When source is a string, it's considered as a URI, otherwise you can pass an ArrayBuffer. 28 | > All future actions will be done on this disk. 29 | 30 | #### adf.getInfo() 31 | > Returns some basic info on the disk. 32 | 33 | #### adf.getFreeSize() 34 | > Returns the used and free space of the disk (in blocks and bytes). 35 | 36 | #### adf.readRootFolder() 37 | > Returns the files and directories of the root folder of the disk. 38 | > Each file and folder has a *sector* parameters which points to the start sector of the file or folder. 39 | 40 | #### adf.readFolderAtSector(sector) 41 | > Returns the files and directories of a specific folder that starts at *sector*. 42 | > The starting sector is usually obtained from listing the root folder. 43 | > Each file and folder has a *sector* parameters which points to the start sector of the file or folder. 44 | > Each file and folder also has a *parent* parameter indicating the parent folder so you can traverse back up. 45 | 46 | #### adf.readFileAtSector(sector,includeContent) 47 | > Returns the file info (and optional content) of the file starting at *sector* 48 | > The starting sector is usually obtained from listing a folder. 49 | > If *includeContent* is true then the *content* parameter contains the binary content of the file. 50 | 51 | #### adf.writeFile(name,buffer,folderSector) 52 | > Creates a new file into a specific folder. 53 | > It returns the sector of the new file on succes or *False* on failure. (e.g. because diskspace is insufficient) 54 | > Buffer is an ArrayBuffer with the binary content 55 | > Sequential datablocks are used as much as possible to speed up reading on an actual (or emulated) Amiga." 56 | 57 | #### adf.deleteFileAtSector(sector) 58 | > Deletes a file 59 | > Just as on the Amiga only the entry of the file in its folder is removed, all the header and datablocks are left intact, 60 | > so it's possible to reconstruct the file as long as no new data is written to the disk. 61 | 62 | #### adf.createFolder(name,folderSector) 63 | > Creates a folder. 64 | > it returns the sector of the new folder 65 | 66 | #### adf.deleteFolderAtSector(sector) 67 | > Deletes a folder 68 | > Please note that the folder must me empty so for recursive deletion you should first list the folder, 69 | > then delete all files and finally delete the folder 70 | 71 | #### adf.renameFileOrFolderAtSector(sector,newname) 72 | > Renames a file or a folder. 73 | > the maximum length of a name is 30 chars. 74 | > the characters / and : are not allowed 75 | 76 | 77 | ### additional API 78 | The following methods are available for low level disk reading 79 | 80 | #### readSector(sector) 81 | > Returns a raw sector from the disk. 82 | > A sector of a standard Amiga is 512 bytes 83 | 84 | #### getSectorType(sector) 85 | > Returns the type of the sector (headerBlock, dataBlock, extentionBlock, ...) 86 | 87 | #### readHeaderBlock(sector) 88 | > Returns a parsed headerBlock 89 | 90 | #### readDataBlock(sector) 91 | > Returns a parsed dataBlock 92 | 93 | #### readExtensionBlock(sector) 94 | > Returns a parsed extentionBlock 95 | 96 | #### readBitmapblock(sector) 97 | > Returns a parsed bitmapBlock 98 | 99 | #### readBitmapExtensionBlock(sector) 100 | > Returns a parsed extended bitmapBlock 101 | 102 | #### getDisk() 103 | > Returns the current disk structure. the "buffer" property contains the binary data of the disk 104 | 105 | ### Notes 106 | **Writing support is still a bit experimental**. 107 | Don't use it for important stuff, it certainly is **not** production ready. 108 | When writing, all dates are ignore for the time being, so "last changed" and "last accessed" dates will not be updated. 109 | 110 | 111 | 112 | 113 | -------------------------------------------------------------------------------- /tosec/index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |

What's this?

86 | This is an online tool to quickly check if your Amiga ADF files are in TOSEC. 87 |

88 | This tool uses all the Amiga TOSEC dat files from the 2017-11-01 release
89 | listing 79.042 disks. 90 |
91 | 92 |
93 |

Usage:

94 | Select a bunch of ADF files on your drive and drag-drop them onto the disk above.
95 | The TOSEC status will be checked by it's MD5 hash.
96 |
Click on a disk to examine it and extract it's files. 97 |
