R-Studio 6.0 Build 151275 Thu Jun 07, 2012
New features:
+ Simultaneous image creation and scan. Now R-Studio can create an image and simultaneously scan the data being copied. In this case R-Studio creates two files stored at the same place: an image file and file with the scan info.
+ File Recovery Lists: lists of files found on disks that can be exported out of R-Studio, manually edited, than imported back, and files from those lists will be automatically marked for recovery. Such lists are very useful if you want someone who is far away to decide which files are to recover and which aren’t to.
+ RAID consistency check: you may check whether the parity blocks on a RAID are valid.
+ Image and scan info files may be saved on and load from, remote computers. This helps R-Studio to avoid transferring large data volumes over network during network recovery.

Improvements:
* R-Studio processes HFS and FAT file systems much faster.
* R-Studio processes Known File Types much faster.

Bugfixes.
- Sometimes, R-Studio might crash during disk scan. Fixed.

Moreover, such remote computer can be connected to the Internet rather than to a local network. This feature is especially useful for data recovery technicians and corporations who can now serve their clients truly remotely over the Internet and do not need to transfer large volumes of data over network. In addition, files recovered from a remote compute can be saved on a local computer or on another internet-connected remote computer with R-Studio Agent running.

Fixed:
- Some crashes under Windows 98
- Some small bug fixes

R-Studio 4.6 Build 127527 Dec 04, 2008
Added:
+ Default code page settings for the HFS file system on the Options dialog
+ The Size, Creation time, etc, columns can be hidden/visible.

Changed:
= Now virtual RAIDs are placed to the Virtual Volume Sets and RAIDs folder,
existing RAIDs placed in the System Sets and RAIDs folder.
= Parents of LDM Volumes are now placed in the LDM Components
= The Parents tab for a Virtual RAID is renamed to RAID Structure.
= Dialog Find/Mark: File Mask was renamed to Files

Fixed:
- If a disk tab was opened and the file system parameters changed, the file
system were not rebuilt automatically when the tab was opened. The user had
to click Refresh.
- When the Show Drive Files command was selected with an opened tab for that
disk showing files sorted anyhow but Real FS, a new disk tab was opened.
- A file for the Byte to byte (*.dsk) image could be opened multiple times,
there was no message that it had been opened , the same as for the *.arc
image.
- The "Close All previews" command remained active when the previewer was
closed when it was analyzing the file type.
- layout was stored incorrectly when the application was scaled to the full
screen.
- An activated Open\Create File dialog (Create Image file, Scan, Log
Settings) did not prevent from activating its parent dialogs which resulted
in the possibility to create several copies of the Open\Create File dialog.
- Non-existing folders were not created automatically during saving image
files, log files, scan information files. That is, a file could be created
only in an existing folder.
- If there was a dot in the file path, the default extension was not added
to the file name.
- Conversion of localized file names is fixed for HFS. There was no such
problem for HFS+.
- Physical drives sorting fixed
