You can use it to access and modify the files and directories on your server via FTP or direct file access.
eXtplorer runs natively under Joomla! 1.0 - 3.1 and can also be used as a standalone app.
If you don't have access to a friendly file manager from your hosting provider, you absolutely HAVE TO HAVE eXtplorer because it lets you manage the underlying files to your site, right from within the Joomla administrator's page. Even if you do have file management access from your hosting control panel, you still can absolutely use eXtplorer, because it so convenient, and it lets you do just about anything that you need to do to files on your server. You can upload, download, edit, rename, change permissions, compress and uncompress files. And you don't have to log into the hosting control panel to do this. Just do it from within Joomla's admin page. You don't have to be a Linux geek to do anything to the files. It's all intuitive, point-and-click. Convenience and simplicity combined! I think that this is a must have extension.
It's so good, that my only concern is that if someone ever hacked into my admin account, they could use eXtplorer do anything to any of the files on my server. (But then again, if they hacked into my admin account, I'm already in trouble anyway.) So a good practice is to zip your Web directory regularly, and download the zip file to your own system. Of course you can use eXtplorer to do this with just a few clicks.
I use this component to make fast and "live" updates to files, rename, change permission and uploading one-two files.
For "light" modding and fast updates this becomes a handy and powerful component. A must for any level Joomla Admin.
I've had to do a lot of customizing to my site, mostly bits of CSS, and extplorer makes it dead simple. Just like Windows Explorer, browse to a file, open it, edit it, save it, done!
Other features are extremely handy, such as the search function, which helps you find not only files, but content within them. Know the CSS selector but not sure what file it's in? Just do a search for it and extplorer returns a list of all files containing that string.
You can also upload, download, change permissions, diff files, and more right from the toolbar.
With all the tweaks the powers-that-be have wanted for our site, I would have been completely lost without this great tool. Highly recommended!
Please add .thtml (jreviews) to the list of editable files. I have to rename the file to .html - make the changes and then rename it back. It would be great to not have to do those steps.
I LOVE YOUR EXTENSION!!!!
Only a minor issue on 2.5.1 when open_basedir is in effect on the webserver - then it will not open. Bug found, and a fix is reported to the developer
Look for issue #40 at developers website - there is the solution (very easy to correct, should you encounter the issue)
Although in version 1.7.3 doesn't work for me, I've tried to reinstall many times to no avail. Impatiently waiting for some fixes, truly grateful.
