However, I have tested XFolder with several system utilities that I could reach at this time (on both Warp 3 and 4), and a number of users reported other utilities to me. The following programs seemed to be cooperative:

• CandyBarZ 1.01 / 1.10
• CommandFolder 1.50
• Desktop Wizard 1.41 (mind the notes below)
• DragText 2.5
• Extended Desktop 1.4
• FeelX (installs a WPS class)
• Hot Scroll 0.80 / 1.00
• NPS WPS 1.81 / 1.82 (mind the notes below)
• Object Desktop Professional 1.5.2 (mind the notes below)
• WatchCat 2.1 (installs a WPS class)
• WPAnimatedMousePointer 1.01
• WPS Trashcan 2.5.2
• X.file 1.1 / 1.2
• X.it 2.4 / 2.5

Moreover, since XFolder offers a number of features which are also contained in other WPS packages, you should make sure that these features are not enabled in several packages at the same time. For example, you should not enable folder status bars in both XFolder and Object Desktop, which can only lead to problems.

Warnings. The following list of incompatibilities is based on reports by users of XFolder. I have not verified these yet and include them only to save you from trouble.

• Object Desktop. OD manipulates the WPS just as intensively as XFolder does (maybe even more), so it's just natural that most problems have arised with this software.

  Note: I do not have Object Desktop. The following is all I know. If you find out something, you're welcome to tell me, and I'll add that to this section. But please do not write me that OD does not cooperate well with XFolder. I know, and there's little I can do about it.

  For all versions, the following rule applies: If you have trouble, XFolder probably conflicts with OD's folder replacement class, TSEnhFolder. If nothing else works, you can always deregister that class (using the "WPS Class list" in the "Workplace Shell" object), and you'll probably get XFolder to work.

  But before that, mind the following notes:

  The install program now offers you to alter the order of XFolder and the "TSEnhFolder" class in the WPS class list which is the WPS class responsible for most of the Object Desktop folder functions. I believe this should help, because then XFolder gets the chance to subclass the folder windows before Object Desktop.

  Object Desktop 1.x.

  I was reported that XFolder does not cooperate with the "Browse mode" feature of Object Desktop. You will have to switch this feature off, sorry.

  Also, you should make sure to have the "Folder status bars" disabled in Object Desktop before enabling the respective XFolder function, or the funniest things might happen.

  Finally, I was reported that XFolder keeps adding status bars to Object Desktop's "Launchpads" even where they don't belong. Apparently, these things are derived from the WPFolder class also; they have an "XFolder" page in their settings notebooks though, so you can turn off XFolder's status bars for them.

  Object Desktop 2.0. Stefan Zechmeister got OD 2.0 to work with XFolder doing this:

  1. Install OD 2.0.
  2. Install OD fixkit #1.
  3. Install XFolder. Reverse the order of TSEnhFolder class as proposed by the install script.
  4. Go to the "Workplace Shell" object, "XFolder" page 2 and raise the "Menu item ID offset" to above 700.
  If you then move XFolder's installation folder to another folder, make sure the target folder has OD's extra features turned off. Otherwise XFolder will complain that its Configuration Folder does not exist.
  
• If you are using NPS WPS, you must make sure to have its "Select by name" and "Sort by extension" features disabled, because XFolder offers these features also and gets confused if these features are added by NPS WPS also.

  XFolder does not work with the automatic menu selection of NPS WPS, at least not if you are using the "Folder content" functions. Sorry, you'll have to turn that feature off.
  

• I was reported that XFolder seems to have problems cooperating with Program Commander/2. Apparently, this can be solved by switching off the "SmartIcons" feature for title bars.
  
• XFolder also seemed to have problems with DragText on some systems. There must be a setting somewhere in that software to start DragText delayed, which should solve this.
  
• I was told by Hauke Laging that Extended Clipboard (EClip) by Hinnerk Becker does not cooperate with XFolder. On Hauke's Warp 4 system, the WPS hung at startup and did not respond to anything. Hauke then told me that the problem can be resolved by removing EClip from the startup folder. (I was unable to reproduce all this, but I'm reporting this to you anyway.)
  
• Several users also reported that the "Snap to grid" function did not seem to work. I have tested both Warp 3 and 4 and encountered no problems; these users all had some version of Object Desktop installed, so I suspect in respect to the "Snap to grid" feature, XFolder and Object Desktop seem to be colliding somehow.
  
• Bernd Schemmer reported that XFolder seems to be using the same menu ID's as the LAN Server GUI. If you're using LAN Server (or other software that might suffer from this), you can now change XFolder's menu IDs in the "Workplace Shell" object. The default menu ID offset has now (V0.51) been raised from 100 to 300 to avoid these conflicts.
  
• Michael Holzapfel reported that installing GRADD drivers for the ELSA Winner 2000FC video card crashed his system when XFolder V0.71 was installed, causing a CHKDSK at the next reboot, which in turn damaged the newly installed drivers, so the system wouldn't start at all. He told me that de-installing XFolder helped.
  
• Dirk Schulz reported that Desktop Wizard and XFolder don't like each other too much. On his system, he was able to increase the WPS's stability by de-installing Desktop Wizard. Glad he didn't de-install XFolder. ;-)
