the desktop that have "System Action" or "Device" references such as con, nul and prn. Solution is to use another name or use 0 instead of o,O for C0n.
Here are others :
CON, PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9,
LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9
