h3. How can I upload larger Files / Raise the Upload Limit?
10 1 Sören Eberhardt-Biermann
11 1 Sören Eberhardt-Biermann
This is a limitation set in the PHP Configuration. You can change it using .htaccess files or by simply adjusting the Value in the php.ini. Read more: [[large_uploads|How to optimize your PHP installation to handle large file uploads]].

h3. Where can I create files and directories?
14 1 Sören Eberhardt-Biermann
15 1 Sören Eberhardt-Biermann
You can find a button to create a new file or directory in the toolbar (the white button with a small star). Sometimes you have no permission to add a file or dir in the directory you are currently in. Go one level up and try to chmod the directory and make it writable for you if that is possible.

h3. I can't change the permissions (chmod) on a file/directory - the link is grayed out. What's wrong?
18 1 Sören Eberhardt-Biermann
19 1 Sören Eberhardt-Biermann
You must change the permissions using the alternative file mode: "File" or "FTP". Why? The process your PHP/Apache runs under on the webserver has its own user account. But the file/directory you are trying to chmod is owned by another user account on the webserver - usually your FTP user account. So if the chmod-link is grayed out in "File Mode" you can change the permissions on that file/directory using the "FTP Mode". If both modes don't allow access to the file, the file is owned by yet another user account on the webserver. Ask the server admin to change this.

h3. I can't delete or rename a file - the links are grayed out. What's wrong?
22 1 Sören Eberhardt-Biermann
23 1 Sören Eberhardt-Biermann
You don't have the appropriate permissions to modify anything (create, rename, delete) in the directory you are in. Go up one directory level and change the directory permissions. If you can't - see the Question before.

h3. How can I change the owner of a file/directory?
26 1 Sören Eberhardt-Biermann
27 1 Sören Eberhardt-Biermann
Well, you can't - as long as you're not root (super-server-admin). Unix-based OS don't allow chown to be executed by a "normal" user. An easy way to solve the problem is to download the files, delete them and upload them back again using FTP or eXtplorer (just where you want to edit the files from).

h3. How can I make a certain directory including all files accessible to my users? I want to use it as an upload/download-platform for other users.

eXtplorer allows you to add users and allow them to browse files and download. Just use the "Admin" section of eXtplorer.

h3. Can I upload directories or unpack achives containing directories?
34 1 Sören Eberhardt-Biermann
35 1 Sören Eberhardt-Biermann
You can't "upload a directory", but you can upload an archive file holding a directory structure (with files too). If you have uploaded that file just right-click it and select "Extract". After that eXtplorer will extract the archive and create the directory structure from the archive in the directory it is extracted to. Existing files with the same name are overwritten if they are writable.
