Dictionary Files

The dictionary files used by PicoZip Recovery Tool are normal text files that contains a lot of words, and each word is on one line. You can create your own dictionary file by using a simple text editor like NotePad. However, it would be more practical to download ready made dictionary files from the Internet.

This website used to host some dictionary files are courtesy of The Wordlist Project. The files aren’t available anymore, but here is their meta-data just for legacy’s sake.

“PicoZip packs lots of user-friendly features that make it a joy to use. … This is a complete file compression and backup solution in one application. … If you don’t already have a file compression utility, I’d really give serious consideration to PicoZip.

“PicoZip is a program for working with and creating compressed files that has a clean, intuitive interface. I found the program very easy-to-use and that makes it perfect for both new and experienced users. It has a number of interesting features that put it a step above many other compression programs, at least to me. For example, it makes it extremely easy to do backups. At the same time it can also integrate with your email, work in batch mode, and convert from a wide variety of compression formats. I’ve looked at a lot of similar programs and found this one to be more appealing than most. … So, if you’re looking for a program for working with compressed files, take a good look at PicoZip — very well done!”

“PicoZip offers a convenient Explorer-style window, showing you all the archive files in the highlighted directory and displaying the contents in a separate pane; much easier than browsing all files, picking out the one you need from non-archive file types and then opening it in an entirely separate window. Favorite organization is head and shoulders above the competition as well, which comes in handy for those of us who compress lots of files.”

“PicoZip provides superior compressed file format control and manageability that will definitely appeal to those heavily involved in working with these types of files. … While the more advanced capabilities of PicoZip may not be that relevant to those new to working with file compression utilities, I think those who depend on these utilities for a major part of their work will definitely want to give serious consideration to this powerful, user-friendly program that is packed with power and priced very competitively.”

“You owe it to yourself, if you aren’t using PicoZip already, to give it a spin. I stress the point that I seriously doubt you’ll be disappointed. Some compression apps just aren’t worth buying because most have alternatives that are free. Well, PicoZip has stability and features that you will just not be able to find in a freely produced utility. A big kudos to Softchitect for producing an excellent grade product!”

“PicoZip integrates right into the windows shell and allows you to open almost any type of archive you can think of. Password protection, archive repair and Uuencode tools are only a mouse click away. The software also makes your archive contents more viewable with the use of filters and an easy-sorting system. … This program features one of the nicest integrations of the windows explorer I have seen in a compression program.”

Hey man, even the advanced features are simple to understand and use. This is one program made to make your life much, much easier. It’s got integrated e-mail support and batch operations that’ll help make repetitive tasks quick and painless. Heck, you can even set it up to handle routine backups automatically!”

“This file compression tool is more user friendly than Winzip, WinRar and WinAce put together. … I will never use another file compression utility. PicoZip has outdone some of the best utilities out there. Why would you download and install all those different programs, when PicoZip will do it all, and then some. PicoZip really is the best way to manage Zip files.”

“PicoZip is a great program, it has a clean interface, and incorporates a lot of options not seen in other archive programs. The ability to access more than one archive format is key since people do not want to download more than one program to open a different archive format. …
This program is filled with a lot of great features and for those who do backup their files on a regular basis, would be thrilled by what PicoZip has to offer”

Q: What are archives and all these Zip files suppose to be ?

A: An archive is typically a group of files stored in a single file in compressed form. There are many different formats for archives. They are all similar in terms of functionality, with the main difference being the compression method being used. You can identify the different archive formats of a particular archive by looking at the filename extension (the letters after the last dot, e.g. “.zip”).

Archive formats supported by PicoZip

PicoZip can create archives in 8 different formats:

  • .bh : BlakHole archive
  • .cab : Microsoft Cabinet
  • .gz : GZip archive*
  • .jar : Javasoft archive
  • .lha : Lha archive
  • .lzh : Lzh archive
  • .tar : Unix tape archive
  • .zip : Zip archive

* Please note that the GZip archive format can only store a SINGLE file. This is a limitation of the GZip format, not PicoZip.

In addition, PicoZip can extract files from 15 different archive formats:

  • .ace : Ace archive
  • .arc : Arc archive
  • .arj : Arj archive
  • .bh : BlakHole archive
  • .cab : Microsoft Cabinet
  • .gz : Unix GZip (gz/tar)
  • .jar : Javasoft archive
  • .lha : Lha archive
  • .lzh : Lzh archive
  • .rar : Rar archive
  • .tar : Unix tape archive
  • .tgz : Unix Tar/GZ archives
  • .z : Unix Compress archives
  • .zip : Zip archive
  • .zoo : Zoo archive

Please note that the above archive formats are natively supported by PicoZip, no third party software is required.

Self-extracting (SFX) archives

A self-extracting archive is an archive that is created as an executable (.exe) file, and has the ability to extract the files from within itself without the use of any third party archive utility. PicoZip can create self-extracting archives in 8 different formats. Click here to learn more.

Benefits of using archives

  • Save hard disk space. You may have many rarely used files in your hard disk which takes up a lot of space. By compressing them into an archive, you can save up to over 80% in hard disk space.
  • Save time and money. Compressing large files into an archive before sending it over the Internet saves you a lot of time and money, especially if you are using a slow connection (e.g. 56k modem).
  • Simplify backup management. If you need to backup a set of files often, storing them in archives means you only need to manage one file for each backup, rather than making copies of entire folders.

Here is the place to look for answers to frequently asked questions. If you cannot find an answer to your question from this FAQ, just enter your question below and submit it. Our support staff will answer your question within one working day. Alternatively, you can email your question to support@picozip.com.

Question 2 – Are there any issues running PicoZip on Windows 95 ?

Q: I am still using Windows 95/98. Are there any issues that I should be aware of ?

A: PicoZip requires newer versions of some system files that came with Windows 95/98. These system files may have been updated if you installed newer versions of some software such as Microsoft Internet Explorer 5.0, etc. If you install PicoZip and it does not work properly, please see Questions 3, 4 and 5. Note that this does not affect later versions of Windows such as Windows 98, Windows ME, WindowsXP, etc.

Question 3 – Why do I get the error “Missing Export OLEAUT32.DLL” ?

Q: When I start PicoZip, I get the error message “The PICOZIP.EXE linked to missing export OLEAUT32.DLL”. What do I do ?

A: PicoZip cannot run on the original version of Windows 95/98 due to lack of support for certain API functions in the old version of “Oleaut32.dll” that came with Windows 95/98. To resolve this problem, you need to download and install this file.

Question 4 – Why does my toolbar buttons have missing images ?

Q: Some of my PicoZip toolbar buttons are missing the images and “flat” button style do not work. What’s wrong ?

A: The “Comctl32.dll” that comes with your Windows 95 is an old version. PicoZip requires a newer version of “Comctl32.dll”. To resolve this problem, you need to download and install this file.

Question 5 – Why do I get the error “Error on loading Winsock 2 library … ” ?

Q: When I try to check for new version using the “Help > Check for New Version” command, I get the error message “Error on loading Winsock 2 library (WS2_32.dll) … “. What do I do ?

A: You need to update to Windows Socket 2 to resolve this problem. Download and install this file

Question 6 – Why is my registration code expired ?

Q: I tried to register my copy of PicoZip, but it tells me that my registration code has expired. Why is that ?

Question 10 – Why does PicoZip’s icon look weird in Windows 95 ?

Q: I installed PicoZip in Windows 95 and noticed PicoZip’s icons/shortcuts seem to be “discolored”. How do I fix this ?

A: Windows 95 by default only supports 16 color icons. PicoZip’s icons uses 256 colors, so when it is displayed in Windows 95, it looks rather ugly. You can fix this by making some changes to the Windows registry. Please note that you should NOT do this unless know exactly what you are doing. Here are the steps:

Run “Registry Editor” by selecting “Start -> Run”, then enter “regedit” and click OK.

Look for “BitsPerPixel” and note down the number (probably 16, 24 or 32).
Now, go to “HKEY_USERS\.Default\Control Panel\Desktop\WindowMetrics”.
Add a string value “Shell Icon BPP” and give it the same value you note down in Step 3. Note: If there is no “WindowMetrics” key, just add it, then add the “Shell Icon BPP” string value.
Restart Windows.

Q: I am using WindowsXP. I have uninstalled PicoZip, but how do I restore the original CAB and ZIP file support that was provided by WindowsXP that allows you to access ZIP and CAB files as folders ?

A: To restore CAB file support, download this file and save it on your computer. After that, right-click it, then select “Merge” from the context menu. Click “Yes” when asked for confirmation. If you want to restore ZIP file support as well, download this file, and repeat the same steps. Now, restart your computer. UPDATE: This problem has been fixed in PicoZip 2.1 and above.

Question 15 – How do I run Backup Sets from the command line ?

Q: I have created some Backup Sets in PicoZip and I would like to know how to run them from the command line. Can this be done ?

A: Yes, it is now possible to run Backups Sets from the command line (since verson 2.3).

PicoZip 2.7 and above: Just go to “Tools -> Manage Backups”. Click on the required backup set, then right click it. In the popup menu, select “Copy Command-line to Clipboard”. You can now paste the command-line to run this backup set anywhere you wish.

PicoZip 2.3-2.6: Just go to “Tools -> Manage Backups”. Click on the required backup set, then right click it. In the popup menu, select “Create Shortcut On Desktop”. Now, right click the Backup Set shortcut that you have just created, and select “Properties” from the popup menu. In the Properties dialog box, the “Target” field contains the complete command-line to execute that backup.

It should look something like this:
C:\Program Files\PicoZip\PicoZip.exe -BC “C:\Program Files\PicoZip\Backups\BakSet.zfb”

The “-BC” parameter will show a confirmation dialog after completing the backup process. If you don’t want any confirmations, use “-B” instead.
