User Q1:What is the "auth-ID"?

User Q2:What is the difference between all these user types (full, sub, group, external, ...)?
User A2: See [http://fex.rus.uni-stuttgart.de/users.html]
[↑ Questions]

User Q3:I have uploaded a HUGE file but misspelled my recipient's address. Now I have got an error bounce email. Must I re-upload the HUGE file?
User A3: No, it is not necessary. You can redirect the file with "user config & operation control"
[↑ Questions]

User Q4:I have uploaded a HUGE file but forgot another recipient. Must I re-upload the HUGE file?
User A4: No, it is not necessary. You can forward-copy the file with "user config & operation control"
[↑ Questions]

User Q5:Can I use an HTTP proxy?
User A5: Yes, but pay attention:
Some HTTP proxies like privoxy delay the upload progress bar!
You may want to disable proxying fex.heco-schrauben.de if you run into this problem.
[↑ Questions]

User Q6:My recipient has lost the notification email with the download-URL. What can I do?
User A6: You can resend the notification email via "user config & operation control"
[↑ Questions]

User Q7:Why should I use a special F*EX client?
User A7: When you are using F*EX with your webbrowser, you are limited to its restrictions.
With a special F*EX client [http://672335.nrum8baaj.asia/tools.html] you can

  • resume an aborted transfer
  • send several files or even whole directory trees at once
  • stream files
  • transfer files via command line
  • use an Internet clipboard [http://fex.belwue.de/usecases/xx.html]
  • do much more :-)
[↑ Questions]

User Q8:How can I upload several files at once?
User A8: Put your files in an archive file (ZIP). Your web browser cannot do that.
Or you can use a F*EX client, see [http://672335.nrum8baaj.asia/tools.html]
[↑ Questions]

User Q9:I cannot upload files > 2 GB with my web browser!?
User A9: Many web browsers have bugs in their HTML-FORM implementation. The limit mostly is 2 GB, sometimes 4 GB.
Firefox and Google Chrome have no limitation.
But remember: No web browser is able to resume an interrupted upload. You need a special F*EX client like fexsend or schwuppdiwupp for resuming, see [http://672335.nrum8baaj.asia/tools.html]
[↑ Questions]

User Q10:I need to send a file bigger than my quota allows. What can I do?
User A10: Simply ask [email protected] to raise your quota.
If you want to send a REALLY big file, you also have to tell the recipient's address because his quota also has to be raised.
[↑ Questions]

User Q11:Why is the upload status window empty and I cannot see the progress bar?
User A11: Most probably you are using a (enforced) web proxy, which cannot handle dynamic HTML pages.
A workaround is using Google Chrome, which shows the upload status by itself.
[↑ Questions]

User Q12:My download was aborted before it was finished. Can I resume the download?
User A12: F*EX supports resuming at download, but your client also has to support this feature.
Firefox e.g. is missing this HTTP feature, you need an other client like opera, wget or fexget.
[↑ Questions]

User Q13:My upload was aborted before it was finished. Can I resume the upload?
User A13: F*EX supports resuming at upload, but your client also has to support it.
No web browser has this feature, you need a special F*EX client like fexsend or schwuppdiwupp,
see [http://672335.nrum8baaj.asia/tools.html]
[↑ Questions]

User Q14:Can I integrate F*EX in my mail program (thunderbird, outlook, etc)?
User A14: Yes, if your mail admin has set up a "fexmail" smtp relay.

[↑ Questions]

User Q15:Can I use a download manager/accelerator?
User A15: Generally, no, because they suck: they are not RFC compliant and produce a LOT of unnecessary server load.
But there is one exception: axel [http://axel.alioth.debian.org/]
[↑ Questions]

User Q16:Why is there an error "FILE has already been downloaded"?
User A16: Either you or someone else have already downloaded this file. Now it is gone.
Downloads are limited to a specific recipient. One cannot share it.
Perhaps the sender has fexed it to a mailing list (which is a bad idea!)?
[↑ Questions]

User Q17:Can I fex to a mailing list?
User A17: Generally: no, because the first download makes the file no more available for others.
Contact [email protected], he can allow multiple downloads for specific addresses.
[↑ Questions]

User Q18:Sending as a F*EX user is easy, but how to receive files from others, outside?
User A18: Register them as your subusers, create a F*EX group or a one-time upload key with "user config & operation control"

[↑ Questions]

User Q19:What is a F*EX group?
User A19: F*EX group is similar to a mailing list, but for files:
When a member fexes a file to this list, then all other members will receive it.
Any full user can create a F*EX group and add or delete members.
See "user config & operation control" → "Manage your subusers and groups"
[↑ Questions]

User Q20:I am not a user of your site. How can I send a file to a registered user?
User A20: See question above: you must ask a regular user to register you as his subuser.
You will then get a specific upload URL from him.
[↑ Questions]

User Q21:Sometimes I can download a file more than once, especially when I repeat it quickly. Is the autodelete feature buggy?
User A21: The F*EX server has a grace time of 1 minute after first sucessfully download in which the file is still available. This is necessary because of some stupid "download managers" which request the file several times at once. Otherwise they would report an error to the user.

Your fexmaster has set AUTODELETE=DELAY as default, which means that the autodelete cleanup process is called once a day.

Power users (use the source, Luke!) can set a "do not delete after download" flag.

[↑ Questions]

User Q22:I have uploaded a file to a list of recipients. Will the file be deleted after the first recipient has dowloaded it?
User A22: No. Every recipient gets his own copy of the file which is independant from the others.
[↑ Questions]

User Q23:The default keep time is too short for me (sender), I need more. How can I set it?
User A23: Use fexsend, ask [email protected] or read the source code :-)
[↑ Questions]

User Q24:The default keep time is too short for me (recipient), I need more. How can I set it?
User A24: Ask [email protected] to raise your default KEEP value.
[↑ Questions]

User Q25:I forgot to download a file. Now it is expired. How can I obtain it nevertheless?
User A25: An expired file is definitively deleted. Even the admin cannot restore it.
You must re-request it from the sender.
[↑ Questions]

User Q26:When I try to download a file again, I get the error message: "file has been autodeleted after download". Can you restore it?
User A26: No. You must re-request it from the sender.
[↑ Questions]

User Q27:I have sent a second file with the same name, but the recpient has not received a second notification email. Why?
User A27: A file with the same name to the same recpient overwrites the first one if it is still there (no download so far).
A second notification email of the same file(name) is not suggestive.
[↑ Questions]

User Q28:How can I sent a more compact notification email?
User A28: Let your comment start with "!.!", then the notification email will contain only download-URL, size and comment.
[↑ Questions]

User Q29:How can I suppress the automatic notification email?
User A29: Use "!#!" as comment, then no notification email will be sent.
Of course you then have to inform the recipient manually.
[↑ Questions]

User Q30:Can I delete a file without downloading?
User A30: Add "?DELETE" to your download URL.
[↑ Questions]

User Q31:Can I get a copy of the notification email?
User A31: Add "!bcc!" to the comment field on upload.
[↑ Questions]

User Q32:Can I get a notification email on download?
User A32: No.
Such a feature is in conflict with German and European privacy laws and will not be implemented.
With email you also have no acknowledgement of receipt.
[↑ Questions]

User Q33:Can I have encrypted emails?
User A33: See [http://fex.belwue.de/gpg.html]
[↑ Questions]

User Q34:I need ACLs for group access, versioning, a file browser and integration in my local file system.
User A34: This is beyond the scope of F*EX, which is designed for efficient file transfer only.
[↑ Questions]

User Q35:I cannot download files with Internet Explorer, it tells me "Cannot open Internet site". What shall I do?
User A35: Use Firefox or any other Internet-compatible web browser, that Internet Explorer is not.
This is one of the many bugs of Internet Explorer.

User Q37:I have recived a "file.7z". How can I extract it on my Mac?
User A37: For example with "Stuffit Expander":

[↑ Questions]

User Q38:How can I prevent the fexsend error SSL3_GET_SERVER_CERTIFICATE:certificate verify failed?
User A38: Set the environment variable SSLVERIFY=0

Rationale:
Your openssl library cannot resolve the SSL certification path.
With SSLVERIFY=0 you tell openssl to ignore certification verification.
Yes, this is a crude workaround :-}
