Outline:
	This program is PHP script to offer file-sharing capabilities on by the
	WEB server that can use PHP4.

Feature:
	Up-loading and the download of the file can be done by making the shared
	folder for the WEB server, and using a browser from the client.

	The subfolder of two or more hierarchies can be able to be made in the 
	shared folder of the server, to delete the file, and to do the comment 
	edit of the file. 

	Functions such as the cutout of the file, the copies, and putting are 
	offered by using the cutting buffer. 

	Two or more shared folders according to the user can be managed. 
	Each shared folder can have an independent first folder, and neither the 
	reference nor the file copy, etc. be done between folders each other.
	The user's registration is separately done. 

	It is assumed that the size uses it in having appended it to mail when
	the file is handed over in the environment for which the FTP and SSH, 
	etc. cannot be used in the case of largeness.

	The MD5 hush is used for the attestation when logging it in. 
	MD5 hushes of session ID and the password of PHP are combined, and it 
	encrypts it by the method of putting it on the MD5 hush function further. 

System requirements:
	It verifies it only by combining Linux+Apache+PHP5. 
	(If it is HTTP server that can use PHP4 or more, it is likely to be able
	to use it.)

	JavaScript's operating becomes the condition of the client because it uses
	JavaScript for the login processing and the switch processing on the page. 

	The operation verification is done in the following environments. 

	Server:
		CentOS6.5 + Apache 2.2.15 + php 5.3.3
		Fedora Core 8 + Apache 2.2.8 + php 5.2.6
		Ubuntu 8.10 + Apache 2.2.9 + php 5.2.6

	Client:
		Windows7 + Firefox 29.0.1
		WindowsXP Pro + Firefox 3.0.4
		WindowsXP Pro + InternetExplorer7
		WindowsVista Ultimate + Firefox 3.0.4
		WindowsVista Ultimate + InternetExplorer7

Preparation:
	PHP can be used by the WEB server.

	It should be set that the place where the shared folder is made finishes
	writing it from the WEB server. 
	(It makes it to can write it by HTTP Server User.)

	The file can be up-loaded in PHP.

	Example of set item of /etc/php.ini

	  file_uploads = On		--> Indispensability
	  upload_max_filesize = 10M	--> Size of the maximum up-loading file
	  post_max_size = 10M 	--> It influences the size of the up-loading file. 


Install:

	Arcaiv is developed with the directory that the HTTP server is accessible,
	and the PHP script is executable.
	The directory named filesXXX (XXX is a version number) is made, and the 
	script file is progressed in that.

	ex:
		tar zxvf filesXXX.tgz	(XXX is a version number)

Upgrade:

	The method of the version's improving overwrites existing script files
	other than the configuration file and the password file.
	The configuration file must add only the addition item to an existing 
	configuration file or use the change in the content of an existing 
	configuration file set for a new configuration file in addition. 
	The content of the folder for data need not change.

	In default, the character-code used is us-ascii.
	To environment to use, please change it by the setting of the language to 
	mention later.

	(In that case, please reflect the content of existing installation file 
	files.conf for remembrance' sake.)

Initialization:

	files.conf in the developing folder is a basic configuration file. 

	The configuration file sets the item of one a line by the composition like 
	key word  value. 

	The point needing a change in particular is 2 of the following

		CONFIG_TOP_DIR	./config
		TOPDIR	./data

	Because CONFIG_TOP_DIR is appointment of the directories that a pass Word
	file and the preference of the folder are stored, I recommend what I change
	to the place that I cannot refer to directly by the browser.

	But it must be the place that the practice user of the WEB server can read 
	and write.

	TOPDIR wins likewise at the place that the practice user of the WEB server 
	can read and write 	You had better set it by the browser in the place that 
	you cannot refer to.

	But I can use others as initial setting, but TOP_DIR and CONFIG_TOP_DIR
	recommend what they change in total to the environment of the server to use.

	The link URL is right, and it is transcribed when I do this item value for 
	absolute notation not relative notation because it is used for link URL 
	displayed by a file list screen.

	In default, the character-code used is us-ascii.
	To environment to use, please change it by the setting of the language to 
	mention later.

	It came to be able to set the directory that stored the configuration file 
	and the password from Ver.2.1 on the management screen.

	It is revokable on the screen where the directory that stores entry page 
	(index.php) of the shared folder is also the same.

	In addition, from Ver.2.5, the choice of the indication language came to be
	possible with a management screen.

How to use:

	In the setting when developing, a set directory of the shared folder is 
	made in the config directory in the directory that can have been done by 
	developing.

	The first folder is made below the data directory right under the directory
	to which the shared folder that puts actual data progresses, too.

	URL and passing under the explanation are described assuming that the 
	script is progressed right under DocumentRoot of the WEB server. 

  1) Change in basic setting

	First of all, it connects it with http://Server-Address/files/index.php 
	by using a browser from the client. 

	Because the login screen is displayed, admin is input in user ID, nimda is 
	input to the password, and it logs it in. 

	(The manager of default gets to nimda the setting of the admin password.)

	A management screen is displayed when I log in. 
	At first please set the language.

	Please change the placement of the constitution file of it next.

	In the setting of default, if URL of the file name is specified directly, 
	the password file and the configuration file can be inspected by a browser. 

	There is no change in a dangerous thing though it is not because the
	password can be seen directly because the password part filing the password
	has passed the hash function. 

	Therefore, it is necessary to move it to the place where the password file 
	and the configuration file cannot be inspected by a browser.

	The change does the place of the configuration file from "Configuration file
	arrangement setting" menu of the management menu. 

	The file is actually moved when the setting is executed on the configuration
	file arrangement setting screen, and set it carefully, please. 

	Next, please do "Password setting" when you can do the configuration file 
	arrangement setting. 

  2) Making of shared folder

	In the shared folder list, the list of the made shared folder is displayed.
	The folder list is a link to the folder that becomes an object. 
	It changes in the setting and the deletion also is linked with the screen 
	here. 

	In the shared folder making, the shared folder is newly made. 
	A set name of the shared folder becomes the storage directory name of the 
	configuration file.
	The first directory of the folder actually shared is specified for the 
	first folder.
	The first directory is done by the relative path from the directory in the 
	script in specification or the full path.

	From version 2.4, I got possible to appoint even the directory which 
	I cannot refer to in URL directly.
	You had better appoint the directory which did not have the management of
	the WEB server below in top folder when you considered security.

	From version 2.5, I was able to use a link to the direct file without
	using a download script.

	When size was more than 2GByte, this established it for evasion for what
	I cannot download in the cases that wanted to show a big file of the size.

	In that case, a WEB server must set the top folder in access possibility, 
	the writable place.

	When the folder under the management of the WEB server is specified, the 
	following content in the directory for data. You will put the htaccess 
	file, and do measures of the acceptance only of the access from the link 
	on the page after specification URL etc.

		SetEnvIf REFERER "^http://www\.example\.com" ref_ok
		Order deny,allow
		deny from all
		allow from env=ref_ok

	(The above-mentioned is a description for Apache.)

	Additionally, please set it suitably.

	The directory of the name same as setting name is made under the directory 
	which I appointed in CONFIG_TOP_DIR of preference (files.conf) when I make 
	a shared folder, and a preference and a pass Word file are begun to write 
	in that.

	The configuration file name becomes .conf.

	The content that can be edited on a set screen is only a part of very item
	of the configuration file.
	Because the configuration file can be edited in the editor, other detailed
	items are edited in the editor.

	I temporarily think that it can use it only by setting the above-mentioned.

	When the shared folder is made, the shared folder list screen is opened.

	A set name of the shared folder list screen or URL is a link of the shared
	folder to the login screen.

  3) Operation of shared folder:

	The name or URL of the made folder is selected from the list screen. 

	It logs it in here with user ID = admin and password = nimda because it 
	jumps to the login screen to the made shared folder. 
	(Please change the password of admin after it logs it in.)

	The screen of the file list that is basic of the operation of the shared 
	folder is displayed. 

	The link of "Make Folder", "Upload", and "Password Setting" to each
	function is displayed in the upper part of this screen. 

	The subfolder is made by "Make Folder", and the file is up-loaded from 
	the client by "Upload".

	The movement to the made folder selects the icon of the folder name or the
	destination head. 

	The movement from the lower folder to a upper folder selects the name of a
	upper folder of the first line or the arrow icon. 

	The name of the up-loaded file is displayed as a link in the list.
	This link is selected and it downloads it to the client when downloading it. 
	The comment is edited, is deleted, and copied, and it cuts out and the icon
	on the side of file name is selected.

  4) Edit of configuration file:

	The character-code of the configuration file is described by the character-
	code used with the system, and changing line uses only LF. 

	A set item is describes one item a line, and the following forms. 

		keywordvalue1value2value3

	TThe key word begins from the head of line, and the delimitation with the
	value is delimited with Tab. 

	Do not put two or more Tab in the delimitation.
	Set value2 and set value3 are by the kind of the key word and there is a 
	no potato, too.

	The line where "#" is at the head is a comment. 

	The item of the configuration file is written at the head of the 
	configuration file by the comment, and refer to that, please.

		Get_post_get_val() of files_com.php is corrected and it deals with the
		escape by the backing slash. 

Ver.1.0.3  2004/05/23
		Because JavaScript of the MD5 hush making doesn't operate correctly by
		a browser on MacOS.
		It is corrected that use conditions and MD5_PASSWD_USE of MD5 can be 
		added to the configuration file, and three kinds (YES, NO, and NO_MAC)
		be set as a value.

Ver.1.0.4  2005/08/02
		The icon definition file of the file is cut out to another file, and 
		the edit method is added by the comment. (Because the icon addition 
		was demanded. )

		The description of the download method was added to help. 

		It is corrected that the superscription is confirmed when file 
		up-loading it.

		It is corrected that it makes it to the one that manager's default 
		password was specified by not the blank but the configuration file.
		In default, it is the following settings.
			Manager user ID : admin
			Manager password: nimda

Ver.2.0	2007/09/05
		To change by correcting only locale.php in the displayed character 
		string, the display character string was separated to locale.php as 
		an array. 
		The displayed character string acquisition is corrected to do by using
		get_txt().

		Add the permission setting function to use the group and the user.

		To use not the link but the download script, the method of downloading
		the file was changed. 
		(As a result, downloading it even if the data folder was not the under
		of the management of the WEB server became possible.)

		The script had in the configuration file and all users had reading and
		writing can enabled the permission of the made file.(PERMIT_ALL=YES)

		The configuration file was prepared according to the character-code.
		The directory for the file that depended on the character-code for the
		filesXXX/locale under was prepared, and the configuration file for four
		kinds of character-codes of euc-jp, utf-8, shift-jis, and us-ascii was
		prepared. 

Ver.2.1	2007/12/01
		The index.php filing in which a link to a login screen was written was
		done in order to make a setting file at the place different from a 
		password file.

		I deleted an unnecessary description of download script download.php.

		The configuration file arrangement setting was added to the management
		menu. 

Ver.2.2	2007/12/07
		The character-code in the script released with Ver.2.1 replaced it because
		there was something that 'BOM' mixes with the file of UTF-8.

Ver.2.3 2008/02/09
		It was corrected that ini_set() was executed in the session_start() 
		front because it had become an error by session_start() in the version 
		before PHP 4.3.3 occasionally. 

		Because function stripos() not supported with PHP4 had been used, 
		it changed to use stristr() instead. 

		When a pass of a folder for setting files was established by the same
		condition by composition file arrangement setting, the defect which 
		puts out an original setting file was corrected.

Ver.2.4 2008/03/25
		URL for the connection to the login screen was displayed. 

		The method of linking the download files was changed. 

		When the file of a Japanese name was downloaded, the file name was 
		converted in consideration of the kind of a browser.

		Because link ahead to the file of the cut buffer was wrong, I revised it

Ver.2.5 2008/12/11
		The character set used by HTTP header was specified in front of HTML.

		A part of function was moved from files_com.php to session.php.

		Because return destination URL had not been correctly set, it corrected it. 

		I changed it to treat file size with 32 bits unsigned integer.

		I added the setting screen of the indication language.

		Besides the use of the download script, I was able to use a direct 
		link to the file.

		A value to set in a variable to save current directory was funny and 
		revised it because there was the case that a pass of a file cannot 
		set definitely.
		(BUG was able to be discovered by the favor that the point is gotten 
		on the bulletin board. Thank you so much.)

Ver.2.6 2009/03/25
		When an error occurred by upload, I was able to display a message and 
		return.

		When a config file name was not handed, I acquired it from a session 
		variable.

		Because warning was given by cf. variable that was not set, I checked 
		it earlier.

		I changed the check order of the global variable to take the file 
		names of an uploaded file.
		$_FILES >> $HTTP_POST_FILES >> $UploadFile

		It previously checked it because it opened and it deleted it without
		doing the existence check of the file and the directory.

		I revised the mistake of the variable(new_conf -> conf)

		I revised it there was it before deleting a file, and to check it. 
		iSo that warning is not output by logj

Ver.2.6.1 2009/11/08
		In Internet Explorer, without opening the file in the application, 
		so you get a save dialog.

Ver.2.6.2 2014/05/23
