When you add a new file to a Perforce depot, Perforce stores its contents according to its type. In addition, Perforce uses a file's type to determine how it gets written into a client workspace.
A Perforce filetype consists of a base type (text, binary, etc.) plus modifiers (uncompressed, writeable, etc.). You specify a Perforce filetype as base+modifier(s). For example:
text+kxis an executable text file with keyword expansion. Its base type is "text"; its modifiers are "keyword expansion" and "executable". Use this format when changing filetypes. You can also use this format when opening files for add, edit, or integrate, to override the default filetype.
| Type | Client workspace appearance | Perforce server storage |
|---|---|---|
| text | Text | Text; reverse-delta (RCS) format |
| binary | Raw bytes | One file per revision; compressed |
| symlink | Symbolic link on Unix; text on other platforms | Text; content is name of linked file |
| resource | Unicode file | Stored as UTF-8 |
| apple | Mac resource + data | One file per revision; compressed |
| unicode | Mac resource fork | One file per revision; compressed |
| Modifier |
