I have been using Alpha 5 for two years now and I have dozens of files beginning with the $ sign in the Alpha directory. I assume these are temporary files which I can delete. Is this the case? Also why does Alpha create them?

The Alpha Software Forum is a free forum created for Alpha Software Developer Community to ask for help, exchange ideas, and share solutions. Alpha Software strives to create an environment where all members of the community can feel safe to participate. In order to ensure the Alpha Software Forum is a place where all feel welcome, forum participants are expected to behave as follows:
Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
Moderators may also rename posts and threads if they are too generic or do not property reflect the content.
Moderators may move threads if they have been posted in the incorrect forum.
Threads/Posts questioning specific moderator decisions or actions (such as "why was a user banned?") are not allowed and will be removed.
The owners of Alpha Software Corporation (Forum Owner) reserve the right to remove, edit, move, or close any thread for any reason; or ban any forum member without notice, reason, or explanation.
Community members are encouraged to click the "Report Post" icon in the lower left of a given post if they feel the post is in violation of the rules. This will alert the Moderators to take a look.

Bonus TIPS for Successful Posting
Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.
When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.
The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.
When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.
A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.
If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.
When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.
Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.
- Be professional in your conduct
- Be kind to others
- Be constructive when giving feedback
- Be open to new ideas and suggestions

Be sure all comments and threads you post are respectful. Posts that contain any of the following content will be considered a violation of your agreement as a member of the Alpha Software Forum Community and will be moderated:
- Spam.
- Vulgar language.

- Personal attacks, insults, or subtle put-downs.
- Harassment, bullying, threatening, mocking, shaming, or deriding anyone.
- Sexist, racist, homophobic, transphobic, ableist, or otherwise discriminatory jokes and language.
- Sexually explicit or violent material, links, or language.
- Pirated, hacked, or copyright-infringing material.
- Encouraging of others to engage in the above behaviors.
If a thread or post is found to contain any of the content outlined above, a moderator may choose to take one of the following actions:
- Remove the Post or Thread - the content is removed from the forum.
- Place the User in Moderation - all posts and new threads must be approved by a moderator before they are posted.
- Temporarily Ban the User - user is banned from forum for a period of time.
- Permanently Ban the User - user is permanently banned from the forum.

RE: Files beginning with $
Bil, as always, is correct. Sometimes Alpha doesn't delete the files, even though you have made the suggested settings. I'm including a script (author undientified, supplied by another board member, and though I've searched, I can't identify) that will delete .mpx files. It can easily be modified to delete any other files you like. Best attached to the onexit event of your startup form.
''XBasic
on error goto no_mpx_files
files = filefind.first(:A5.Get_Shared_Path() + chr(92) + "*.mpx")
WHILE .not. files.eof()
table_name = files.name() 'cleanup alpha
file.remove(table_name)
files.next()
end while
END
no_mpx_files:
on error goto 0
ENDThere can be only one.

Stan,
I've been wondering about that myself. Thanks for the answer and the code.

RE: Files beginning with $
Stan,
The code you listed (I know you don't take claim for it!) will not work correctly for 2 reasons. First and foremost is the fact that mpx files are stored in the Private Path, not the shared path. On many systems this is the same, but not always. Second, if there is an MPX file currently in use, an error will occur and the code will stop immediately.
Listed below (and attached as a ZIP file) is code that works a bit better.
