77 * Contains functions for performing file operations like copying, pasting, uploading, moving, deleting etc. through the TCE
78 * Extending class to class t3lib_basicFileFunctions.
79 *
80 * see basicFileFunctions
81 * see document "TYPO3 Core API" for syntax
82 *
83 * This class contains functions primarily used by tce_file.php (TYPO3 Core Engine for file manipulation)
84 * Functions include copying, moving, deleting, uploading and so on...
85 *
86 * Important internal variables:
87 *
88 * $filemounts (see basicFileFunctions)
89 * $f_ext (see basicFileFunctions)
90 * ... All fileoperations must be within the filemount-paths. Further the fileextension MUST validate true with the f_ext array
91 *
92 * The unzip-function allows unzip only if the destination path has it's f_ext[]['allow'] set to '*'!!
93 * You are allowed to copy/move folders within the same 'space' (web/ftp).
94 * You are allowed to copy/move folders between spaces (web/ftp) IF the destination has it's f_ext[]['allow'] set to '*'!
95 *
96 * Advice:
97 * You should always exclude php-files from the webspace. This will keep people from uploading, copy/moving and renaming files to the php3/php-extension.
98 * You should never mount a ftp_space 'below' the webspace so that it reaches into the webspace. This is because if somebody unzips a zip-file in the ftp-space so that it reaches out into the webspace this will be a violation of the safety
99 * For example this is a bad idea: you have an ftp-space that is '/www/' and a web-space that is '/www/htdocs/'
