FBinds (extract)
An FBind is an image with a file hidden inside. This file can be anything from music to programs, so take care when opening files from unknown FBinds!
Opening FBinds(ex) pane
To start making an FBind, simply click "FBinds (ex)" in the main sidepanel, or select "FBinds" in the second dropdown menu top-left in the window.
Selecting FBinds source
If you wish to find all FBinds in your image database, click the red button where it says From imported images. This will make pImgDB scan through all your imported images for FBinds, and should only take a couple of seconds. However, many FBinds are made using a simple icon to imply what filetype it contains. As pImgDB automatically removes exact dupes, most FBinds will probably be skipped during an import.
If you instead wish to find all FBinds in a folder of images, click the other red button where it says From custom folder. This will allow you to select a folder, and pImgDB will search through all images in that folder (and subfolders) for FBinds. While this will take longer than using the From imported images button, it will catch all FBinds - even though their carriers might be exact dupes (the popular pFBind icons).
Browsing identified FBinds
Once pImgDB has found all the FBinds, you can browse them by selecting each of them in the big list. Once you click an FBind, pImgDB will extract all the information about the embedded file. This will be displayed to the bottom right. The name of the embedded file will be displayed next to Filename, its size next to File size, and its crc32 checksums (primitive fingerprint) will be displayed next to Hash. Note that there's two hashes in the Hash field.
The first hash is the file's correct checksum, while the other hash is the one of the file right now. If these match, the background of the Hash field will be green - indicating that the file is in good shape. If they don't match, the background will turn red, indicating that the file is corrupt. The first checksum might also be Unknown. This can mean one out of two things. Either the end of the embedded file is lost (which means that it's corrupted), or it was made by an old version of pFBind. In the first case, the embedded file probably won't work. In the second case, it's probably just fine. Just have a go at it, and see which is the right reason.
Extracting one or more FBinds
First though, you have to select a folder where pImgDB should extract the FBinds. By default, this is a folder named "fbinds" in pImgDB's own folder. If you wish to change this, click the "..." button towards the bottom right. Now, select all the FBinds you wish to extract. Select one by clicking it normally, then Ctrl-click the others if you want to extract more than one. You can also click-drag across the list of FBinds to add a huge bunch of them. Confirm your selection by pressing Extract selected now.
