Text Files Register 0 Bytes even with 90K Characters, Cannot E-mail

Sometimes it's as simple of clicking the Name at the top of the column in Details view then click it again to get the list refreshed. Also usually works to close and open File Explorer and navigate to the folder that contains the file. Keep in mind that a folder cannot contain 2 files of the exact same name, one has to be at least one character different. And possible to open a file in the program used to create it, see if there's actually anything in it. Also possible to open that program then File, Open and see it's listed.

 

Searching file names using wild characters

In searching File Explorer (Win10) the wild character "?" doesn't seem to work when searching for a file name. e.g. "?E1" doesn't produce a list of files having E1 as 2nd & 3rd character in file names. Used to work beautifully in Win 7.

 

File name length & permissible characters and Access right of OneDrive

I am using OneDrive every day and it works good. However it cannot replace SSD or Hard disk. I have a no of difficulties and seeking advice to minimize the impact on use.

• What is the max characters of a file name including sub-folders in between?
• Is there any restriction of permissible characters for the file name including language such as Japanese, Chinese, etc.?
• How can I set the access right of allowable file placement but cannot erase any files?

Thanks and regards!
