wclayer import does not work properly with long path

[liangyuRain]

I was using wclayer to import layers. It seems that if the target directory has a long path, wclayer does not work properly.

I was importing the base layer from microsoft/nanoserver. The layer can be downloaded from https://az896309.vo.msecnd.net/containers/microsoft/nanoserver:10.0.14393.447_en-us_full_spx2q06478MkUJl5hOPmCKDgYiXoSLt3. When I imported it with

.\wclayer.exe import -i .\nanoserver_10.0.14393.447_en-us_full_spx2q06478MkUJl5hOPmCKDgYiXoSLt3 C:\temp_short

the extracted folder has 1.13 GB. However, if I imported it with

.\wclayer.exe import -i .\nanoserver_10.0.14393.447_en-us_full_spx2q06478MkUJl5hOPmCKDgYiXoSLt3 C:\temp_long\abcdef\ghijklmn\opqrst\uvwxyz\abcd\efghijk\lmnopq\rst\uvwxyz\abcdefghijklmn\opqrstuvwxyz

the extracted folder has only 81.3 MB.

I have also tried to add long path prefix:

.\wclayer.exe import -i .\nanoserver_10.0.14393.447_en-us_full_spx2q06478MkUJl5hOPmCKDgYiXoSLt3 \\?\C:\temp_long\abcdef\ghijklmn\opqrst\uvwxyz\abcd\efghijk\lmnopq\rst\uvwxyz\abcdefghijklmn\opqrstuvwxyz

wclayer failed with mkdir \\?: The filename, directory name, or volume label syntax is incorrect., so I created the directory first and ran the command again. The extracted folder also has only 81.3 MB. Therefore, I suspect that if the target path is too long, some files get ignored during the import.

Sorry, this is probably the problem of Windows explorer. The Windows explorer does not support long path, so the size becomes different.

@liangyuRain So this can be closed, right?
