Please note that the following F.A.Qs only apply to the latest version of HFS, version 2.0. If you do not already have this version, please download it at

Q1: What is HFS?
A1: HFS is a portable software that allows you to share files between friends and family with ease. HFS is so small that it could even fit on a FLOPPY DISK!

Q2: How much does HFS cost?
A2: HFS is completely free! However, if you like the project, please donate by going to .

Q3: I like this software! How do I donate?
A3: You can donate to the HFS project by going to and clicking the Donate button.

Q4: Does HFS contain spyware, trojans, or any malicious software?
A4: Of course not! We respect the rights and privacy of our users and does not bundle "junkware" unlike other free software(s). If you like HFS, please support HFS by donating!

Q5: What protocol(s) does HFS support?
A5: As of now, HFS only supports the HTTP 1.1 protocol.

Q6: Will HFS support the FTP file transfer protocol?
A6: FTP support is planned, but please don't expect it soon as it would probably come on a major release after v2.0.

Q7: Does HFS support server-side scripting such as CGI or PHP?
A7: No, HFS currently does not support server-side scripting such as CGI or PHP. Although this is planned for a later version, please keep in mind that HFS is meant to be a file sharing server.

Q8: When I share a file in HFS, it always asks me to download. I just want it to appear in the browser! (like images, etc)
A8: By default, HFS tells the browser that files should be downloaded and not viewed. To change this behavior, click Menu, Other Options, than click Open directly in browser... Here you can specify which files type you want HFS to directly display in the browser. (For example, *.gif;*.jpg) (File types are separated by semicolons and wildcards * are supported)

Q9: I do not like HFS's web interface, how do I change the look?
A9: If you are knowledgeable in HTML, you could edit the HTML template by selecting Menu, Other Options, Edit HTML Template...
(No WYSIWYG editor is available for editing the HFS template)
You might also be able to find customized templates by our users by looking around in the forum.

Q10: HFS reports the error "Cannot open port". What should I do?
A10: This usually means the port that HFS tries to use is in use by some other application. To fix this, specify another port (1-65535) in the port box, and click the OFF button to switch the server on.
P.S. It is recommended that you pick a high port range such as 17019 or 31028, etc.

Q11: What is the difference between Expert and Easy mode?
A11: In easy mode, a lot of HFS options is hidden from the user's view for the usability of the software for beginning users. If you are fairly knowledgeable about HFS, it is suggested that you use the Expert mode.

Q12: My download is interrupted! Does HFS supports resuming of impartically downloaded files?
A12: Yup! HFS supports HTTP 1.1 download resuming with the help of a download manager.

Q13: My friend is uploading to my HFS server, but the upload got interrupted. How could I resume the upload?
A13: Currently, the HTTP 1.1 specifications does not contain commands for resuming impartially uploads. Therefore, this feature will not be implemented in newer versions of HFS. (Unless FTP support is implemented)
Please note that HFS could be configured to delete impartially uploaded files.

Q14: How do I protect my files on the HFS server? Are they safe from Internet hackers?
A14: You can set a username and password for a file by right clicking on the file and selecting Set user/pass... This, however, will not protect your file from prying eyes when they are downloaded by an authorized user since HFS does not encrypt the data that is being sent.

Q15: What does the "hand" icon represent in the file system tree?
A15: If you see an icon that looks like a hand, it means that HFS could not find/access the original source file. HFS will hide the file from the web interface until HFS could successfully access the file in question.

Q16: I can locally access my HFS server, but when my friend tries to access my HFS server, they get the "Unable to connect" or "The page cannot be displayed" error. Why?
A16: This problem is most likely to be caused by a router or a firewall. If you are currently under a network, please make sure that the correct port is forwarded to your computer. (Instructions are available on ) Additionally, try disabling software firewalls or enable HFS server permissions if applicable.
To simplify this process, use the Self Test feature in HFS2 by clicking Menu, Self Test. The self test will let you know whether or not your HFS server is working properly.

Q17: How do I allow someone to upload to my server?
A17: In order for someone to be able to upload to your HFS server, you must first create a "real folder" in the HFS file system. To do this, simply drag a folder from Explorer and release it into the HFS window. A prompt will ask you whether you want the folder to be a Virtual or Real folder. Click Real folder. After the folder is created (red-icon), you may set password permissions by right clicking the folder, and choosing the Upload submenu.

Q18: What is the difference between an user account and an user/pass combination?
A18: A user account is basically a shortcut for the user/pass combination since you simply select the user and HFS fills in the user credentials for you. Otherwise, HFS allows you to define user and passwords for different resources freely.

Q19: How do I add a comment to the password box that pops up when a user tries to access a password protected resource?
A19: You could specify this comment by right clicking the resource, and then by selecting the Customized realm selection.

Q20: I am trying to serve small amounts of HTML pages via HFS and wants to define an index page. How do I do that?
A20: You could specify the index file mask by right clicking the home icon, and then by clicking the Default file mask selection.

Q21: How do I change the default favorite icon on the HFS web-interface?
A21: If you have a customized favorite icon you want to use, simply rename that icon to favicon.ico and drag it into the HFS file system. After that, you may choose to hide the file by right clicking the file and choose Hide.

Q22: I am sharing a lot of files at once. Could I have HFS download multiple files or download the whole folder?
A22: Currently, HFS does not support downloading multiple files nor the whole folder at once. However, this function is possible with the help of an existing download manager. (Firefox users see: )

Q23: Could I upload multiple files or the whole folder at once?
Q23: HFS does not support upload of the whole folder at once. However, users could choose to upload multiple items by selecting them one by one on the HFS upload page. (By default, multiple upload fields are offered)

Q24: How do I make HFS startup every time I start Windows?
A24: To make HFS startup every time Windows start, simply create a shortcut to HFS within Programs -> Startup in the start menu.
(For easier drag and drop shortcut, it might be easier to open the start menu by right clicking it and then click Explore)
