AnCrypt v1.038
AnCrypt AnCrypt is a Notepad-like text editor which crypts the edited files (BlowFish 448bit algorithm). It can be used to carry confidential data on an USB key.

Encrypting a text file enables you to keep its content safe. Typical uses of this program would be to store passwords you can't remember, or other important information you wouldn't want other people to see.

Specially designed to be small and easy to move around, this program has nearly the same interface as the default Windows notepad. It doesn't require any installation, and allows you for example to bring it along with your sensitive data on a floppy or an USB key.

This program relies only on encryption to protect your data, and does not offer any protection against phishing attacks like memory dump, window text copy, screenshot analysis, clipboard hijacking, swap file access, keylogger, ...
If you suspect you are in an hostile environment, do not open your encrypted file.

AnFV v1.0
AnFV AnFV enables you to perform advanced integrity check on files. Unlike many other similar softwares, AnFV pinpoints the location and extent of one or more erroneous blocks in a checked file.

The easiest way to check that a file is the same as an original is certainly to compare it byte by byte to the original. However, when the original is not available on site, for example in the case of a downloaded file, it is impossible to do so without having to download it once again. In this case, the most widespread method to check that a file is not corrupted is to compute a kind of magical number for the original file, and to compare it to the one computed for the downloaded one.

This kind of computation is called hashing, and the magical number is a hashcode. There are plenty of ways to hash data, amongst which we find the well-known CRC-32, MD5 and SHA1. If the hashcodes obtained on two blocks of data are different, we are sure that the two blocks are different. However, the reciprocal is not necessarly true, and given a hash method there is a small chance to obtain the same hashcode on two different blocks. The SFV-like file checking tools only generate one hashcode for a whole file, which is surely enough to find out that a file is corrupted, but doesn't allow for example to see that only the last 12KB of a 380MB file are corrupted. This information might allow to retrieve only the corrupted data, which in most cases is clearly faster than downloading the whole file once again.

AnFV enables you to create validation files for other files. These files contain a set of hashcodes that allow to locate corrupted blocks within a bad file with a customisable resolution. The block size can be reduced up to 256 bytes of data per block. AnFV can still use the SFV format, but in that case it won't be able to tell you where the errors are in a corrupted file.

DriveSort v1.230
DriveSort DriveSort sorts the directory tables of a volume formatted in FAT12, FAT16 or FAT32. This sort orders the files on the disk according to a customizable order.

Recent operating systems sort the files before showing them to the user, either by name, by size or by whatever the user choose. However, it is not always the case in embedded OSes on small portable devices like MP3 players. On these devices the lack of resources (CPU, memory) can lead their developers to make it display or play the files in the order in which they are on the disk.

This order depends mostly of the order in which they were added to the disk, which is not convenient for the user. DriveSort can change this order to help such devices to play or view their files in the order you want, by putting them on the disk in a customizable order.

DriveSort sorts files and folders according to various options available in the popup menu next to the sort icon. The order can then be saved to disk either folder by folder, or for all sub-folders.

  • The comparison base:
    • "Short name": sorts the files and directories according to the alphabetic order of their Short File Names [Default].
    • ( A file or directory on a FAT volume always has a short file name, which is the old MS-DOS 8.3 name format. It means that the name part of a filename must have at most eight characters, and its extension at most three. A file or dir can also have a long file name, which can be a bit longer than 250 characters, and supports Unicode characters. When a file name contains mixed case, or has one part that doesn't fit in the 8.3 convention, the file has both short and long filenames. )
    • "Long Name": sorts the files and directories according to the alphabetic order of their Long File Names.
    • "File Size": sorts the files and folders according to their size on disk or for folders according to the sum of the sizes of all files and folders in the folder.
    • "Creation Date": sorts the files and folders according to their creation date and time.
    • "Access Date": sorts the files and folders according to their last access date (no time for this date in the FAT format).
    • "Update Date": sorts the files and folders according to their last modification date and time.
  • The sort direction: "Ascending" [Default] (aaaa.txt before aaab.txt) or "Descending" (aaab.txt before aaaa.txt)
  • The position of folders relative to the files:
    • "Before the files": Groups the folders together at the top of the name table, and sorts the files separately. [Default]
    • "After the files": Groups the folders after the files, and sorts the files separately.
    • "Mixed with files": No difference between files and folders, they are all sorted together.
  • The recursive mode which sorts a folder and all its sub-folders by checking "Subdirectories".

DriveSort also features a manual ordering mode for files: the "playlist" mode, in which you can drag the files in the list in the order you want. This mode is only available on the files having a long file name, because it alters the content of the short file name of the ordered files. If it was used on a file having only a short file name, the name would be lost. The short file name is altered to become something like "XXXXXXXX.EXT", where XXXXXXXX is the file's playlist number, and EXT is the file original extension. The long file name of the files is not modified, and the files are automatically ordered on the disk using "Short Name" comparison. This is particularly useful for multimedia players which play the songs using the short file name alphabetic order, and display them using their long file names, such as the I-Bead, the Sony K750i, some devices for GBA/NDS... The playlist mode is initially able to move .MP3, .OGG and .WMA files around, to avoid files that are not really part of a playlist, like system files. If you want to add other extensions to these, use the Extensions... menu in the playlist menu, or add them to the RecognizedExtensions option of the DriveSort.ini settings file.

DriveSort needs the latest x86 Visual C++ redistributable components installed to run, and will show an error message mentioning missing DLLs such as mfc140u.dll, vcruntime140.dll or some others with names like api-ms-win-crt-*.dll when they're not present. These are available for free from Microsoft and compatible with recent Windows versions (Windows XP to Windows 10). On the most recent Windows versions these components are usually already deployed and kept up to date by Windows Update. If you need to install them, you'll find the official installer for these components here: [ vc_redist.x86.exe ] or in the latest supported Visual C downloads.

DriveSort works directly with the basic structures of the file-system, so be careful when using it, and backup anything important before. DriveSort can create a full backup of a disk or a partition from the disk selection dialog context menu.

Use this program at your own risks.

jSAVF v1.31
jSAVF jSAVF enables you to consult and check the integrity of an IBM iSeries (AS/400) SAVF save file on a workstation with a recent Java runtime environment. No connection to an iSeries is needed.

jSAVF can open a SAVF file with the menu or a drag-and-drop. Once a SAVF is open, the objects are listed in a format similar to the one provided by the DSPSAVF command. You can export this list to a text file using the Print menu in a format like the one provided by the DSPSAVF *PRINT command. You can order the displayed objects by one or more criteria using the list headers and search them by name.

The SAVF file format analysis has been done with a good hex editor and some info found in the archive.midrange.com forum (particularly the two IBM proprietary checksum algotithms). jSAVF supports either uncompressed SAVFs (*NO), those compressed with the old compression method (*YES before V5R3, *LOW since then), and those compressed with the more recent methods (*MEDIUM and *HIGH).

The internal structure of some object types has been analysed so they can either be displayed in jSAVF as text spools, or exported as files.

  • The SAVF files included within a SAVF can be exported as valid SAVF files, which can in turn be opened by jSAVF.
  • The data areas (*DTAARA) of all types (*CHAR, *DEC, *LGL) can be displayed or exported as text as the DSPDTAARA command would, or more concisely as the RTVDTAARA command would.
  • The analysis of the other types is ongoing, meanwhile the raw objects and members can be exported.

The integrity checks performed by jSAVF are:

  • The file size is validated against the SAVF header information, to ensure it is not truncated.
  • The blocks read by jSAVF are checked against the block checksums in the SAVF. jSAVF will therefore control the integrity of part of the SAVF during its indexing, and will also control the blocs required to display or export the objects you chose to display or export.
  • There is also a menu allowing you to verify the integrity of all SAVF blocs at once, and the global file checksum.

Prerequisites

  • The data conversions between EBCDIC and Unicode require some Java codepages which are optional in some JRE versions. If you install a JRE, ensure you check every install option, otherwise some SAVF might not be readable.
  • jSAVF requires a JRE v1.8 or above.

Limits

  • jSAVF has limited support of SAVF generated on the IFS filesystem (SAV command)
  • jSAVF can sometimes fail to read SAVF generated either with exotic SAV* commands or by very old OS/400 releases.
